Frequently Asked Questions

Are both the eyes affected by a glaucoma attack?

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.

Are red spots or stains on the white of my eye serious?

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.

Are the risks of complications in cataract surgery greater with an IOL?

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.

Are there any dietary restrictions before the procedure?

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.

Are there any lasers used to remove the cataract?

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.

Are there any risks of wearing contact lenses?

SP_150Any 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.

Are there any visible scars from the pterygium surgery?

Most of the time there is no visible scar after the healing is complete. Once healed, the hairline scars will fade.

Are there different types of glaucoma?

Glaucoma TreatmentYes. In summary there are four main types of glaucoma:

  • Open Angle Glaucoma (OAG): In OAG, there is excess secretion of the fluid inside the eye but there is no defect in the drainage system.
  • Narrow Angle Glaucoma (NAG): In NAG, the fluid secretion inside the eye is normal, but the drainage system is narrow.
  • Low Tension Glaucoma (LTG): In LTG, the drainage system is normal, fluid secretion is also normal (as tested by normal eye pressure), but even then there is damage to the optic nerve.
  • Other than these, there are many conditions, which can lead to secondary glaucoma.
At what age should children have their first eye exam?

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.

Can I continue to wear my disposable contact lenses if they are still comfortable after the recommended wearing period?

Eyelid Surgery Union CityNo, 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.

Can I go swimming while wearing contact lenses?

Eye Doctor San JoseGenerally 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.

Can I play sports or work out while wearing contact lenses?

Eye Doctor Union CityYes, 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.

Can I share contacts with someone else?

Cataract Surgery Union CityNo! 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.

Can I sleep in my contact lenses?

Can I sleep on either side after surgery?

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.

Can I store my contacts dry?

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.

Can I store my contacts in homemade saline?

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.

Can I store my contacts in tap water?

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.

Can I travel by airplane while wearing contact lenses?

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.

Can I use my eyeglass prescription for ordering contacts?

Cataract Surgery WavefrontNo, 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.

Can I use paper tissues for cleaning my glasses?

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.

Can I wear contact lenses if I have had refractive 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.

Can I wear makeup with my contact lenses?

Yes. Try to avoid getting makeup on your lenses. Always insert your lenses before applying eye shadow, eyeliner, and mascara.

Can a child have a lens implant?

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.

Can all candidates have a pterygium surgery?

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.

Can cataract surgery be a medical necessity?

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.

Can contact lenses damage cornea?

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.

Can contact lenses fall out of eyes?

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.

Can contact lenses slip to the back of eye or be “lost” behind the eye?

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.

Can diabetes cause bleeding inside the eye?

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.

Can diabetes cause cataract?

Yes. Uncontrolled blood sugar can result in cataract formation.

Can diabetes cause glaucoma?

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.

Can diabetes cause retinal detachment?

Yes. Bleeding and then scarring inside the eye results in retinal detachment due to traction.

Can diabetes result in blindness?

Yes. End result of uncontrolled diabetic retinopathy is permanent blindness.

Can glaucoma be 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.

Can my child wear contact lenses during sports activities?

Yes, contact lenses provide excellent vision for most sports. However, they should also use polycarbonate sports safety goggles or glasses when participating in sports.

Can pterygium surgery be a medical necessity?

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.

Can retinal detachment be treated?

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.

Can retinal detachment cause total blindness?

Yes, even a slight blockage of the vision caused by partial retinal detachment can result in blindness if not treated right away.

Do I need to see an eye doctor, if I want to wear contacts?

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.

Do I still need regular eye exams once I get contact lenses?

Cataract Surgery Union CityYes. 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.

Do gas permeable contact lenses absorb water?

No. They do not need to because the material itself allows oxygen to diffuse through it making water irrelevant.

Do retinal detachments ever disappear without surgery?

Only if the detachment is due to a successfully treated medical condition such as toxemia of pregnancy or rare forms of eye inflammation.

Do sunglasses provide protection against certain eye diseases?

SP_141There 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.

Does cataract in an infant have the same prognosis as in adults?

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 ordering my new glasses, do I need to be physically present or I can simply fax in my prescription?

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.

How are the light rays refracted by different types of lenses?

Light rays are diverged by minus (concave) lenses and converged by plus (convex) lenses.

How can I check the optical quality of my sunglasses?

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.

How can I find out if I have swapped the contact lenses in my eyes?

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.

How can I find out if my sunglasses are polarized?

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.

How can I tell if my contact lens is inside out?

The damage to retinal vessels is referred to as diabetic retinopathy.

