Color Vision deficiency could be acquired too. Certain drugs prescribed for arthritis, depression, heart disease, high blood pressure, diabetes, multiple sclerosis, and some liver diseases can significantly affect color vision either temporarily or permanently. Continued use of aspirin can also alter color perception. Excessive use of tobacco and alcohol can have similar effects. Many industrial chemicals can permanently alter your color vision.
Certain eye diseases such as glaucoma, cataract and most eye problems affecting the retina or nerve pathways to the brain can give gradually impair your appreciation for colors. Overall blurring of near or distance vision, or gaps in the field of vision may also alter color vision perception.
Since color vision changes can be an early sign of a disease or a side effect of prescribed medication, it is important that you consult an ophthalmologist if you are experiencing any changes in your color vision. It is noteworthy that unlike inherited color deficiency, both men and women are at equal risk for the acquired color vision problems and only one eye is affected at a time.
Yes, both the procedures are approved by FDA. Specific amounts of correction approved for treatment vary according to specific laser manufacturers.
Usually, both eyes are affected. One eye starts damage earlier than the other does. If you have an asymmetric appearance of the optic nerves, you may be considered a glaucoma suspect.
No, there is no known relationship between flashes or floaters and any of these problems.
Do not worry if you have a few floaters. Generally, a few floaters do not mean that you have a serious eye problem. You need to see your eye doctor for an eye exam if a large number of floaters suddenly appear in your vision, or if they seem to worsen over time. If the floaters appear along with flashes of light or if you have any vision loss, you should seek immediate medical attention. These could be signs of a serious condition, such as, retinal tears, hemorrhaging due to diabetes, or high blood pressure. It is important that you see a doctor because retinal tears and hemorrhage can cause vision loss.
Small or conspicuous blood spots over the white of the eye are common. They are harmless and usually clear in a matter of days or weeks.
There is a very slightly increased risk of surgical complications, such as displacement of the IOL, but most people feel that the benefits far outweigh the risk. Today, almost all patients having cataract surgery safely choose an IOL as part of the procedure.
No, there are no dietary restrictions before or after the Radio-Surgery.
Anesthesia medications can cause stomach upset. The best way to prevent after effects from anesthesia will be to avoid food or drink from midnight the night before surgery.
Anesthesia medications can cause stomach upset. The best way to prevent after effects from anesthesia will be to avoid food or drink from midnight the night before surgery.
No. Patients can eat whatever they want.
No. Patients can eat whatever they want. Advance your diet from liquids to soft food to solids as tolerated. Please drink as much fluid as you can which will help you from becoming dehydrated.
Cataract surgery cannot be done with a laser by any surgeon at this time. Cataracts are removed surgically by phacoemulsification method. The YAG laser is used only to treat “after cataracts” but not to remove the cataracts.
Any time a foreign object is placed in the eye; there is an increased risk of problems. Therefore, it is highly recommended that you follow your eye doctor’s instructions about caring and cleaning of your contact lenses and see your eye doctor for regular follow-up exams. Contact your eye doctor, if you experience any problems such as unexplained eye discomfort or pain, redness of the eye, watering eyes, or decrease in vision.
Most of the time there is no visible scar after the healing is complete. Incisions in the eyelids are made following natural skin folds and creases. Once healed, the hairline scars will fade, leaving a very inconspicuous incision line that becomes virtually unnoticeable after the healing.
Most of the time there is no visible scar after the healing is complete. Only the lesion itself is removed, leaving a flat raw non-bleeding surface, which is no bigger than the surface area of the original lesion. This causes very little damage to the surrounding tissues allowing rapid healing and minimizing the risk of scarring. Seven to ten days later, wound heals to leave a flat layer of new skin, which gradually blends, into the normal skin color.
Most of the time there is no visible scar after the healing is complete. Once healed, the hairline scars will fade.
Yes. In summary there are four main types of glaucoma:
Children should have their first eye exam at about age three. A child’s eyes finish developing by the age of 8-9 years. Always have a child’s vision checked if there is any doubt about how well he or she sees. Early detection of eye problems can sometimes prevent significant damage to the eye or to vision. If any member of your family has eye problems, then it’s best to have your child’s eyes tested at an early age.
Parents should have their children’s eyes checked at three important stages during their early development: (1) when the infant is about 6 month old. A pediatric ophthalmologist makes sure that the eyes are working well together and there are no rarely occurring but significant defects, such as cataracts and tumors that could threaten the child’s vision; (2) between the ages of 2 and 3, before a child enters preschool. A pediatric/general ophthalmologist at this time checks for any signs of developmental disorders, including lazy eye, crossed eyes (strabismus), nearsightedness, farsightedness, and astigmatism. If a problem is found, effective therapy can usually begin immediately; (3) between the ages of 5 and 6, before the child enters kindergarten. Eye doctor now tests for sharpness of vision and corrects deficiencies by prescribing eyeglasses. A child’s eyes finish developing by the age of 8-9 years.
Early detection of eye problems can sometimes prevent significant damage to the eye or to vision. If any member of your family has eye problems, then it is important to have your child’s eyes tested at an early age.
No, lenses should not be worn for longer than the recommended wearing period to stop discomfort, dryness, blurred vision and allergic reactions that can result from a build-up of protein and lipid deposits on the lenses.
Absolutely not. Never wear a lens that is obviously damaged, even if it feels all right. It could be causing damage to your eyes that might not be immediately apparent. In addition, never wear a lens, which is uncomfortable, causing pain or leaves your vision hazy or distorted.
No, you will not be able to drive yourself. Someone will need to drive you home after your surgery. Someone will need to drive you back to our office for your first postoperative appointment.
Yes, you will be able to drive yourself. But if you require Valium, you should arrange for a ride.
No, you should not drive yourself. Someone will need to drive you home after your surgery and stay with you overnight. Someone will need to drive you back to our office for your first postoperative appointment.
No, you should not drive yourself. Someone will need to drive you home after your surgery. Someone will need to drive you back to our office for your first postoperative appointment.
Generally speaking, you should not swim in your contact lenses. This is for two main reasons. Firstly, it is very easy for the lenses to be washed out of the eye by a small wave or if you place your head under the water. Secondly, the lenses, especially the soft ones, will absorb chlorine or microorganisms from the water. They will then stay in or on the lens for several hours, irritating the eyes and possibly causing infection. Exposure to pool water may also cause contact lenses to adhere quite firmly to you eyes. If this occurs, leave the lenses in the eyes until the natural tears replace the pool water.
You can get readymade watertight prescription swimming goggles that are safe for swimming. For those involved in active water sports should seriously consider LASIK surgery for vision correction.
Most patients undergoing LASIK prefer to have both eyes treated on the same day. There are pros and cons to this approach but most people would like to minimize any postoperative discomfort and time off from work. This is entirely up to the patient. PRK is not performed on both eyes the same day, and a waiting period of approximately two to three weeks is recommended. This is an issue that should be discussed with your surgeon.
Your surgeon will show you how the crease can be created on your eyelid, and discuss with you where you would like it to be placed. The final decision is yours, together with what Dr. Tandon feels would work well with your own eyelid shape.
Yes, contact lenses are an excellent option for sports and work out enthusiasts. They may also improve your peripheral vision, depth perception, hand/eye or foot/eye coordination, and increase your overall performance. Unlike glasses, contact lenses are more stable and flexible. They don’t steam up from perspiration, don’t smudge and don’t fog up if you go from cold to warm temperatures. Contacts don’t slide down, or fall off even during vigorous movements. Contact lenses also make it easier for you to wear protective safety goggles.
No! Never try to wear contact lenses that were not prescribed to you directly. Even if the lenses are cosmetic or colored lens with no power (plano) you should not share lenses with anyone else. Also, sharing contact lenses can promote the spread of eye disease. Never allow anyone else to wear your lenses.
Yes, but remember that only extended wear lenses are designed for this purpose.
With the eye guard taped in place, you can sleep on either side. If the guard is off try to sleep on the opposite side.
Absolutely not. Soft lenses will turn into “corn-flakes” and pop when you touch them. Hard lenses should also be stored in a soaking disinfecting solution to reduce lens contamination.
No. Home-made saline is not sterile and there is the risk of bacterial or parasitic contamination. Although extremely rare, the resulting infection can be so damaging that it simply is not worth the risk.
Absolutely not. This can result in infection. Temporary storage in saline is OK, but the lenses will need to be cleaned and conditioned by soaking in an appropriate disinfecting solution prior to use.
The low humidity in airplane cabins causes dry eyes and contact lens discomfort. It may help to put lubrication drops in your eyes before you enter the aircraft or during the flight. If discomfort continues, it is probably easiest to wear eyeglasses when flying.
No, you cannot use your eyeglass prescription to order your contact lenses. Contact lens prescription and eyeglass prescription are different. It should be noted that the power of a contact lens would not necessarily be the same as that of a spectacle prescription due to the optics of a lens being closer to the eye. A contact lens prescription differs from a spectacle prescription primarily by the addition of lens parameters such as diameter of the lenses, the base curve, the type of material of the contact lens, and the design or manufacturer’s name. If these measurements are not taken by an experienced eye care professional, your contacts may not feel comfortable. Thus, before you can order contacts, you must first undergo a contact lens fitting exam. Doctors charge an additional fee for this fitting exam.
LVC fees can be covered by medical flex / cafeteria plans that allow pretax dollars to be set aside. We encourage you to explore if a medical reimbursement account (i.e. medical flex / cafeteria plan) is offered through your employer. This is a popular way to help pay for your LVC. Money set aside in a medical reimbursement account can often be a significant pre-tax savings. Schedule a free screening now to confirm if you are a candidate for LVC so you are ready to apply for your medical reimbursement savings account.
No, if you have plastic lenses in your glasses then dry tissues will scratch them. It is generally better to dampen the tissue, or even use soapy water and a soft cloth. Glasses with anti-reflective coating should be cleaned with a special cloth and spray.
If you were able to wear contacts prior to surgery, you should be able to wear contacts afterwards. There may be some increase in difficulty due to the new shape of the front of the eye; however, it is very unusual for patients to require significant corrections after surgery.
Yes, but the refractive surgery will have change the curvature of your cornea, requiring a more specialized lens than normal. It is best to consult your eye doctor.
Yes. Try to avoid getting makeup on your lenses. Always insert your lenses before applying eye shadow, eyeliner, and mascara.
Yes, IntraLase is more likely to make corneal flaps successfully in such people.
Yes. If a child is more than 3 years old, lens implant can be considered. The lens power may not be calculated very precisely in children because of the growing age.
No, the best patients are those who are healthy, psychologically stable and well motivated. Patients with significant eye problems like glaucoma or dry eyes may not be eligible. Uncontrolled high blood pressure or thyroid disease is also of concern. If you are on a blood thinning medication, you are not a candidate for eyelid surgery. Through consultation and examination, we can determine if you’re a candidate for this rewarding procedure.
No, the best patients are those who are healthy, psychologically stable and well motivated. Some medical conditions may increase the risk of cosmetic radio-surgery. Through consultation and examination, we can determine if you’re a candidate for this rewarding procedure.
No, the best patients are those who are healthy, psychologically stable and well motivated. Some medical conditions may increase the risk of pterygium surgery. Patients with significant eye problems like glaucoma or dry eyes may not be eligible. Uncontrolled high blood pressure or thyroid disease is also of concern. Through consultation and examination, we can determine if you’re a candidate for this rewarding procedure.
No. None of the current LVC procedures can correct presbyopia. If you are presbyopic, monovision is an option to help correct both your distance and near vision. The monovision procedure corrects the focus of one eye for distance vision and the other eye for near vision. Monovision is a compromise of both distance and near vision. Depth perception is also affected. For people with high visual demands like sports or constant near work (i.e. reading), we recommend full distance correction, and glasses for near vision. A trial period with contact lenses or glasses may help determine if monovision would be a good option for you.
No, nothing can be done to prevent floaters. Floaters can be a nuisance if they continue to appear in your field of vision. You can try moving your eye around (looking up and down) to move them out of the way. Most floaters will fade over time. If they bother you a lot when you read, try turning down the light or blinking. This usually helps.
Sometimes, a cataract should be removed even if it doesn’t cause problems with your vision. For example, a cataract should be removed if it prevents examination or treatment of another eye problem, such as age-related macular degeneration or diabetic retinopathy. Under such circumstances, your cataract surgery is a medical necessity.
Possibly yes. Colored objects are frequently used in teaching and learning processes. If you know that your child has difficulty in identifying certain colors, it will be a good idea to inform your child’s teachers accordingly.
Generally, color deficient people are not denied a driving license. However, remember that a person with color blindness may drive through a red traffic light and cause a fatal accident. Driving laws in certain places are more strict and may limit color blind people from driving heavy commercial machinery.
It depends upon the kind of job you do. Certain jobs, such as printing inks, textiles, and paints etc. require a precise perception of color. Because of your limited ability to recognize colors accurately, your performance at these jobs may be affected.
No, if you follow all prescribed steps for inserting, removing and caring for them. Contact lenses are a safe and effective vision correction device. As a contact lens wearer, you should see your eye doctor on a regular basis to ensure good corneal health.
Generally not. With normal use, contact lenses will stay firmly in position. However, they can come out under certain conditions. High winds can cause the eyes to water and pull the eyelid tight against the eye, increasing the chance of lens loss. A sharp blow to the head may dislodge rigid gas permeable lenses. And rubbing your eye carelessly may result in a lost lens.
No. There is no place for it to go. There is a thin, transparent membrane, called conjunctiva that covers the sclera (white part) and inside of your eyelids is well attached to the sidewalls of the eye socket. This forms a seal which prevents contact lenses (as well as dust and other ‘foreign’ material) passing to the back of the eye.
No, the cosmetic radio-surgery will not be able to achieve all of this.
Yes. This is the most important sign of diabetic retinopathy. In early stages, the bleeding is very minimal, in the form of small aneurysms. These areas may leak. In later stages, the retina loses its blood supply and new blood vessels grow. These new blood vessels are very weak and cause bleeding inside the eye.
Yes. Uncontrolled blood sugar can result in cataract formation.
Yes. If new vessels start growing in the angle (drainage area for the eye fluid), a type of glaucoma called “neovascular glaucoma” develops. This is very difficult to manage.
Yes. Bleeding and then scarring inside the eye results in retinal detachment due to traction.
Yes. End result of uncontrolled diabetic retinopathy is permanent blindness.
You can train your eye muscles to work better together and correct problems like strabismus crossed eyes which involves training the muscles that align the eye.
If drooping of your eyelids is interfering in your field of vision, the blepharoplasty procedure may be covered as a “medically necessary” surgery. Before surgery, your ophthalmologist will perform a comprehensive eye examination. Photographs are often required by insurance companies before surgery to determine if the procedure is medically-necessary. A visual field exam may be ordered to determine the extent to which the upper lid is interfering with your vision. Final decision is made by your insurance carrier after reviewing your condition. Lower eyelids are not covered by insurance unless there is a deformity. Patients should check with their insurance carrier about their coverage. As a general rule, insurance does not cover cosmetic surgery.
No, the blepharoplasty surgery will not be able to achieve all of this. As the skin tightens, many wrinkles go away. Some fine ones may not. Dark circles under the eyes may improve a bit if this is related to large bags, but most often the dark appearance of the lower eyelid skin remains.
No. Currently, there is no way to transplant a whole eye. However, corneas have been successfully transplanted for many years.
Not by themselves. However, floaters and flashes can be related to retinal detachment or a variety of vascular conditions such as diabetic retinopathy, which can result in blindness if not treated.
As a rule, damage caused by glaucoma cannot be reversed. Treatment often can control it. This makes early diagnosis and treatment important to protect your sight.
Yes, contact lenses provide excellent vision for most sports. However, they should also use polycarbonate sports safety goggles or glasses when participating in sports.
Yes! “Snow blindness” and a welder’s flash are examples of “sun burned” eyes. Outdoor enthusiasts and those with sensitive eyes should always wear sunglasses with an ultraviolet filter to block harmful UV radiation from the sun. Contact lens wearers are especially sensitive to bright light. You should always wear a good pair of non-prescription sunglasses with the contacts when outside.
If pterygium is interfering in your field of vision, the procedure may be covered as a “medically necessary” surgery. Before surgery, your ophthalmologist will perform a comprehensive eye examination. Photographs are often required by insurance companies before surgery to determine if the procedure is medically necessary. Final decision is made by your insurance carrier after reviewing your condition. Pingueculum surgery is not covered by insurance unless there is a medical necessity. Patients should check with their insurance carrier about their coverage. As a general rule, insurance does not cover cosmetic surgery.
Yes. Early diagnosis and proper treatment is recommended to restore your vision. A small tear in the retina can be treated by laser or gas (Pneumatic Retinopexy). These procedures are in-office procedures. For larger detachment, a scleral buckle procedure is recommended. This procedure is done in a surgical center.
Yes, even a slight blockage of the vision caused by partial retinal detachment can result in blindness if not treated right away.
Sometimes it is easier to match the eyelids if both are operated. You must be examined before our surgeon can answer this question for you.
Yes, the seg height can be raised either by bringing the nose pads together or by adding a pantoscopic tilt.
Unlike other refractive errors (myopia, hyperopia, and astigmatism), presbyopia is caused by changes in the optical lens.
Yes. Continue with your drops on the other eye as usual.
Yes. Though contact lenses provide benefits, you should still keep your glasses’ prescription current. There may be days that you don’t want to wear your lenses, or when your glasses are better suited for the situation.
Yes, an eye exam is needed to determine the right contact lens fit for you. Because contact lenses are medical devices, they need to be properly fitted by an eye doctor.
Yes, you will need to discontinue wearing contact lenses prior to pre-operative evaluation as well as laser vision correction procedure. Contact lenses can “warp” the corneal surface, which changes the corneal curvature and leads to a refraction that is not representative of your true refraction. In order to properly calculate the treatment to correct your refractive error, you will have to stop wearing contact lenses at some stage prior to surgery. The time interval that you must go without wearing contact lenses depends on the type of lens that you use and the length of time you have used them. Exceptions to these rules exist and you should discuss this with your laser surgeon.
Yes. The single best way to protect your vision is through regular professional eye examinations. Eye care professionals do more than provide eye exams, they care for the overall health of your eyes. This is especially important for contact lens wearers because the contacts could be causing damage to your eyes without necessarily causing any obvious symptoms. You should see your eye care professional regularly.
Flashes will almost always go away completely. It usually takes about a month, but sometimes it can take up to six months. Floaters will gradually get smaller and less noticeable as the weeks and months go by, but usually they never disappear completely.
No. They do not need to because the material itself allows oxygen to diffuse through it making water irrelevant.
Only if the detachment is due to a successfully treated medical condition such as toxemia of pregnancy or rare forms of eye inflammation.
There is evidence that sunlight exposure plays a role in certain eye diseases, such as cataract, macular degeneration, pterygium, and eyelid cancer. It is a good idea to wear sunglasses with protection against ultraviolet light. Patients with or at risk for macular degeneration may also benefit from lenses which block blue wavelengths, such as yellow or amber lenses.
Yes, we do. Dr. Tandon regularly talks about her experiences with laser vision correction (LVC) and answers questions about LVC and eye care. You have the opportunity to meet previous patients and ask them how they are doing with their new vision.
In adults, cataract usually causes blurry vision which is reversible if cataract is surgically removed. Rarely, hypermature cataract can induce glaucoma or inflammation in your eye and urgent cataract removal is recommended. If an infant or newborn child has cataract, it can cause permanent blindness. Cataract surgery is urgent in this situation.
For taking your unique fitting measurements, your physical presence is absolutely necessary. We will need to pre-adjust the frame on your face before ordering your glasses.
The fat is removed with the laser through the inside of the eyelid. The upper and lower eyelid surgery can be done together at the same time.
Patients often are concerned about the pressure changes during flying or SCUBA diving after refractive surgery. These pressure changes will not affect your eye or the outcome of your surgery. It is okay to fly at anytime after refractive surgery. The use of non-preserved artificial tears is recommended while flying for perhaps up to 6 months after the surgery. We would recommend waiting at least one month after your surgery for SCUBA diving because of infection from water and possible rubbing or bumping the eye with the mask.
The ophthalmoscope is frequently used to examine both the central and peripheral retina which will detect the presence of floaters and or flashes. The slit-lamp, combining a microscope with a strong illumination, is often used with a hand held lens, allowing portions of the retina to be seen in greater detail. Some patients are given an intravenous injection of fluorescein dye in a procedure called “fluorescein angiography”. The dye which takes only moments to reach the eye, makes tiny blood vessels visible, enabling photographs to be taken for later study.
Light rays are diverged by minus (concave) lenses and converged by plus (convex) lenses.
Find a repeating pattern, like a tiled floor or some wild wallpaper. Hold the sunglasses a few inches from your face, cover one eye, and move the sunglasses slowly up and down, left and right. Look through one of the lenses. If the lines stay straight, you’re holding quality sunglasses. If lines wiggle or waver, your glasses are not of high optical quality and will distort your vision.
Check the vision of each eye by covering alternate eyes with your hand. If the vision is unclear then try swapping the lenses and then recheck the vision.
Find a reflective surface and hold your sunglasses so that you can see the surface through one lens. Rotate the glasses to see if the glare increases or decreases. If the glare decreases, then you know your sunglasses are polarized. Alternatively, try to see an object below the surface of the water through your sunglasses. If you can see the object clearly under water, your sunglasses are polarized.
Another simple way to check the polarization of a lens is by holding the lens over the top of a lens that you know is polarized. A liquid crystal display (LCD) or digital watch is polarized. Hold the lens over the watch on a horizontal plane and rotate it. If the lens is polarized, you will notice the watch display appears darker as you rotate the lens above it. If the lens is not polarized, there will be no visual difference as you view the watch through the lens.
Schedule a comprehensive eye exam with an ophthalmologist. There are simple in-office tests that can screen for defective color vision. These tests typically involve reading colored numbers from a book or arranging colored papers in order or naming colored lights.
Soft lenses will appear as a smooth dish shape when placed on the end of a finger and when the lens is the right way inside. Another test is to add saline, drop by drop to fill the bowl. If the edges begin to curl inwards, it’s the correct way.
If you have diabetes mellitus, your body does not use and store sugar properly. High blood-sugar levels can damage blood vessels in the retina, the nerve layer at the back of the eye that senses light and helps to send images to the brain. The damage to retinal vessels is referred to as diabetic retinopathy.
Very common. Over 70% of the population experiences these problems.
If you have diabetes, you are also at risk for other diabetic eye diseases. Studies show that you are twice as likely to get a cataract as a person who does not have the disease. Also, cataracts develop at an earlier age in people with diabetes. Cataracts can usually be treated by surgery. Glaucoma may also become a problem. A person with diabetes is nearly twice as likely to get glaucoma as other adults. And, as with diabetic retinopathy, the longer you have had diabetes, the greater your risk of getting glaucoma. Glaucoma may be treated with medications, laser, or other forms of surgery.
Not very common. Only 6-8 people out of 10,000 experience retinal detachment. Retinal detachment can occur at any age, but it is more common in midlife and later. It affects more men than women, and Caucasians more than Blacks.
In-depth pre-op exam is the MOST crucial part of your LASIK surgery. The entire laser treatment is based upon the results of pre-op exam. Obviously, the more accurate the pre-op data, the better your visual outcome would be. Don’t let some non-medically qualified staff member perform this exam on you. Other staff members may be involved in your care as well, but there is no substitute for the personal commitment of your surgeon for your care. Remember, at some laser centers, patients see their surgeon for first time on the day of the surgery; not before and never thereafter.
If you want to get rid of your unwanted moles, warts, skin tags, and other skin outgrowths permanently, with virtually no risk of scarring, for a smoother and more youthful appearance with enhanced confidence, you are a candidate for cosmetic radio-surgery.
It depends on your prescription, your eye health, visual need, and your lifestyle. Only a comprehensive contact lens examination can determine if your sight can be adequately corrected with contact lenses. If you work in a dusty environment or exposed to bright, windy conditions much of the time, eyeglasses may be safer and more comfortable to wear.
Typical signs that a lens is approaching the end of its life is hazy vision, discomfort, and lens discoloration and deposits. These can lead to allergies and other complications.
Typically, your vision will decline and the eye may become achy. In a matter of hours the vision may be totally foggy. Call your doctor or seek emergency help. The greatest risk is during the first week.
If you find out that your arms are not long enough to look at the book or newspaper text and you are nearing forty, you may be ready for reading glasses. You’re not alone. This loss of focusing ability can start as early as 35 or as late as 50. It usually stops progressing at about age 60.
The color choice is up to you. In general, choose colors that complement your hair and skin tones. You can choose one color or several colors to be worn all day, every day or simply for special occasions.
Depending upon your visual needs, you may or may not have all of the following items on your prescription:
In most cases, the most important parts of the prescription are the Base Curve, Diameter and Sphere power.
Cover the other eye to determine if vision is still clear from the eye where you suspect that you have lost the lens. If vision is blurred then more than likely the lens is either dislodged from the cornea or has fallen out of the eye.
Your iris is colored, but does not affect the color of things you see. Enhancer tints highlight a wearers existing eye color and come in a variety of colors including aqua, blue, green, brown, amber and violet. Opaque tints cover the natural color of the iris, making the eye appear a completely different color (such as blue over a brown iris). The wearer sees through a clear area in the center of the lens while showing the world a different eye color.
When someone complains of the appearance of the upper eyelids, the first thing we do is evaluate whether the problem is excess skin in the upper eyelids, or if the eyebrows have lowered in position over time. If the eyebrows are in good position, then we can perform the upper eyelid surgery to remove the excess skin. If the eyebrows are particularly low, the doctor raises the patient’s forehead skin by hand to an appropriate level. If most of the upper eyelid skin disappears, a patient would most likely benefit from a forehead lift.
Bifocal segment height is measured from the bottom of the lens to the margin of the lower eyelid.
Progressive segment height is measured from the bottom of the lens to the center of the pupil.
IntraLase laser beam places a series of computer-controlled, tiny (3-micron-diameter) bubbles within the central layer of the cornea. This pattern results in a precise corneal flap at a depth and diameter determined by the surgeon. As with a mechanical microkeratome, a small section of tissue at one edge of the flap is left uncut, forming a hinge that allows the surgeon to fold back the flap and reshape the corneal bed with the Excimer laser.
The laser software is capable of treating the cornea in an elliptical fashion to correct the astigmatism.
Because retinal tears and detachments are not visible from the outside of the eye, only a comprehensive eye exam can detect them. Your eye doctor will use a light magnification instrument to view the inside of your eye. Your eye doctor may also use certain types of magnification lenses, a slit lamp or ultrasound to diagnose retinal tears or detachments.
Before surgery, your ophthalmologist will perform a comprehensive eye examination. Photographs are often required by insurance companies before surgery to determine if the procedure is medically necessary. Final decision is made by your insurance carrier after reviewing your condition. Lower eyelids are not covered by insurance unless there is a deformity. Patients should check with their insurance carrier about their coverage.
Cataract surgery improves quality of life of people by increasing their independence through improved vision; the ability to drive, work, watch TV, and walk safely.
In many people, increased pressure inside the eye causes glaucoma. In the front of the eye is a space called the anterior chamber. A clear fluid flows continuously in and out of this space and nourishes nearby tissues. The fluid leaves the anterior chamber at the angle where the cornea and iris meet. When the fluid reaches the angle, it flows through a spongy meshwork, like a drain, and leaves the eye. Open-angle glaucoma gets its name because the angle that allows fluid to drain out of the anterior chamber is open. However, for unknown reasons, the fluid passes too slowly through the meshwork drain. In Angle-closure glaucoma, this drain is narrow or closed. As the fluid builds up, the pressure inside the eye rises. Unless the pressure at the front of the eye is controlled, it can damage the optic nerve and cause vision loss.
Both PRK and LASIK are possible and effective for correcting hyperopia. The procedure is identical to the myopic (nearsighted) procedure, however by blocking the laser from treating centrally and allowing it to remove more tissue in the periphery of the cornea, a steepening rather than a flattening of the cornea is produced.
In laser vision correction (LVC), complications rarely occur. These complications can be greatly reduced by the surgeon’s dedication, training, and meticulous attention to details. It is crucial to select your surgeon wisely. Our goal at NeoVision is to communicate clearly to our patients what they can expect during their laser experience, and what their results are likely to be. LASIK Gimmicks
Healing time, stability, and post-operative pain are all significantly less with LASIK. PRK may result in haze, which could be temporary.
A: Laser vision correction (LVC) by NeoVision is very different than at many other laser centers. When comparing laser centers, you should carefully consider all aspects of the LVC surgery, such as the pre- and post-operative care, the dedication of the surgeon, and the laser equipments used. To help you understand this difference, NeoVision has produced a brochure titled “Marketing Gimmicks”. We strongly encourage you to read this brochure carefully so that you are able to choose your LASIK team wisely.
In summary, NeoVision provides an honest assessment for your eligibility, the best surgery, quality follow-up care, and a fair price. We are very proud of our surgical protocols, surgical techniques, and state-of-the-art technologies. Remember! Decisions you make about your LASIK team will ultimately determine how well you will see day after day, for the rest of your life.
Initially, a full correction of eyeglasses is given. If this cannot improve the vision then strong eye is patched until the vision in weaker eye is improved. If strabismus is not improved, eye muscle surgery is recommended to align both eyes to prevent amblyopia. It is vital to the correction of amblyopia that treatment begins as early as possible. A child’s nervous system continues to develop through infancy and can only be corrected during this sensitive period. Doing nothing and waiting will only cause permanent, irreversible damage.
Most people think that they have glaucoma if the pressure in their eye is increased. This is not always true. High pressure puts you at risk for glaucoma. It may not mean that you have the disease. Whether or not you get glaucoma depends on the level of pressure that your optic nerve can tolerate without being damaged. This level is different for each person. Although normal pressure is usually between 12-21 mm Hg, a person might have glaucoma even if the pressure is in this range. That is why an eye examination is very important.
Glaucoma is a disease that results in the damage of optic nerve due to high eye pressure. A person may lose peripheral vision due to nerve damage. This loss of vision is permanent and cannot be regained. In contrast, cataract can cause loss of vision which can be regained by successful cataract surgery. Sometimes, cataract and glaucoma can occur together in the same eye.
Cosmetic radio-surgery is usually performed by giving small local anesthesia injection to numb the skin outgrowths. Generally, there is no pain during surgery. If you are very nervous, you will be given a Valium pill to help you relax. Patients are awake during surgery. Patients do not hear or feel anything and are comfortable during surgery. Radio-Surgery is commonly done in a doctor’s on an outpatient basis.
Eyelid surgery is usually performed by giving small local anesthesia injection to numb the deeper tissues. Generally, there is no pain during surgery. If you are very nervous, you will be given a Valium pill to help you relax. A light intravenous sedation is also given. Patients are awake during surgery. Patients do not feel anything and are comfortable during surgery. Eyelid plastic surgery is commonly done on an outpatient basis. Intravenous sedation is a type of anesthesia; therefore all patients must have a responsible adult to stay with them through the night following surgery.
Pterygium surgery is usually performed by giving small local anesthesia injection to numb the tissues. Generally there is no pain during surgery. If you are very nervous, you will be given a Valium pill to help you relax. A light intravenous sedation may also be given. Patients are awake during surgery. Patients do not hear or feel anything and are comfortable during surgery. Pterygium surgery is commonly done on an outpatient basis.
This varies according to the cleaning and disinfection routine that you use before storing the lens. For specific details, consult the package insert of your lens care system.
It depends on the patient. A young, healthy person with no apparent problems will take about 20 minutes. Someone older, perhaps with high blood pressure, diabetes, glaucoma or other ailments can take much longer. Your eye doctor will determine what tests are needed to provide the correct information for new glasses or contact lenses.
It depends upon you and the type of lens. People with dry eyes may have greater difficulty adjusting to and wearing contact lenses. Soft contact lenses usually take only several days to a week. On the other hand, hard contact lenses may take several weeks to two months before they can be worn comfortably. At first, contact lens wearers may experience some scratchiness, redness, tearing, sensitivity to light and occasional blurred vision.
The total screening may take from 30 to 45 minutes. Dr. Tandon is very careful in deciding which patients are good potential candidates for laser vision correction (LVC) and she educates each patient about the expected outcome and inherent risks associated with laser surgery. She will advise you on the treatment option that is best suited to your eyes, whether it is LASIK, CustomLASIK, IntraLase, PRK, or no surgery at all. Remember, many serious problems occur when people who should be medically disqualified are given the surgery anyway.
Once you are comfortably positioned beneath the laser, it takes approximately five to seven minutes per eye to complete the procedure from start to finish. The actual laser treatment time takes just 15-90 seconds, depending on the degree of correction required. Total time at the laser center on the day of the procedure will be about an hour.
Your LASIK surgeon, Dr. Tandon, will examine your retina and optic nerve, as well as perform a detailed corneal study. The total consultation may take from 60 to 90 minutes. Please bring someone to drive you home afterwards, as it is not safe to drive for several hours after your pupils have been dilated.
The length of surgery depends on several factors including the complexity of each person’s pterygium. Usually, surgery takes about half an hour.
Surgeon spends about half an hour with you discussing where the crease should go. The length of surgery depends on several factors including the complexity of each person’s eyelids. Usually, surgery takes about an hour.
We ask you to arrive at the center half-an-hour before surgery and stay until you are ready to go home. The whole procedure generally takes about two to three hours for upper and lower eyelids.
Although it may vary from State to State, normal regulations maintain that you should see your eye care practitioner every year to update your prescription and maintain good eye health.
Use the eye drops for at least a 3-4 weeks in tapering dose as instructed by your eye doctor.
Usually, patients look normal after about two to three weeks of surgery. Some patients heal faster, and others take longer. However, at two weeks you know you are well on the way to recovery.
Usually, patients look normal after about two to three weeks of surgery. Some patients heal faster, and others take longer. The crease is high just after surgery, and gets lower as the swelling resolves. You will look better at six weeks and even better still at six months. Final results are evaluated at one year. However, at two weeks you know you are well on the way to recovery. After three months, most patients have about 90% of their final result.
The vision correction is permanent. However, your vision may change naturally with time and LASIK does not affect visual conditions that may develop with age. Also, the Excimer laser permanently reshapes the front of the cornea by removing small amounts of tissue typically less than the thickness of a human hair. This tissue that is removed does not grow back thereby making the correction permanent.
All patients require visits the day after surgery, one week, one month, three months, six moths, and twelve months after surgery. Routine annual exams are always recommended, whether or not you have surgery done, to make sure that your eyes are healthy.
For most cases, the thickness of the layer removed by the laser is less than the thickness of a human hair. Actual thickness of layer depends upon the treated correction.
Most refractive surgeons now believe that -12D is the upper limit for good patient satisfaction, although LASIK can be used effectively under certain circumstances for prescriptions as high as -15D. Above these levels, other procedures involving the implanting of lenses inside the eye will probably become the procedures of choice. PRK is also approved by the FDA for treatments of high myopia. However, most surgeons prefer LASIK to PRK when treating more than 4D of myopia. Corneal thickness measurements are very important and this also limits the amount of correction that is performed. People previously “disqualified” based on the corneal thickness may now be eligible for LASIK with the IntraLase laser.
Most people can return to work the next day. This is due to the fact that most people see well enough to drive the day after surgery.
The recommended life of contact lenses varies depending on the type of lenses, from 1-day, 1-week, 2-weeks, 1-month, and longer. With any contact lens, you should follow the prescribed wear and care instructions that include guidelines for replacement.
It depends on your age. Annual comprehensive eye examinations are recommended for adults, contact lens wearers and children starting as early as age two. It is very important that children be examined before preschool since a visual condition could exist that could eventually impair a child’s vision if not detected early and treated. In addition to routine eye exams, you should have your eyes examined by an ophthalmologist if you have:
All surgeries have some risks. If performed by a competent surgeon, complications are infrequent and minor. The vast majority of these operations go perfectly well with excellent results and happy patients. All patients will experience some scratchy sensation for a few days after the surgery.
Any surgery has some risk of bleeding and infection. Wound disruption and heavy scarring are also possible. These are very rare in this surgery, and other complications are even less common. For some of these complications, a touch-up procedure might be necessary for correction. Dr. Tandon will discuss any possible risks with you before surgery is done, and answer all of your questions.

All surgeries have some risks. If performed by a competent surgeon, complications are infrequent and minor. The vast majority of these operations go perfectly well with excellent results and happy patients. All patients will experience some bruising and swelling for a few days after the surgery. The risk can include creases that do not form where they are planned, and can be too low or high, or not deep enough, or not exactly the same in both eyes. In addition, a temporary problem with closure of the eyelids is usually seen. Some may have temporary blurring of their vision, usually due to the ointments applied to the incisions post operatively. Any surgery has some risk of bleeding and infection. Wound disruption and heavy scarring are also possible.

The first step is to contact NeoVision Eye Center to schedule a complimentary personal vision assessment to determine if you are an appropriate candidate for laser vision correction and CustomVue. A WaveScan measurement will be taken to map the unique characteristics of your vision. The surgeon will assess several criteria including level of correction, and overall eye health and discuss the benefits and risks of the procedure. After considering the benefits of CustomVue and discussing your options with your LASIK surgeon, you will be in a much better position to decide if CustomVue Wavefront guided LASIK is right for you.
Clean your lenses daily either in running warm water or with a special lens cleaner. For drying, use a soft cotton cloth or special eyeglass cleaning cloth. When not in use, always store your glasses in their protective case. Never place them face down on their lenses. Always use both hands while putting on or taking off your glasses.
As soon as you see well enough to be confident, are alert from medication, and you are comfortable in the lighting of the day or night.
You can resume driving as you feel comfortable with your vision. About 90% of patients are able to drive on their own on the day following LASIK. With PRK, it usually takes about 4-5 days to feel comfortable. You should avoid driving while under the influence of any medications taken following surgery.
Your old glasses may be adequate at first. You won’t harm the eye by wearing old glasses. After a couple of weeks the eye may be ready for testing and preliminary lens replacement. However, if you wait until about 4-6 weeks, refraction will be more stable.
New techniques have significantly reduced healing times. However, each patient’s healing time varies with the type of procedure performed, medical history and physical health. You can expect to go to your work place after a week.
New techniques have significantly reduced healing times. However, each patient’s healing time varies with the type of procedure performed, medical history and physical health. You can expect to go to your work place within a few days if you do not mind looking a bit swollen and possibly bruised. Many patients return to work in a few days wearing glasses. If your appearance is important then you need to take at least two weeks off.

If the second eye is appropriate for surgery, as little as two weeks may elapse between surgeries, that is if it’s convenient for you and agreed upon by your surgeon.
These are some guidelines for resuming your normal activities:
You may resume exercises as you wish. Don’t get sweat in your eyes. Try to keep your hands clean and away from your eyes. Swimming, however, should be avoided for at least two weeks.
You can take shower or bath the day after surgery. Avoid getting soap or water in your eyes.
Some people will see quite well by the next morning. Even with no problems some people will need several weeks of healing for their vision to return to normal.
Your wounds are never patched. After surgery, patients usually spend at least one day resting with their head elevated on a pillow and often apply ice packs to reduce swelling. Some patients report a dull headache and tenderness or discomfort. You may experience some itching sensation during the healing process.
Your eyes will be patched closed. After surgery, patients usually spend at least one day resting with their head elevated on a pillow and often apply ice packs to reduce swelling. Some patients report a dull headache and tenderness or discomfort. You may also experience temporary numbness.

Some patients report a dull headache and tenderness or discomfort. You may also experience bruising and temporary numbness. Later on, you might experience some itching during the healing process.
Immediately following surgery, patients often comment that, although they can see, their sight is similar to opening their eyes under water. This lasts for a few hours, and then dramatically improves the day after surgery, and weekly after that.
You will need to notify DMV that you have had your refractive error corrected with LVC. They will inform you how to go about changing the information on your driver’s license. In the interim we will be able to give you a signed document attesting to the fact that you had the surgery done and your current level of uncorrected visual acuity.
These are the most common symptoms:
Before surgery, your ophthalmologist will perform a comprehensive eye examination. Photographs are often required by insurance companies before surgery to determine if the procedure is medically necessary. The final decision is made by your insurance carrier after reviewing your condition.
No one knows. You should be aware that some agencies or organizations that have physical or visual requirements for participation, governmental or otherwise, including the military, FAA, airlines, fire departments, law enforcement, and possibly others, may at the present or may in the future, decide to impose limitations on various physical conditions including having LASIK surgery or other refractive surgery. NeoVision Eye Center cannot be responsible for keeping current on the legislation of every conceivable organization, either locally or nationally. If there is a particular group that you are either a member of or anticipate the possibility of joining as a member, you must verify the requirements before having such surgery.
Pregnant women with diabetes should get an eye exam in the first trimester because retinopathy can progress quickly during pregnancy.

Dilated eye examination can detect if you are a suspect for a retinal detachment. The back of the eye will be examined with a special ophthalmoscope and with a slit lamp (clinical microscope). Sometimes a special type of contact lens with built-in mirrors is placed on the eye so the retina can be closely visualized. The ophthalmoscope shines a very bright light into your eye. The light will be uncomfortable, but it is absolutely necessary for a careful and accurate evaluation. Many young nearsighted people have thin areas in their retina called “Lattice degeneration.” These areas could be the precursor for retinal detachment. A laser strengthening procedure can be considered to prevent retinal detachment.
A complete eye exam is more than just updating your prescription for glasses or contacts. Your eye examination by an ophthalmologist consists of a series of tests to assess the overall health of your eyes. Your doctor also checks for eye conditions such as glaucoma, cataract, diabetes, hypertension, retinal detachments, etc.
Many people use the computer 8 or more hours every day. There is no way to eliminate eye fatigue, but we can check for several conditions that may be making your eye strain problems worse. Uncorrected hyperopia(farsightedness) and / or astigmatism may contribute to eye fatigue. Also, if you are in your forties, you may be experiencing a focusing problem called presbyopia. Dry eyes can also make the eyes feel more tired when doing extended computer work. Glasses that correct farsightedness, astigmatism, and presbyopia may allow you to use the computer with less eyestrain and more comfort.
If you have dry AMD, you should have your eyes examined by an ophthalmologist through dilated pupils at least once a year. You should also obtain an Amsler grid from your ophthalmologist to use at home. Also check your vision by reading the newspaper, watching television, and just by looking at people’s faces. If you have wet AMD, it is important not to delay laser surgery if your ophthalmologist advises you to have it. You should protect your macula by wearing sunglasses and taking a special vitamin supplement for the eyes. Contact your ophthalmologist regarding the names of these vitamin supplements.
If you’ve had your eyes checked and they are as good as you think, then your doctor will have no objection to you having plain or tinted lenses in a frame of your choice, or contact lenses that can enhance or change the color of your eyes.
You should consider using progressive or trifocal lenses.
Yes. Sometimes people experience discomfort during the peak of their seasonal allergies. If that happens to you, visit your eye doctor. Your doctor may suggest that you simply reduce your wearing time or discontinue wearing your lenses until the allergy symptoms have disappeared. Thoroughly and frequently cleaning your lenses may help reduce allergy discomfort. In addition, never use eye drops that are not made for contact lens wearers when you are wearing your contact lenses.
Possibly yes. Now, there are many new types of soft contact lenses available. Many eye conditions, which were previously corrected only by hard contact lenses, may now be corrected with soft contact lenses. Make an appointment with your eye doctor and get trial samples of soft contact lenses.
There are many kinds of contact lenses available now which will correct astigmatism, both in soft and gas permeable materials. There is a special type of soft lens called a “Toric” lens, which is designed with different curvatures on the front and back to compensate for the astigmatism. They are more difficult to fit and a lot more difficult to manufacture, therefore tend to be more expensive than standard soft lenses but are widely available now, you can even get monthly disposable toric lenses.
You are less likely to be comfortable with contact lenses than someone who has normal eye lubrication. However, you may choose to wear your lenses only occasionally. You can increase the comfort of your lenses by putting eye lubrication drops.

Dry eyes are caused when your eyes do not produce enough tears, or the tears do not have the normal chemical makeup. Your eye doctor can prescribe one or more of the following treatment options: Use of artificial tears provides most patients temporary relief of symptoms. These tears are used throughout the day and are readily available. Lubricating ointments, applied at bedtime, are commonly used for more severe cases. Other treatments include a minor, in-office procedure to insert small plugs (temporary or permanent as needed) in the corner of the eyes. These special collagen or silicone plugs help reduce or eliminate your dry eye problems. This is a painless, reversible procedure that has helped thousands of patients with dry eyes. The plugs work by keeping your own natural tears in your eye longer to overcome your dry eye symptoms. In rare cases, surgery may be recommended.
Your bifocal power needs to be adjusted. Schedule an eye exam with your eye doctor.
Ask your optician to raise bifocal height or consider using progressive lenses.
It could be your long fingernails or you are closing the case on the contacts. Use a thicker lens.
It all depends upon your reading prescription and how much you care about the quality of your reading vision. If your prescription is SAME for both the eyes and there is NO astigmatism, you can use reading glasses off the shelf. Of course, you will be very limited in choice of frame and you will also compromise on the optical quality of lenses.
If you need to be examined for glasses, it is important that your blood sugar be in consistent control for several days when you see your ophthalmologist. Glasses that work well when the blood sugar is out of control will not work well when sugar is stable. Rapid changes in blood sugar can cause fluctuating vision in both eyes even if retinopathy is not present.
Lenses with anti-reflective coating. These lenses cut down glare on glasses and improve appearance of your eyes.

Vision is greatly improved but typically blurry immediately after the procedure. It generally starts to improve once the surface layer of the cornea (epithelium) has grown back, which in most cases takes 3 to 4 days. Vision typically starts to get good within 7-10 days but can continue to be blurry for a number of weeks. For most patients, vision stabilizes within 3 months (some may take 6 months or longer). The healing process varies for each patient, and it is difficult to predict precisely when you will achieve your best visual acuity. However, most patients who have both eyes treated at the same time report that they are able to drive a car safely and resume their normal activities between 3-5 days following PRK.
It will depend upon the size and type of injury. A comprehensive eye exam is needed to fully determine if you are a good candidate for laser vision correction (LVC).
No. The inherited color deficiency does not change with age.
No, the 2 weeks refers to the actual time of wearing, so they can last longer than 2 weeks if you are not wearing them full time.
Very likely. In the case of a posterior vitreous separation, it is very common for the same condition to occur in the second eye within a year. For this reason, and because flashes and floaters are sometimes caused by retinal breaks, both eyes should have adilated fundus exam as soon as possible when flashes or floaters develop in either eye.
Detachment is more likely to occur if the other eye has the condition (such as lattice degeneration) associated with retinal detachment in the first eye. If only one eye suffers a serious injury or requires eye surgery then, of course, the chance of detachment in the other eye is not increased by the event.
Yes, you are at a higher risk of developing glaucoma. Glaucoma can be treated effectively if it is diagnosed in time, so be sure to have a regular eye examination by an ophthalmologist.
No. Retinal holes, breaks, or tears can occur after uncomplicated eye surgery performed at the highest level of excellence.
Yes. It should be noted that a significant number of men and women of all ages elect to have blepharoplasty to achieve a more youthful look and for more comfortable positioning of the eyelid skin.
Yes. It should be noted that a significant number of men and women of all ages elect to have cosmetic radio-surgery to achieve a more youthful look.
Many people underestimate the importance of backup pair of glasses. Under certain situations, it may not be possible to repair or replace glasses within the time you have. Imagine, you are about to leave for a business/pleasure trip or you are already on such a trip and your current glasses break. You will unnecessarily go through a lot of inconvenience and lose precious time. You can also imagine what will happen if a student breaks or misplaces his glasses during the exam period. Always keep an extra pair of glasses for unforeseen emergencies. It is like driving a car with a spare tire.
Yes, the eye is healing and may feel irritated at times. This experience usually clears in 1-3 weeks. Lubrication with artificial tears may help and excessive dryness may be present at first.
Yes. If you cover your one eye, you will lose depth perception. For the same reason, people with one lazy eye (i.e. poor vision in one eye) do not have good depth perception.
Yes, LVC fee is generally tax deductible as a medical expense. For your unique situation, please check with your financial advisor.
There are two concerns related to doing LVC surgery when a woman is pregnant or nursing: 1) There are hormonal changes during this time that could affect the measurements of myopia, hyperopia, or astigmatism. 2) Medications (sedation, pain medication, even eye drops) can be transmitted to the fetus by the mother’s bloodstream or to the baby through breast milk. For these reasons, we strongly advise against refractive surgery while you are pregnant or nursing and urge you to let us know if you are nursing or if you are or could be pregnant. We recommend that you wait at least 3 months after delivering a baby or wait until after your second menstruation period or cessation of lactation before undergoing LVC surgery.
Yes. It should be noted that a significant number of men and women of all ages elect to have pterygium surgery.
A cataract once removed, cannot grow back. However, during cataract surgery the “posterior capsule”, a very thin, clear membrane that wraps around the backside of the cataract is left intact, and eventually this becomes cloudy. This so called “after cataract” can be treated with a YAG laser. This is a painless office procedure, which restores vision in a matter of minutes to patients with “after cataracts”.
Yes, the results of Radio-Surgery are instantly visible and permanent with no necessary down time and only one treatment is required for permanent removal.
The goal is to create a permanent crease. Generally speaking, the benefits of a blepharoplasty are long lasting, and few people need to have the procedure done a second time. Fat that has been removed will not come back. Of course with aging, the skin gets looser and can hang down. The procedure cannot alter or retard the natural aging process. But the crease generally is permanent.
Surgery is the only way to remove a pterygium, but the results can be disappointing. Even with modern techniques, the recurrence rate is often as high as 30 to 40 percent and they tend to come back bigger and faster.
Initial treatment is oriented towards the lowering of eye pressure. First, different types of eye drops are tried. If medicine is not sufficient then laser treatment is considered. The area to be treated is different in OAG versus NAG. When laser does not work then surgery is recommended to open a drainage system in the eye.
The IntraLase flap follows the curvature of the cornea and produces a flap with vertical edges, unlike the edges left by a microkeratome. This difference in flap architecture may reduce the chance of corneal epithelial ingrowth, a potential complication of standard LASIK. IntraLase laser also avoids improper corneal flaps such as partial and “buttonholed” flaps, epithelial sloughing, corneal wrinkles and flaps that are too thick. IntraLase flaps appear to adhere more tightly to the corneal bed at the end of the procedure. Laser-made flaps demonstrate a more aggressive healing response at the edges compared with microkeratome-made flaps.
Recent studies show that more people achieve 20/20 or better vision with an IntraLase flap than with a microkeratome-flap and have a lower incidence of post-operative dry eye. IntraLase patients in the studies also required fewer enhancement(“touch-up”) procedures.
No, there is no medicine, eye drop, vitamin, herb, or diet that is beneficial to patients with flashes or floaters.
No. There is no medicine, eye drop, vitamin, herb, or diet that is beneficial to patients with retinal detachment.
No, there is none. A tall person may need shorter seg height and a shorter person may need a higher seg height.
No, there are no treatments available to correct your inherited color vision problems. Nothing can be done to replace a defective mechanism in your retina. Many color defective people learn how to compensate for this defect in their vision. It is important that good lighting is always available. Many people find limited help in identifying certain colors with the help of a small red or red-mauve filter held in front of the eye.
Yes, there are two ways of writing a prescription for astigmatism. Some prescriptions are written in (-) cylinder and some are written in (+) cylinder. These prescriptions are equal even though they may not appear so.
There is usually no swelling or bruising after surgery. There may be some scratchy sensation but very little and this too fades rapidly. Women can camouflage treated areas fairly easily at seven to ten days with make-up.
There is usually some swelling which gradually resolves after one to two weeks. There may be some bruising, but very little and this too fades rapidly. Women can camouflage bruises fairly easily at seven to ten days with make-up.
Your eye will look very red for about 1-2 weeks after the surgery.
There are different types of lasers used in the management of different eye diseases and disorders. The laser used in the treatment of glaucoma is different from the one used in PRK and LASIK surgery.
Yes. Diabetes can cause severe problems with your sight. It is very important that your eyes are checked every year, preferably with drops to dilate the pupil, so that the retina (back of the eye) can be examined thoroughly.
Light rays passing through the optical center (OC) of a lens are not refracted. With proper PD measurements, your eyes are centered at the optical center of the lens.
Wear the sunglasses when outdoors for about a week. If you prefer you may wear your own sunglasses. There is no need to wear them indoors or outdoors in dim or overcast light.
It should be discussed between the doctor and the parent as to whether the prescription indicates contacts and whether the child is mature enough to follow instructions properly.
Children with this condition may have to be treated with steroids. Eye inflammations associated with this condition are usually treated with long term steroid eye drops. Cataract and glaucoma at the young age may be the result of this treatment. A routine and thorough eye examination is recommended to diagnose and treat glaucoma and cataract in these children.
No. Reading or working under low light does not have a physical effect and is not harmful.
Children have a much better ability to focus close at a younger age than adults. They get a much bigger picture at this distance. In general viewing anything close will not have any effect on physically changing the eyes on anyone. However, get your child’s vision tested by an eye doctor to make sure that he / she does not have a problem seeing far objects clearly.
Sometimes contact lenses ‘hide’ beneath eyelids. If you wear soft contact lenses, they will tend to center automatically on the cornea. If you wear rigid gas permeable (RGP) lenses, you may need to manipulate a displaced lens through the eyelid. In rare instances, an RGP lens may adhere by suction to the conjunctiva. First, apply wetting solution to the lens and wait about a minute. Then try to move the lens while gently pressing on one edge. If that doesn’t work, you can try to very gently lift up under one edge to break the seal. Or go see your eye doctor. If a contact lens adheres repeatedly, it is not fitted correctly and should be replaced.
There are three possibilities (1) tear in contact; (2) increased deposits, or (3) contact is inside out.
It indicates increased deposits on the contacts and/or possible allergic response of upper lids to dirty contacts. Discard the old lenses and use fresh ones.
It is not advisable to wear contact lenses if your eyes are bothering you, particularly if the discomfort is related to contact lens wear.
Wear photogrey, light tint, Transitions lenses, or polarized lenses.
You need frame adjustment. Also, consider lighter lenses such as hi-index or polycarbonate in a smaller frame.
Eyeglasses ordered under an insurance plan are usually processed by the insurance labs and we do not have much control over it. They usually take 5-10 business days. However, if you order your glasses privately (i.e. without an insurance plan) and you need single vision lenses without any special coatings, your glasses can be made ready in 1-2 days.
We usually promise 5-10 business days to process an eyeglass job. The actual time for a particular pair of eyeglasses depends upon a variety of factors including your prescription and lens options you have chosen. Remember, eyeglasses are a custom-product i.e. they are made to your unique specifications. Occasionally, during the process of lens edging and mounting, the frames or the lenses are damaged and the lab needs to start the order all over again. This can add to the overall time to finish a particular job. Eyeglasses with drill mount lenses (i.e. rimless frames) generally take longer.
At NeoVision, we apply stringent quality control standards on each and every eyeglass order. Our opticians inspect every job after it has already been checked and approved by the manufacturing lab. If we notice any defects in the frame or lenses, we will not deliver it to you. Instead, we reorder the frame or the lenses and process the order all over again. While this could add time to your order, you can be assured that the final product you receive from us will be in a perfect condition. Our emphasis is on the finest quality of the final product rather than rushing an order.
It is perfectly natural to be nervous about having the procedure. Your LASIK surgeon, Dr. Shobha Tandon will spend a great deal of time describing exactly what’s involved in the procedure. She will “walk you through the process” to make you as comfortable as possible.
For the first few hours there may be some discomfort, but usually not severe. If the pain persists, call your doctor.

That is why we offer one global comprehensive LVC fee, which includes all pre-operative, surgical, and post-operative care for one year for standard (conventional) LASIK. For optional upgrades such as CustomVue WaveScan andIntraLase, there is an additional charge per eye. Our fees do not change by the prescription, by the laser technology, by the amount of care needed, or by the surgeon. We do not believe in advertising misleading prices.
Floaters are relatively transparent, vague, usually curved objects that you may occasionally see floating in your field of vision. They are seen best when looking at a white piece of paper, blue sky, light colored ceiling, or wall. They sometimes look like cobwebs, worms, circles, lines, clouds, dots, or specks. Eye movement makes floaters more visible as they swirl about like seaweed in the ocean surf. Floaters may seem to “run-away” when you try to look at them.
Flashes, on the other hand, are momentary streaks of light, and could indicate a serious problem such as posterior vitreous detachment or retinal tear. Floaters and flashes are common symptoms that are usually but not always harmless. Both floaters and flashes commonly occur as we grow older.
laser vision correction procedures, cosmetic surgery, or any other surgical procedure requiring payment in advance, can be paid for in a number of ways. NeoVision Eye Center has allied with several lending institutions to offer competitive financing options for our patients. The “Same as Cash” financing option allows you to have the procedure right away and make payments interest free over the next 6 months. You may also apply for the standard financing option. It gives you the convenience of payments that works like a personal loan. You select a term of 24 to 48 months along with the amount you need. Your monthly payments could be less than $50 per eye. Please ask for further details or an application. Applying for financing consists of a very short form, literally taking less than 5 minutes. Interest rates and down payment requirements are solely dependent upon credit rating.
You can order your own custom reading glasses by choosing any of our eye glass frames and adding reading lenses in your unique prescription. You will be able to order glasses with clear prescription lenses or with tinted prescription sunglass lenses with anti-scratch, anti-UV, and/or anti-reflective coating. You will also have a choice of lens materials such as CR-39 plastic, polycarbonate, Trivex, or hi-index.
Keep windows in your home and car closed during the pollen season, use air conditioning instead. If you suffer badly, some cars have filters fitted that remove the pollen from incoming air.
If you have continued problems with your eye allergies, call today at 1-510-431-5511 to schedule an appointment at NeoVision Eye Center.
Infection following laser surgery is extremely rare. However, if it does occur, it is important to catch it early to prevent any damage. Signs of infection include a white spot on the cornea, redness that persists beyond one day, eyelid swelling, pain and discharge. These could all simply be the side effects of surgery. If you are concerned please call our office. Please bring the medications with you on each of your visits. If you have any questions, please call us at 510-431-5511. If you are calling after office hours, please identify yourself to the operator by saying that you are a surgery patient.
There are two types of macular degeneration. A “dry” type that can cause a decrease in your central vision and a “wet” type that can lead to further loss of your central vision.
An IOL is a permanent replacement for your natural lens. After it has been placed inside your eye during cataract surgery, it requires no further care. You probably won’t be able to feel your new lens; and others will not notice it either. An IOL never needs to be handled, adjusted, or cleaned.
Although LASIK and PRK are relatively new procedures, results from U.S. studies to date show that 95-98% of patients with mild to moderate myopia who have undergone PRK have achieved stable 20/40 distance vision or better with one treatment. Although a 1-2% of eyes will lose a line of best correctable vision, no significant long-term sight threatening consequences have been reported in ten year follow-up from international centers.
With prompt medical attention, most of the complications usually can be treated successfully. Possible complications that could occur during surgery include the following:
After laser surgery most patients experience a general scratchiness or foreign body sensation with some tearing. Some pain and discomfort are normal. Sometimes eyelid may be swollen or droop a little. You may be sensitive to bright light for some time. After surgery, keep your eye(s) closed for about two hours, then gently open and start using the drops as directed.
For pain, you can take Vicodin tablet if prescribed. We use three kinds of topical drops post-operatively. One is an antibiotic to help minimize the chance of infection; the second is an anti-inflammatory to help minimize inflammation excess; and the third is a tear lubricant, provided to help the superficial corneal cells remodel and remain moist. The antibiotic and anti-inflammatory drops are used for approximately one week, while the teardrops are used for at least one to three months.
You should start using antibiotic eye drops, Zymar, every two hours for the first day then four times a day for five days. Predforte anti-inflammatory drops, use one drop every two hours for the first day then four times a day for five days. Shake the bottle before use. Preservative-free lubricating drops (Refresh Plus) can be used every hour and as needed for feeling of dry eyes. If you are using all the drops at the same time, use five minutes interval between two drops. To instill the eye drops, pullout lower eyelid and instill the drop gently. Blot dry the excess rolled over drop on your face. Do not rub or put pressure on your eye.
The goal of any refractive surgical procedure is to reduce or eliminate your dependence on corrective lenses so that you may freely enjoy activities without the encumbrance of corrective glasses or contacts. It is very important that your expectations are reasonable and that you understand the possible scenarios in which your expectations might not be met. In general, the higher the myopia and / or astigmatism you begin with, the less likely you are to have an ideal outcome.
Risk factors for retinal detachment include the following:
There are very few inherent risks and complications involved in LVC surgery. In spite of our very best efforts and the best technology, there will be some results that are less than ideal. You must make a decision based upon the best information available whether or not the potential benefits of your contemplated surgery outweigh the risks. Although it is not possible to list every potential risk or complication that may result from the procedure, many of them are described below:
Halos / Starbursts: Some patients will notice glare, halos or starbursts around objects at night or in dim-light conditions. Patients who notice these effects may need to wear glasses to drive at night. For the vast majority, these symptoms are temporary. However, others will continue to experience them for several months or longer. During your pre-operative evaluation, we will determine whether or not you are at high risk for seeing long-term halos. These side effects tend to be less noticeable the closer you get to the ideal correction of your refractive error. Note that CustomLASIK reduces the frequency of glare, halos or starbursts problems following treatment and results in clearer, crisper vision compared to treatments performed by conventional LASIK.
Dry eyes: Increased dryness of the eyes is a common, but generally temporary, complication arising from LASIK, CustomLASIK, IntraLase, or PRK. It typically lasts for several months, though some patients may experience dryness for a longer period of time. It is important to use lubricating drops frequently. If the eyes remain dry for prolonged period, there are other drops or techniques that can help. Patients who have dry eyes prior to the procedure are likely to experience dry eyes after the procedure.
Infection: All eye surgeries carry with them the possibility of infection. This is an extremely rare occurrence, with a 1 in 10,000 treated eyes. Fortunately, as the laser vision correction techniques have developed over the years, firmly established protocols now exist which dramatically minimize the risk of infection. Most infections respond well to antibiotic treatment.
Diffuse Lamellar Keratitis (DLK) or “Sands of the Sahara”: Some patients develop an inflammatory reaction between the flap and the corneal bed, called Diffuse Lamellar Keratitis (DLK) or “Sands of the Sahara.” Patients with DLK may not show any symptoms at all or may experience blurred vision and tearing. DLK can generally be treated with eye drops and rarely results in any permanent impairment of vision.
Retinal detachment: Although retinal detachment is not usually considered a specific complication of laser vision correction surgery, it is at least a possibility. Even without any surgical intervention, myopic patients are always at risk for retinal detachment and LASIK may not alter this risk.
Anesthesia or drug reactions: As with all types of surgery, there is a possibility of complications due to anesthesia, drug reactions, or other factors which may involve other parts of your body. The patient must inform the doctor if they have ever had a reaction to any kind of anesthesia.
Corneal scarring: There are corneal irregularities which can rarely occur. The worst case scenario could be corneal scarring. The risk of corneal haze or scarring is more in PRK than in LASIK.
Equipment malfunction: The microkeratome, IntraLase and Excimer lasers have proven to be very elegant, very dependable devices for creating the corneal flap and reshaping the cornea. Nevertheless, we are working on the cornea which is about 0.6mm thick, and as with any device, the microkeratome, IntraLase, and Excimer laser are not perfect. In spite of out best efforts, there are times when they produce a less than ideal result. We will not begin your procedure unless our equipments are functioning properly. Additionally, we might have to stop at the safest possible point if a malfunction should develop.
Surgical team: The less the experience of the surgeon and team, the greater is the risk. But even with the best available equipment and the most experienced surgeons, complications can and do occur. The only way to avoid all risks of surgery is not to have the surgery done at all. As a generality, the more serious the risk, the less likely it is to occur.
Vascular occlusion: When the suction ring is applied to the eye to create a corneal flap, the pressure inside the eye increases significantly and most patients notice either a dimming or a complete loss of light in the eye. As the suction ring is removed, the vision is restored within a few seconds. There is a less than 1 in 1,000,000 probability that when the suction ring interrupts the blood supply to the eye, permanent damage to the retina and loss of vision can result. Note that unlike microkeratome, IntraLaseemploys a suction ring that uses low vacuum.
Increased pressure in the eye: The drugs used during the first week after surgery, on rare occasions, may cause increased pressure in the eye. This raised pressure needs to be closely monitored and may require additional topical and/or oral medications. It is important for you to return to NeoVision Eye Center for scheduled follow-up visits to monitor your eye pressure in order to modify the medication schedule as needed.
Eyelid droop: The eyelids have a natural tendency to droop with age. The eyelid speculum that is used in the procedure may hasten this process.
Corneal ectasia: A certain minimum amount of corneal tissue must remain under the flap after the laser has achieved tissue removal. The amount of remaining tissue relates directly to the long-term stability of the cornea. Less than optimum remaining cornea may result in bulging, called ectasia. This problem can be avoided by precise pre-operative measurements and creating an optimum corneal flap during surgery.
Improper corneal flap: The corneal flap may be of improper or irregular thickness or incompletely cut. Such problems may require that the procedure be stopped until the surgeon can safely cut a new flap. There is also a small risk that the hinge of the flap may be cut from the cornea (also known as a “free flap”). In most instances of “free flap” the surgeon can still perform the laser treatment. This detached flap is repositioned and covered with a bandage contact lens to promote healing. Note that the IntraLase laser may avoid partial and “buttonholed” flaps, corneal wrinkles, and flaps that are too thick.
Increased light sensitivity and vision fluctuations: Patients’ eye may become extremely sensitive to light and glare after the procedure. Visual acuity may also fluctuate. These conditions are generally temporary and usually go away within 1-3 months
Epithelial defects: The epithelium in some eyes is only loosely attached to the corneal surface. Such eyes are at increased risk for epithelial erosions or defects, especially as the microkeratome passes over the corneal surface. In some cases, this risk is identified before surgery and the patients are advised accordingly. There are, however, occasional patients where there are no pre-operative clues. In addition, older patients are more likely to have occult areas of this weakened skin. Note that the IntraLase laser may better avoid some of the epithelial irregularities and sloughing.
Epithelial ingrowth: Epithelial cells can appear as either “isolated pockets or nests” under the LASIK flap. This may result due to improper healing at the edge of the flap. Most of these are fairly easy to successfully eliminate. Note that the IntraLase flap follows the curvature of the cornea and produces a flap with vertical edges, unlike the edges left by a microkeratome. This difference in flap architecture may reduce the chance of corneal epithelial ingrowth.
Under-correction or over-correction
: The healing response of the eye occasionally counteracts the precisely calibrated removal of tissue by laser. While the treatment of your refractive error is designed to completely neutralize your refractive error (unless otherwise agreed upon with your surgeon) this treatment is based on an average eye’s healing response. If your eye heals differently from the “average”, this may result in an over- or under-correction. A patient’s tolerance for under-correction or over-correction varies. In majority of instances, the over- or under-correction can be corrected with glasses, contact lenses, or additional surgery.
It is important that you understand this possible outcome and accept it as one of the risks of surgery. If this should occur, you will probably be disappointed with your result. Under- or over-corrections are actually the most common undesirable result or complication of surgery. Significant over-corrections occur about 1% of the time.
Re-treatment or enhancements: The vast majority of patients require only one refractive treatment. Due to each individual’s prescription level and unique physiology, however, an additional treatment or enhancement may be required. The additional procedure can involve all of the risks and side effects as discussed before for the primary procedure. As always, this risk should be weighed against the expected or desired benefit. The patient must generally wait at least three to six months after the first treatment and must have adequate corneal tissue and stable vision. Results cannot be predetermined or guaranteed.
At first, open-angle glaucoma has no symptoms. Vision stays normal, and there is no pain. As glaucoma remains untreated, people may notice that although they see things clearly in front of them, they miss objects to the side and out of the corner of their eye. Without treatment, people with glaucoma may find that they suddenly have no side vision. It may seem as though they are looking through a tunnel. Over time, the remaining forward vision may decrease until there is no vision left. Angle closure glaucoma causes severe and acute eye pain, blurry vision, nausea vomiting etc. Often an emergency laser treatment is given to lower the eye pressure.
A sudden increase in number and size of floaters is a warning that small amounts of blood and debris have appeared in the vitreous. The flashes are sensations from the retina as it is pulled or torn, or is rubbed by the loosened vitreous. If a tear breaks a larger retinal blood vessel, the blood spilling into the vitreous can cause a massive increase in floaters or even total loss of vision in that eye. The floaters will usually decrease in a few weeks or months and vision will improve, as long as the retina is not detached.
Most retinal tears do not cause problems and are not especially dangerous. However, if fluid starts to leak through them, the retina will start to peel (like wallpaper) and the detachment process begins. At first, you may have no symptoms, especially if the detachment is off to the side. Later, a “curtain” of darkness will start moving in and block out vision from one direction (the position depends on the location of the detachment). When the peeling process reaches the central zone of the retina (the macula), vision will suddenly and dramatically blur. As time goes on (which could be hours, days, or weeks), the curtain will continue to darken more and more of your vision, until you are left only able to see bright light. If you experience any of these symptoms, contact your ophthalmologist as soon as possible for a thorough evaluation.
Your ophthalmologist can give you instructions on how to treat amblyopia. Children do not like to have their eyes patched. But as a parent, you must convince your child to do what is best for him or her. Your interest and involvement will be necessary for successful treatment.
If you are being treated for glaucoma, be sure to take your glaucoma medicine every day and see your ophthalmologist regularly. You can also help protect the vision of family members and friends who may be at high risk for glaucoma. Afro-Americans over age 40 and everyone over age 60 are at a higher risk of glaucoma. Encourage them to have an eye examination through dilated pupils every one-two years.
Finding and treating the disease early, before it causes vision loss or blindness, is the best way to control diabetic eye disease. Therefore, if you have diabetes, make sure you get a dilated eye examination at least once a year.
Dark circles may be treated by lower eyelid surgery if it results from shadowing due to bulging fat or bags. If the dark circles result from pigmentation changes of eyelid skin, skin bleaching creams or light chemical peels may improve this condition.
A routine follow-up with your ophthalmologist and early and proper treatment is recommended to prevent this blindness. Depending on your initial examination, you may need examination every 3 months to once a year. Along with an eye examination, a good control of your blood sugar is very important.
Normal use of your eyes will not cause further damage to your vision. Even if you have lost sight to AMD, you should not be afraid to use your eyes for reading, watching TV, and other usual activities.
The natural tears that your eyes produce are composed of three layers: (1) outer oily layer, (2) middle watery layer, and (3) inner mucus layer. Dry eyes either do not produce enough tears or have excessive evaporation of tears due to improper chemical composition of the tear film.
As people age, the vitreous humor starts to liquefy centrally, forming clumps or strands inside the eye. The outer portion of the vitreous gel pulls away from the retina, causing a vitreous detachment, causing the brain to perceive flashes of light. People who are nearsighted, have undergone cataract operations, have had YAG laser surgery of the eyes and have had inflammation inside the eye are at greater risk of vitreous detachment. When the vitreous gel which fills the inside of the eye rubs or pulls on the retina, it sometimes produces the illusion of flashing lights. The flashes of light may appear off and on for several weeks or months. On rare occasions, light flashes accompany a large number of new floaters and even a partial loss or shadowing of side vision.
The appearance of floaters may be alarming, especially if they develop suddenly in a person over 45 years of age. An ophthalmologist should be consulted right away if you see sudden flashes of light, or see a curtain or veil obscure your vision. This could indicate a torn retina which is always a serious problem since it can lead to a retinal detachment. While floaters may remain in the vision, many of them will fade over time and become less bothersome. Even if you have had floaters for some years, an ophthalmologist should be consulted if new ones develop.
Retinal detachment is caused by a combination of factors including retinal holes, retinal breaks, or retinal tears, and liquefaction of the vitreous humor. Any tiny tears or holes in the retina can allow vitreous fluid to seep under the retina, separating it from the back wall of the eye (like wallpaper). Retinal tears may also result from a hard blow or injury to the eye, though this is rather rare.
There may be other reasons for visual loss in addition to the cataract, particularly problems involving the retina or optic nerve. If these problems are present, removal of the cataract may improve vision, but perfect sight may not be possible.
Your eyeglass prescription contains information regarding the lens power required to correct your vision problems. It consists of spherical power, cylindrical power, cylinder axis, bifocal addition, and prism power. Your prescription will contain only those numbers that are pertinent for your vision correction, for example, if you do not have astigmatism, you would not have a cylindrical power and axis information in your prescription. Most prescriptions do not contain prism power.
Frames are identified by manufacturer/designer, model number or name, size, and color information. Size information contains the horizontal measurement of each lens in millimeters (i.e. 47) and bridge size (the distance between the lenses) i.e. 18. This information can help you in sizing a frame for your face. To better understand the frame size, double the first number and add the second. This will give you the distance across the full front of the frame. For example, a frame size of 47/18 means that the frame measures 112 mm across (47 x 2 + 18 = 112).
Frame size may also contain the temple length (including the portion going behind the ear) in millimeters such as 145. Therefore a frame size would be written 47/18 or 47-18 or 47/18-145. Color may be noted as a description such as gunmetal, other manufacturers use a color number. NeoVision’s opticians will help you in choosing the right size frame for the best possible fit.
The procedure is called surfacing which involves grinding the back side of a lens.
This refers to the best vision that your eyes are capable of seeing with the best corrective glasses and / or contact lenses. It is generally a reflection of the health of the eyes such as with nearsightedness,farsightedness, or astigmatism. Best corrected vision is measured on the same eye chart as the visual acuity without correction.
It is a measurement of sight. “20/20” vision refers to 8.7mm tall letter that a person with “average” or “normal” vision can see at 20 feet. Someone with 20/40 vision can only be 20 feet away from an object to see what a person with normal vision can see at 40 feet. Similarly, the person with 20/400 vision can only be 20 feet away from an object to see what a person with 20/20 vision can see at 400 feet. Most states require 20/40 or better in at least one eye to get a driver’s license without glasses or contact lens restriction. Note that the term “20/20” does not reveal the quality of vision.

We believe that only the best equipment must be utilized with the best surgical team in order to achieve the best possible results. These machines are meticulously maintained in order to continue to achieve outstanding results.
implementation of Wavefront technology. The system works by bouncing a harmless infrared light off your retina. The reflected beam washes over the internal optical structures of the eye, emerging as a light wave. The shape of this wave, or Wavefront, is compared to that of the optically perfect eye to create a Wavefront error map. This map can be used diagnostically for pre-operative screening and post-surgical analysis, and is also used to generate the surgical plan for Wavefront LASIK treatment on the VISX S4.
For premium surgeries, we use FDA-approved IntraLase laser to create corneal flaps that further minimizes microkeratome-related complications.
It’s normal to feel itching and mild discomfort for a while after cataract surgery. Some fluid discharge is also common, and your eye may be sensitive to light and touch. If you have discomfort, your eye doctor may suggest a pain reliever every 4-6 hours. After 1-2 days, even moderate discomfort should disappear. In most cases, healing will take about 6 weeks.
After surgery, your doctor will schedule exams to check on your progress. For a few days after surgery, you may take eye drops or pills to help healing and control the pressure inside your eye. Ask your doctor how to use your medications, when to take them, and what effects they can have.
Surgery is usually performed on an outpatient basis. The operation usually lasts less than 1 hour and is almost painless. When you arrive for surgery, some eye drops will be instilled to dilate your pupil. Many people choose to stay awake during surgery, while others may need to be put to sleep for a short time. If you are awake, you will have an anesthetic to numb the nerves in and around your eye.
The area around your eye will be thoroughly cleansed, and sterile coverings are placed around your head. Under an operating microscope, a small incision is made in your eye. Microsurgical instruments are used to break apart and suction the cloudy lens from your eye. The back membrane of the lens (called the posterior capsule) is left in place. An intraocular lens implant is placed inside your eye to replace the natural lens that was removed. The incision is then closed. No stitches are used.
After the operation, a patch will be placed over your eye and you will rest for a while. You will be watched by your medical team to see if there are any problems, such as bleeding. Most people who have cataract surgery can go home the same day. Since you will not be able to drive, make sure you make arrangements for a ride.
Cornea has 70-80% of eye’s focusing power.
If you are wearing daily contact lenses, you should always take them out before you go to sleep. If, however, you do fall asleep with them on your eyes, remove your lenses as soon as you get up, and follow the recommended lens cleaning and disinfecting instructions. It may be helpful to put drops in your eyes before removing your lenses to moisturize them.
If you have pierced ears, the way you healed there is a good indication of how you will heal from cosmetic facial radio-surgery. Scars on the rest of the body typically are not an indication for how patients heal following facial cosmetic surgery. At the time of your consultation, it’s important to show your physician any previous scars (called keloid scars) that are of concern so your doctor can give you a realistic assessment of your healing potential following facial surgery. If you have a history of abnormal scarring, there are medications that can be used to help prevent excess scarring.

It is very rare that a second operation is necessary. Rarely, the crease needs to be deepened or lengthened. Your surgeon will advise you on the pros and cons of a touch-up depending upon your unique situation.

Bottle rockets, BB guns, racquetball, tennis, golf, soccer, boxing, and diving injuries can lead to retinal detachment.
UV400 means that the lens blocks all lightwaves 400 nanometers and below. 400 nanometers is typically referred to as the point where UV light starts. Anything below 400 nanometers is considered to be in the ultraviolet range.
WaveScan technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. This technology has now been applied to laser vision correction, measuring imperfections in the eye never before measured using standard methods for glasses and contact lenses. WaveScan-based digital technology identifies and measures imperfections in an individual’s eye 25 times more precisely than standard methods. Like fingerprints, no two Wavefront eye maps are alike. LASIK surgeons use this information to treat individuals with the CustomVue™ procedure.
A diopter is a unit of measurement that is simply the inverse of the focal distance of the lens as measured in meters. For example, if a lens has a strength of 2 diopters, then parallel light rays that pass through this lens will focus together at a distance of 1/2 meter (50 cm) away from the lens.
A lens with no corrective power is called plano.
Retinal detachment is a serious condition that can lead to severe visual impairment or even total blindness in the affected eye. If any part of the retina is lifted or pulled from its normal position, it is considered detached, and will cause some vision loss. The detachment will almost always progress, and vision loss will increase until it is treated. Therefore, retinal detachment is always considered an emergency.
Amblyopia is reduced vision in an eye that did not develop normal sight during early childhood. It is sometimes called “lazy eye.” It can be avoided by having children’s eyes examined between the ages of three and five. Amblyopic eye is normal by examination but it cannot see very well. Visual improvement is possible until 9 years of age.
The Excimer laser produces a high-energy, cold, ultraviolet light beam in pulses and delivers the pulses to a surface of the eye’s cornea. These pulses break the bond between molecules and tissue cells so that a controlled amount of tissue can be vaporized away to reshape the cornea. Excimer laser beams do not disturb the underlying eye structures such as iris, lens, and retina. The Excimer laser is computer controlled and programmed to treat each individual eye with a high degree of precision.
In most cataract surgeries, the removed lens is replaced by an intraocular lens (IOL). An IOL is a clear, artificial lens that requires no care and becomes a permanent part of your eye. With an IOL, you’ll have improved vision because light will be able to pass through it to the retina. Also, you won’t feel or see the new lens.This IOL can be of different material such as plastic, silicon or acrylic. All of these materials are tested for years and do not cause any problem once they are nicely implanted in your eye.
Some people cannot have an IOL. They may have problems during surgery, or maybe they have another eye disease. For these people, a soft contact lens may be suggested. For others, glasses that provide powerful magnification may be better.
Sometimes the thin natural bag (capsule) that supports the intraocular lens becomes cloudy and may blur your vision. This is called an after-cataract. An after-cataract can develop months or years later. Unlike a cataract, an after-cataract is treated with a laser. In a technique called YAG laser capsulotomy, your doctor uses a laser beam to make a tiny hole in the lens capsule to let light pass through. This is a painless outpatient procedure.
Anisometropia is a condition where there is a significant difference in the refractive errors of the two eyes. If this condition is present in infancy and is undetected or untreated, it often results in the development of lazy eye or amblyopia in the weaker eye. The greater the amount of the difference, the more likely the development of lazy eye will be. Another problem can occur when glasses are made for an anisometropic individual. The difference in the powers of the lenses induces a prismatic difference that can cause double vision in off-center areas of the lens, which can be compensated for by the use of slab-off prism.
Automated Lamellar Keratoplasty (ALK) for nearsightedness is a procedure that has been replaced by LASIK in recent years. ALK corrects nearsightedness by removing a thin layer of tissue from the cornea to flatten the eye’s surface. Unlike RK, which flattens the eye by making incisions into the surface, ALK actually removes a thin disk from the cornea, leaving it thinner and flatter than it originally was. The disadvantage of ALK is that it is not nearly as accurate as the Excimer laser for the tissue removal step, so multiple procedures are sometimes needed to achieve the final correction. LASIK is a combination of ALK and PRK.
Blepharoplasty refers to eyelid surgery which is designed to remove the excess fat, along with skin and muscle, from the upper and lower eyelids. It is the second most common cosmetic procedure performed with about 50,000 persons having the procedure in the United States each year.
Color blindness, more accurately called color deficiency, is a term used for a deficiency in recognizing certain colors. Most color perception defects are for red or green or both. Another form of color blindness; yellow-blue is the second most common form, but it is rare and could be a result of some optic nerve disease. Complete color deficiency, where all colors are seen as varying shades of black and white is almost unknown. About 10% of males have a color perception defect, but this is rare in females.
If there is no value under the cylinder heading, then you have a simple prescription. If there is a value under this heading, then you have astigmatism. Like sphere power, the cylinder power is also measured in diopters.
Inter-pupillary distance (PD) is the distance from the center of the pupil in one eye to the center of the pupil in the other eye. A PD measurement ensures that the center of the lenses line up with the center of your pupil. Before your prescription lenses are cut into the shape of your frame, the pupillary distance needs to be measured. This measurement is then used so that the optical center of each lens can be lined up with your pupils in order to give optimal visual clarity.
PD measurements for distance and near vision are different, like 62/59, the first number is your distance PD and the second is for your near PD (for reading-only glasses). For people with asymmetric eyes, PD measurement for each eye is done separately (called “monocular PD”), like 30.5/31.5. The first number is for the right eye (O.D.) and the second number is for the left eye (O.S.).
A complete evaluation of glaucoma involves checking the eye pressure, clinical examination of the optic nerve, photograph if necessary, and baseline peripheral vision test called “visual field examination.” Later onpachymetry and or HRT is also recommended for evaluation and follow-up of glaucoma. If diagnosed early, medicine can be prescribed to treat this disease. The risk factors for glaucoma increase with increasing age, positive family history, myopia, history of diabetes etc.
You are legally blind when the best corrected central acuity is less than 20/200 in your better eye, or your side vision is narrowed to 20 degrees or less in your better eye. Even if you are legally blind, you may still have some useful vision.
Low vision is a term describing a level of vision below normal (20/70 or worse) that cannot be corrected with conventional glasses. Low vision is not the same as blindness. People with low vision can use their sight. However, low vision may interfere with the performance of daily activities, such as reading or driving.
Macular degeneration is damage to the central part of the retina called the macula. The macula is a small area of the retina that allows us to see fine details clearly. When the macula doesn’t function correctly, we experience blurriness or distortion in the center of our vision. Macular degeneration affects both distance and close vision, and can make some activities – like threading a needle or reading – difficult or impossible. Macular degeneration is the leading cause of central vision loss among older people.
Night blindness is more appropriately called as “impaired dark adaptation.” People with night blindness see poorly in the darkness but see normally when adequate amounts of light are present. The condition does not actually involve true blindness, even at night.
When the two eyes are not properly aligned and looking directly at the same thing, a prism can be ground into the lenses in order to re-align them. This can occur with strabismus or in situations where the eyes are properly aligned but are under a tremendous amount of strain in order to keep them aligned. The value under the ‘prism’ heading of your prescription denotes the strength of the prism.
Radial Keratotomy (RK) is the oldest of the modern refractive procedures. RK can correct nearsightedness by changing the shape of the cornea. Microscopic incisions of 90% depth, placed in a radial pattern, like the spokes of a wagon wheel, reshape and flatten the central cornea, allowing light to focus more precisely on the retina. The length and number of incisions determine the effect of the surgery. Patients with less than 3 diopters of nearsightedness and stable prescriptions are the best candidates. Today, RK is seldom performed because the Excimer laser can achieve the same effect without the need for placing deep corneal incisions.
One major concern about RK is the weakening effect of the radial incisions on the strength of the eye, which makes the eye more susceptible to rupture in the event of an injury. Another concern is that eyes with radial keratotomy can experience progressive flattening, making them farsighted over time. These problems are avoided today through the use of other procedures, such as LASIK.
Refraction is the process of measuring your best corrected vision through various lenses. This measurement is part science and part art and utilizes a number of objective and subjective testing methods. It is common to have slightly different measurements in your refraction depending on factors such as examiner, type of tests used, time of the day, lighting conditions, and the use of dilating drops.
This is the main part of your prescription. This number denotes the strength of the lens as measured in diopters.
Strabismus is a visual defect in which the eyes are misaligned and point in different directions. One eye may look straight ahead, while the other eye turns inward, outward, upward or downward.
The laser allows a much more precise surgery, with less swelling and bruising. During surgery proper care is taken to avoid any unnecessary exposure to the laser. There is no risk from the laser, and Dr. Tandon feels that there are important benefits in precision and faster recovery.
There is no correct age for obtaining eyelid surgery. Excessive skin in the upper lids, or bulging fat in the lower lids are commonly seen with signs of aging. The exact age depends on your heredity. Certainly, women in their forties and fifties comprise the majority of patients. If you are in good health without serious eye problems, your age alone should not keep you from having this procedure.
There is no correct age for obtaining cosmetic radio-surgery. Certainly, girls in their twenties comprise the majority of patients. If you are in good health without serious medical problems, your age alone should not keep you from having this procedure.
The “standard plastic” lenses are often called “Hard Resin”, “CR-39 plastic”, or just “plastic” lenses. CR-39® is actually a PPG Industries registered trade name for a DADC (diallyl diglycol carbonate) polymer that was introduced in 1941. The “CR” stands for Columbia Resin and CR-39 was the 39th batch or formula made by Columbia Laboratories in Ohio. The “hard resin” or “CR-39 plastic” is a thermoset plastic meaning it cannot be molded or bent when heated. On the other hand, the polycarbonate polymers are thermoplastic which means that the lenses can be formed by melting polycarbonate pellets and injecting them into a mold.
In conventional technique, a knife is used to cut the skin and remove the underlying fat. The skin is then closed with either regular or dissolvable sutures. In laser technique, CO2 laser is used to cut the skin and remove a thin strip of muscle and fat. Then stitches are placed to make the crease and close the skin. The stitches on the skin dissolve by themselves after a week or 10 days. Regular stitches may also be used.
Our highly skilled opticians help you in selecting the right frame to fit your face comfortably. People usually do not know what to look for in a frame and end up choosing frames that are not appropriate for their prescription or their facial features.
NeoVision’s opticians will also help you in selecting the right lens material (CR-39 plastic, polycarbonate, Trivex, hi index), lens design (single vision, bifocal, trifocal, progressive), and lens coatings (scratch resistance, UV protection, anti-reflective, transitions, polarized) to match your lifestyle.
The optician will measure the precise inter-pupillary distance (PD) to ensure accurate placement of lenses in the frame. PD is the distance from the center of the pupil (black circle) in one eye to the center of the pupil in the other eye. For multifocal lenses (progressive, bifocal, or trifocal), an optician must determine the correct position for the line that divides the distance vision lens from the near vision lens. The optician will mark the demo lenses for the correct position of this line. The height from the bottom of the lens up to the correct position of the lens-dividing line is called “seg-height.” In order to determine the correct seg-height, the optician must fit and adjust the eyeglass frames on the wearer’s face. The seg-height is different for every pair of glasses, and can only be determined after the eyeglasses have been fit to your face by an optician. If your eyeglasses are manufactured without the appropriate measurement of PD and seg-height, they may not function properly for you. Never order eyeglasses without trying the frame on, optician fitting the frame on your face, and taking the measurements.
An aspheric lens is flatter than a spherical lens.
The key difference in different techniques is either in the quality of vision (CustomLASIK is better) or the safety of procedure (IntraLase is safer). As far as visual acuity is concerned, generally the first day after laser vision correction, most patients experience a large improvement in their vision, to approximately 20/40 or even better. This greatly depends on your preoperative prescription. You can expect to regain approximately 75 to 80% of your vision in the first two to three days after surgery. The remainder of your vision will improve gradually over several weeks. If you have significant astigmatism, or are very near-sighted / far-sighted, vision recovery and stabilization are slower.
The macula is in the center of the retina, the light-sensitive layer of tissue at the back of the eye. As you read, light is focused onto your macula. There, millions of cells change the light into nerve signals that tell the brain what you are seeing. This is called your central vision. With it, you are able to read, drive, and perform other activities that require fine, sharp, straight-ahead vision.
A special cylindrical lens is needed in order to correct astigmatism. Not only does the strength of the cylindrical lens need to be specified, but the lens itself must be rotated into a specific position in order to provide the proper vision correction. The axis represents the amount of rotation of the cylindrical lens in degrees ranging from 1 to 180.
The base is to the prism what the axis is to the cylinder. As you know, a prism is shaped like a triangle. The thicker the triangle at its base, the stronger is the power. Much like the axis specifies the direction of rotation of the cylindrical lens for astigmatism, the prism must also be rotated into a specific position. But the rotation of the prism is simply specified as ‘base in’ or ‘base out’ (where ‘in’ means towards the nose) or ‘base up’ or ‘base down’. Only these four positions exist as opposed to the 180 positions that can be specified for a cylindrical lens. However, orientations between these four positions can be specified by using combinations of horizontal and vertical prisms in the same lens.
Diabetic retinopathy: This disease is a leading cause of blindness in American adults. It is caused by changes in the blood vessels of the retina. In some people with diabetic retinopathy, retinal blood vessels may swell and leak fluid. In other people, abnormal new blood vessels grow on the surface of the retina. These changes may result in vision loss or blindness.
Fluctuation in vision. The excess sugar in diabetics can cause this condition. A good control of blood sugar is recommended to minimize this problem.
The optic nerve is a bundle of more than 1 million nerve fibers. It connects the retina, the light-sensitive layer of tissue at the back of the eye, with the brain. A healthy optic nerve is necessary for good vision.
Eyelid surgery can correct drooping upper lids which can hang down and interfere with peripheral vision. By removing the excess wrinkled skin, blepharoplasty “opens up” the eyes and gives the face a fresher, brighter, and more youthful and rested appearance. During lower eyelid surgery, bulging fat is removed, as well as a minimal amount of skin. Thus blepharoplasty procedure improves over-hanging eyelid skin in the upper lids and removes the puffiness and swelling of the lower eyelids.
Although most skin outgrowths are harmless and can be left alone safely, they may be treated for the following purposes:
Anisometropia is a condition where there is a significant difference in the refractive errors of the two eyes. If this condition is present in infancy and is undetected or untreated, it often results in the development of lazy eye or amblyopia in the weaker eye. The greater the amount of the difference, the more likely the development of lazy eye will be. A problem can occur when glasses are made for an anisometropic individual. The difference in the powers of the lenses induces a prismatic difference that can cause double vision in off-center areas of the lens, which can be compensated for by the use of slab-off prism.

There is no correct age for obtaining pterygium surgery. If you are in good health without serious eye problems, your age alone should not keep you from having this procedure.
Cataract surgery is a highly successful procedure. Over 95% of patients experience improved vision, unless there is a problem with the cornea, retina, optic nerve or other structures.
Eyelid surgery is very successful in patients who have been properly educated and have reasonable expectations. Realistic expectation on the part of the patient is critical to success. Sagging tissue of the eyelids and bulging fat pads can certainly be removed.
Cosmetic radio-surgery is very successful in patients who have been properly educated and have reasonable expectations. Realistic expectation on the part of the patient is critical to success.
Pterygium surgery is very successful. However, the recurrence rate is often as high as 30 to 40 percent and they tend to come back bigger and faster.
In early stages, an angiogram is done to detect the sites of bleeding and proper and timely laser treatment to clog these sites can prevent further loss of your vision. In later stages, surgery is done to remove the blood.
Most sight-threatening diabetic problems can be prevented by laser treatment if it is given early enough. It is important to realize however, that laser treatment aims to save the sight you have, not to make it better. The laser, a beam of high intensity light, can be focused with extreme precision. So the blood vessels that are leaking fluid into the retina can be sealed.
Although annoying, floaters are not usually vision threatening and do not require treatment. Often floaters diminish and become less bothersome over time. If a floater appears directly in the line of vision, moving the eye around will often help. In cases where floaters do indicate a more serious condition such as retinal tear, lasers can be used to prevent vision loss.
Like floaters, unless they represent the symptoms of a more serious condition, flashes do not require treatment. Flashes which are a result of the vitreous pulling away from the retina will eventually stop. However, flashes may be a warning for retinal detachment which needs immediate medical attention.
If neither of your eyes can see better than 20/60 without improvement from glasses or contacts, you may be defined as visually impaired. In addition, poor night vision, limited side vision, double vision and loss of vision in one eye may also determine visual impairment.
We recommend polycarbonate or high-index aspheric lenses. Avoid rimless frames.
We recommend polycarbonate or high-index lenses in a small frame. Avoid rimless frames.
Direct trauma to the eye can lead to retinal breaks, holes, or tears that occur days, weeks, months, or even years after the incident.
We at NeoVision perform a very thorough individual evaluation to determine your suitability for the LVC surgery. Determining the right procedure based upon your profession and overall lifestyle is very important. There are many considerations to make before recommending a procedure that would best suit you as an individual. We will advise you on the treatment option best suited to your eyes, whether that is LASIK,CustomLASIK, IntraLase, PRK, or no surgery at all. In approximately 10-15 percent of cases, we find that people are not ideal candidates for refractive surgery, and we will counsel you accordingly. In general, a good LASIK candidate is at least 18 years old, has healthy corneas, and has maintained a stable eye prescription for the last 12 months.
Certain medical conditions may exclude a person as a candidate for the LVC procedure. These conditions include, but are certainly not limited to:
Center is the thinnest part of a minus (concave) lens.
Center is the thickest part of a plus (convex) lens.
Knowing the symptoms of a retinal detachment is your best defense. Also seek immediate eye care if you experience any symptoms as listed above have regular dilated eye exams if you are very nearsighted or if you have a family history of retinal problems be sure to have your eye doctor examine your eye after any serious eye injury always wear safety eyewear during sports and other hazardous activities
Your sight will usually improve within a few days, although complete healing may take several months. It is a good idea to have some help at home if you can, especially if you find it difficult to put your eye drops in. You can do light housework, cooking, walk, and climb stairs.
Take the following precautions:
Sunglasses are used for three main reasons: health, performance, and fashion. A quality pair of sunglasses should provide all three functions. Lenses should be of high optical clarity and protect your eyes from harmful effects of UV radiations so that you are protected from developing early cataracts or pterygium. By reducing intense bright light as well as glare, sunglasses should keep you safe whether you are driving or participating in active sports. If you have sensitive eyes, you may also want your sunglasses to filter out more light. Your glasses should also protect your eyes against powerful damaging impacts.
Your choice in sunglasses will also be influenced by fashion. Wire frames go well with most outfits but tend to be more fragile than plastic frames. Wrap-around frames with large lenses will protect you from ambient and direct light and glare from every angle. Wraparounds stick to your face and are in fashion with the surfing, skating, and snowboarding enthusiasts. How your sunglasses look, ultimately, depends on your face, square and rectilinear glasses look better on round faces, and square faces are well suited to oval frames. Strong, lightweight composite or metal frames are typically used for brand-name sunglasses. The higher-quality sunglasses generally have tension springs connecting the arms to the face. Brand-name sunglasses with polarized polycarbonate lenses are comfortable to wear and do not distort colors.
There are two primary ways to remove a cataract. Your ophthalmologist can explain the differences and help determine which is best for you:
Phacoemulsification, or phaco or small incision cataract surgery. This method used today is an advanced method of cataract removal. Your ophthalmologist makes a small self-sealing incision on the side of the cornea (the clear, dome-shaped surface that covers the front of the eye). The doctor then inserts a tiny probe into the eye. This device emits ultrasound vibrations (pulsing at 40,000 cycles per second) that soften and break up the cloudy center of the lens so it can be removed by suction. This leaves the outer membrane of the lens intact and transparent and provides support for other vital eye components. A specially formulated fluid replaces the fragments during the suction process. Combined with the foldable lens implant, and no-stitch surgery, phacoemulsification is an advanced method of cataract surgery.Phacoemulsification requires more costly supplies and support equipment than other techniques. The surgeon must also have advanced training and considerable experience. Advocates find these additional requirements to be well worth the cost and effort.The test is called stereopsis.
A week or two before surgery, your ophthalmologist will measure the curvature of the cornea and the size and shape of the eye. For patients who will receive an IOL, this information helps your doctor to choose the right type of IOL.
Allergy shots, a desensitization process, can be helpful for some people in reducing symptoms and the need for other medications. There are also various topical and oral medications readily available at local pharmacies and drugstores. For particularly serious cases, a variety of prescription medications are also available.
Most medications fall into the antihistamine category, either topical or oral. Both work to block the release of histamine, which causes many of the symptoms. Topical antihistamines, in the form of eye drops, may prove the most effective way to get relief from Seasonal Allergic Conjunctivitis. Unlike oral medications, eye drops allow the medication to get directly to the affected eyes. Many contain both an antihistamine and a decongestant. Applied when necessary, these drops can alleviate within minutes most of the annoying symptoms such as itching, redness, tearing and swelling.
New and highly potent prescription topical antihistamines are also available from your doctor that work on contact and provide hours of relief with virtually no side-effects.
Soft contact lenses, especially dailies, are most appropriate for occasional wear.
Polycarbonate lenses in a flexon frame with spring hinges.
We highly recommend polycarbonate lenses that are more impact resistant.
Plus (convex) lenses are used for correcting hyperopia (far-sightedness) and presbyopia (aging eye vision).
There are some patients who feel that their night or reduced-light vision is poor after surgery even when their uncorrected vision is good or excellent in normal lighting. This may be a significant issue for some patients while driving at night, playing tennis or baseball at night, or while participating in similar activities occurring in low lighting conditions. If activities of this sort are very important in your lifestyle, be sure to discuss it with your surgeon. Note that the CustomLASIK reduces frequency of night vision problems following treatment and results in clearer, crisper vision compared to treatments performed without CustomLASIK.
Daily-wear contact lenses are designed to be removed each day for cleaning, and should be taken out before you sleep or nap. Extended-wear lenses can be worn continuously for up to seven days before they are removed for cleaning.
You should plan to take it easy and not work out or play sports for a week. Aerobic and other exercise programs are not allowed for at least two weeks to decrease the risks of bleeding, swelling and bruising. More strenuous activities, such as weight-lifting and contact sports, are not allowed for at least two weeks. Absolutely no bending, lifting or straining during the postoperative period as these activities can increase swelling and delay healing.
You can resume regular exercise, aerobic, play sports, or work out immediately after the procedure.

You may take a tub bath and wash your hair in the sink about one week following the procedure. Hot steamy showers should be avoided because they could prolong swelling. Routine showers at one week are fine.
Generally, you should stay out of contact lenses for at least two weeks after surgery. Get final clearance from your surgeon before using contact lenses.
Generally, you should stay out of contact lenses for two weeks after surgery.
It is a good idea to buy new mascara after surgery to avoid infection and it is best to wait for 1 week before using eye makeup.
By age 45, almost everyone notices a decline in close vision. While some people may choose to go without eyeglasses if their lifestyle doesn’t require a lot of reading, that solution doesn’t work for most people. When you begin to notice problem in reading clearly, you should have your eyes examined.
Patients take their pain medication as needed. You will begin the antibiotic and pain medications when you arrive home from surgery.
Patients take their pain medication as needed. You will begin the antibiotic and swelling medications when you arrive home from surgery or next day after surgery.
People with diabetes should schedule eye exams at least once a year. More frequent medical eye exams may be necessary after the diagnosis of diabetic retinopathy. You should have your eyes checked promptly if you have visual changes that affect only one eye; last more than a few days; and not associated with a change in your blood sugar.
Some patients have thin corneas relative to the amount of treatment needed to correct their prescription. Other patients have an abnormal epithelium (the outer layer of the cornea) that would be more prone to an abrasion during LASIK. Either of these two conditions would make PRK the preferred procedure.
If your child shows ANY sign from the list below, you should consider a comprehensive eye exam by an ophthalmologist.
If your child shows ANY sign from the list below, you should consider a comprehensive eye exam by an ophthalmologist.
IntraLase was approved by FDA in 2002. Since then more than 100,000 IntraLase procedures have been done.
Typically a person’s vision will fluctuate from birth through childhood and up to approximately eighteen years of age before it stabilizes. At forty years of age, difficulty with near vision will occur and continue to progress up to approximately sixty years of age.
We see all surgery patients one day after the surgery. Further follow-up will depend upon your individual condition and schedule. Dr. Tandon will be available to see you in the office, if necessary. There is no charge for future visits after surgery.

You can quickly return to many everyday activities, but your vision may be blurry. The healing eye needs time to adjust so that it can focus properly with the other eye, especially if the other eye has a cataract. Ask your doctor when you can resume driving.
If you just received an IOL, you may notice that colors are very bright or have a blue tinge. Also, if you’ve been in bright sunlight, everything may be reddish for a few hours. If you see these color tinges, it is because your lens is clear and no longer cloudy. Within a few months after receiving an IOL, these colors should go away. And when you have healed, you will probably need new glasses.
This may be an allergic reaction to deposits on contacts or possibly an eye infection. Set up an appointment with your eye doctor.
Both are equally effective. It is your preference. Generally, people match the color of transition lenses with the color of the frame.
Contact lenses can be worn by just about everybody to correct just about any eye condition. They can correct near-sightedness and far-sightedness, as well as astigmatism and presbyopia. Contact lenses can even be worn by people who don’t need vision correction, but who simply want to change their eye color. Remember, contact lenses may not be a good choice for you if you have repeated eye infections, suffer from severe allergic reactions, have dry eyes, or are in a dusty environment.
If you are 21 years of age or older and wear glasses or contacts to correct nearsightedness, farsightedness and / or astigmatism you may benefit from CustomVue™. If you meet the criteria, you should see your eye doctor for more information.
A natural part of the aging process is the development of wrinkles, often around the eyes. Skin around the eyes also becomes less elastic, resulting in droopy eyelids. Sometimes this happens at an early age. You may start working your forehead muscles harder in an effort to lift your drooping eyelids. This may cause brow aches and fatigue. If you are having these symptoms, or simply do not like the way your eyelids appear, you may be a candidate for a blepharoplasty.
If your vision cannot be improved by changing the prescription of eyeglasses and you are limited in doing your daily routine activities such as driving, playing golf, watching television, or reading due to cataract formation, you are a candidate for cataract surgery.
All people, including children, are at risk. People who spend long hours in the sun because of work or recreation, those who have had cataract surgery, individuals who have certain retinal disorders, and those who take certain medications, such as tetracycline, sulfa drugs, birth control pills, diuretics, tranquilizers etc. are at even higher risk.
Anyone with diabetes. The longer someone has diabetes, the more likely he or she is to get diabetic retinopathy. Nearly half of all people with diabetes will develop some degree of diabetic retinopathy during their lifetime.

Color deficiency is a sex linked character. Females are either not affected or they are the carriers with a normal vision. The males within the same family are affected. There is only a 50/50 chance that sons of carrier mothers will have altered color vision.
A female can inherit defective color vision gene either from her color deficient father or her carrier mother. Since the pattern of inheritance is known, future generations of color blind individuals can be easily predicted.
Polycarbonate lens material is so tough that you can hit it with a hammer and it won’t shatter. Ordinary polarizing lenses are made out of plastic (CR-39) and are not shatter resistant. In addition, polycarbonate lenses absorb harmful UV radiations.
Most sight loss from diabetic retinopathy can be prevented but it is vital that it is diagnosed early. You may not realize that there is anything wrong with your eyesight, so regular eye checks are extremely important.
Even lenses without correction are medical devices that can cause problems to your eyes. If you have never worn contact lenses, you need to be fitted by an eye doctor and taught how to insert, remove, and disinfect them. If you already wear clear lenses that are available in a tint then you may substitute with a tint without a problem.
Your doctor has a right and a responsibility to put an expiration date on your contact lens prescription, to ensure that you receive regular check-ups to rule out the possibility of long-term complications of contact lens wear that you may be unaware of.
If a child has strabismus and he/she is focusing with one eye, the other eye becomes lazy.
Children are at a higher risk from the harmful effects of UV since they generally spend more time outside in the sun. Select sunglasses that suit your child’s active lifestyle. The lenses should be impact resistant i.e. made of polycarbonate.
People look older and more tired once aging skin creates baggy or puffy eyelids, and since this occurs much earlier than wrinkles in the face, it is common for people to elect eyelid surgery years before they need a facelift.
Although most pterygia are harmless and can be left alone safely; they are surgically removed for the following reasons:
Because the healing occurs in the interior of the cornea, and no re-growth of surface cells are required. The corneal flap protects the treated area and there is usually little or no post-op discomfort. Visual rehabilitation is much quicker.
Until now, physicians were forced to practice one-size-fits-all vision. An off-the-shelf lens corrects an individual’s vision fairly well, but it does not correct it precisely because it is not uniquely tailored to that person’s fingerprint of vision. For the first time, WaveScan technology captures unique imperfections in each individual’s vision that could not have been measured before using standard methods for glasses and contact lenses.
Yes. Your surgeon will need you to fixate on a red blinking light in the microscope during the procedure. This will ensure that the tissue removed will be centered over your pupil.
No. LVC surgery is an out-patient surgery. There is no need for hospitalization.
There is no discomfort at all during the LASIK or PRK procedure. You will be awake and comfortable throughout the procedure. Following the PRK procedure, expect a gritty sensation with some mild to moderate discomfort in the first few days, which will improve with time.
LASIK procedure is also painless; however, there is about 30 seconds of firm pressure while the corneal flap is being created. Following the procedure, patients are slightly more comfortable than patients undergoing PRK, experiencing only a 4-6 hours of scratchiness in the eye. Sleep during these first hours immensely reduces any discomfort you may feel.
After any surgical procedure, some discomfort can be expected. All patients are provided with prescriptions for pain medication. Patients have surprisingly little discomfort after most eyelid procedures. Generally over the counter Tylenol is all patients need (together with ice packs) placed over their eyes for 24 hours. An occasional patient will report unmanageable pain after surgery.

Cosmetic radio-surgery by Surgitron is painless. To further ensure your total comfort, a small local anesthetic injection is given to the area of treatment. After any surgical procedure, some discomfort can be expected. All patients are provided with prescriptions for pain medication. Patients have surprisingly little discomfort after most radio-surgery procedures. Generally, over the counter Tylenol is all patients need for 24 hours. An occasional patient may report unmanageable pain after surgery.
Most first time wearers are delighted with the level of comfort that contact lenses provide. Initial contact lens fittings by an eye doctor can minimize any irritation associated with new lenses. After a brief adjustment period, most people report they can no longer feel contact lenses on their eyes.
Yes. Postoperative prescriptions are provided well in advance of surgery day so you arrive home completely prepared. Postoperative prescriptions and over-the-counter medications for cataract patients include the following: an antibiotic drop and an anti-inflammatory drop four times a day. These drops will be tapered off over 3 weeks.
Usually no prescription medicines are needed before or after radio-surgery. Over-the-counter pain medications and topical antibiotic ointment is needed after surgery.
Yes. Postoperative prescriptions are provided well in advance of surgery day so you arrive home completely prepared. Postoperative prescriptions and over-the-counter medications for pterygium patients include the following: Pain medication (usually Vicodin hydrocodone) to minimize any discomfort following surgery and antibiotic ophthalmic ointment (Polysporin bacitracin ophthalmic) to place gently in the operated eye.
Yes. Postoperative prescriptions are provided well in advance of surgery day so you arrive home completely prepared. Postoperative prescriptions and over-the-counter medications for blepharoplasty patients include the following: an antibiotic ointment (Polysporin / bacitracin ophthalmic) to place on the sutures and gently in the corners of the eyes and pain medication as needed. You should start ointment the day of surgery. You will be asked to use ice pack for 24 hours after surgery.
Cataract surgery and lens implantation are intended to restore your vision to normal, minimizing your dependence on glasses / contacts. Although many patients are able to function without glasses, most patients will find that they need glasses for near vision (reading and close-up work), distant vision, or both after cataract surgery.
Most normally sighted patients require readers in their mid-forties. This is caused by the normal weakening of the focusing muscles of the eye known as presbyopia, which usually starts around the age of 40 – 45. This condition occurs with or without LASIK.
Those patients who currently have bifocals will still need reading glasses after the surgery unless they opt for a treatment plan called monovision, wherein one eye is corrected for distance and the other for near vision. At some point in your 40’s you will probably need reading glasses for close viewing, whether or not you had refractive surgery.
Patients may still need or want to wear glasses following refractive surgery for certain tasks even though almost everyone will see vastly better without glasses than they did before surgery. Some patients, especially those over 40, will need glasses for close work such as reading, sewing, computer use, etc., even though they might have good visual acuity for farther away objects.
Although the change may be significant to you, it’s not uncommon that friends and family members don’t really notice the change.
Most patients’ two eyelids are a bit different. The goal of the surgery is to make them look exactly the same. It is generally the result but cannot be guaranteed.
Most of these operations are covered by insurance. If cataract is interfering in your field of vision, the procedure may be covered as a “medically necessary” surgery and some insurance plans will pay for all or part of the surgery. You should check with your insurance carrier about the coverage.
No, these procedures are cosmetic in nature and are not covered by insurance.
Most of these operations are cosmetic in nature and are not covered by insurance. In some older patients, if your vision is impaired by the excessive skin of the upper eyelids, some insurance plans will pay for all or part of the surgery. We will perform a test for visual field restriction, and if there is impairment in this area, we will dictate a letter of necessity for your insurance company. Final decision is made by your insurance carrier after reviewing your condition and the photographs. Lower eyelids are not covered by insurance unless there is a deformity. Patients should check with their insurance carrier about their coverage.
Most of these operations are cosmetic in nature and are not covered by insurance. If pterygium is interfering in your field of vision, the procedure may be covered as a “medically necessary” surgery and some insurance plans will pay for all or part of the surgery. Pinguecula are generally not covered by insurance unless there is a medical reason. Patients should check with their insurance carrier about their coverage.
LVC is an elective procedure. As a result, generally insurance companies do not pay for vision correction procedures. You can check with your plan administrator to find out what is your coverage.
Glaucoma surgery is different from the cataract surgery. In cataract surgery, when the cloudy lens is replaced by lens implant, the vision usually improves. In glaucoma, the vision is lost due to nerve damage. This damage is permanent. Glaucoma surgery is aimed to prevent further loss of vision. It cannot restore the lost vision. Therefore, early diagnosis is very important to prevent this permanent loss.
Most likely not. However, it is conceivable that your vision could have a delay in recovery such that there could be a problem doing your work or a hobby or interfere with taking a trip or vacation. You will be asked to restrict certain activities for about 1-2 weeks. You should try to always have more than enough time between your surgery and something you really need or want to do, especially if the activity requires good vision.
No, there is no scientific evidence that TV sets emit rays that are harmful to the eyes.
No. Glasses and contact lenses allow you to see comfortably. When you remove them, you see less comfortably. This contrast is what makes some people believe their vision is worse for wearing glasses. Corrective lenses won’t make your vision problems go away, nor will they worsen them. They only correct the symptoms.