How common are the other diabetic eye diseases?

SP_143If 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.

How common is retinal detachment?

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.

  • OD (Oculus Dextrus) is right eye
  • OS (Oculus Sinister) is left eye
  • Sphere power is the actual power of the contact lens
  • Cylinder (if any) is the power of the astigmatism correction
  • Axis (if any) is the alignment of the contact lens in the eye
  • Base curve is the shape of the contact lens
  • Diameter is the distance from edge to edge (in mm) of the lens

In most cases, the most important parts of the prescription are the Base Curve, Diameter and Sphere power.

How do I tell if I have lost the lens from my eye?

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.

How does cataract surgery improve quality of life?

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.

How does glaucoma damage the optic nerve?

Glaucoma SurgeryIn 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.

How is amblyopia treated?

Lasik Union CityInitially, 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.

How is glaucoma detected?

Cataract Surgery Union CityMost 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.

How is glaucoma different from cataract?

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.

I am young and healthy, why should I have dilated eye examination?

Retinal DetachmentDilated 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.

I wear bifocal glasses, what are my options in contacts?

You have three options: (1) wear bifocal contacts in both eyes; (2) wear one contact for distance vision, and one for near vision, this option is called monovision; or (3) wear your distance correction in the contacts, and wear reading glasses when needed.

If I am eligible for cataract surgery, what is the next step?

Schedule a pre-op appointment with your surgeon at NeoVision Eye Center. In keeping with our efforts to maintain the highest standards of patient safety and in an ongoing effort to avoid possible complications, we ask that each of our cataract patients undergo an extensive and comprehensive eye exam by an ophthalmologist prior to surgery. During your pre-op visit, your health history will be reviewed, all your questions will be answered, you will be instructed on how to prepare for surgery, you will be given the prescriptions for use after surgery and we will tell you what to expect. If you are on blood thinners, you will be asked to stop them approximately one week prior to surgery. You will be asked to sign an informed consent.

If I am eligible for the surgery, what is the next step?

Schedule a pre-op appointment with your surgeon at NeoVision Eye Center. In keeping with our efforts to maintain the highest standards of patient safety and in an ongoing effort to avoid possible complications, we ask that each of our pterygium patients undergo an extensive and comprehensive eye exam by an ophthalmologist prior to surgery. During your pre-op visit, your health history will be reviewed, all your questions will be answered, you will be instructed on how to prepare for surgery, you will be given the prescriptions for use after surgery and we will tell you what to expect. If you are on blood thinners, you will be asked to stop them approximately two weeks prior to surgery. You will be asked to sign an informed consent. Full fee for the pterygium surgery is due at the time of your pre-op visit.

If I only wear my 2-week disposable contacts part time, do I still have to replace them every 2 weeks?

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.

If one eye develops retinal detachment will the other develop it as well?

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.

If there is a history of glaucoma in my family, am I likely to inherit it?

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.

Is a retinal detachment after eye surgery related to surgeon’s mistake?

No. Retinal holes, breaks, or tears can occur after uncomplicated eye surgery performed at the highest level of excellence.

Is it important for me to keep a spare pair of eye glasses?

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.

Is it normal for the eye to feel scratchy and watery?

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.

Is pterygium surgery performed on both men and women?

Yes. It should be noted that a significant number of men and women of all ages elect to have pterygium surgery.

Is the result of cataract surgery permanent? Can cataracts grow back after 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”.

Is the result of pterygium surgery 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.

Is the treatment same for all types of glaucoma?

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.

Is there a medication or eye drop for the treatment of retinal detachment?

No. There is no medicine, eye drop, vitamin, herb, or diet that is beneficial to patients with retinal detachment.

Is there any relationship in the height of a person and the segment height?

No, there is none. A tall person may need shorter seg height and a shorter person may need a higher seg height.

Is there more than one way of writing the eyeglass prescription for astigmatism?

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.

Is there swelling and bruising after the procedure?

Your eye will look very red for about 1-2 weeks after the surgery.

Is this laser different from the laser used in Laser Vision Correction?

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.

Light rays pass through what part of a lens without being refracted?

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.

Must I wear sunglasses provided all the time?

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.

My 10 year old child wants to wear contacts, what should I do?

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.

My child has juvenile form of arthritis. Is he / she at risk for developing cataract?

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.

My contact lens is dislodged from its position, what should I do?

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.

My contacts hurt when I insert them, what could be the problem?

There are three possibilities (1) tear in contact; (2) increased deposits, or (3) contact is inside out.

My contacts lift up on my eye, what could be the problem?

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.

My eyes are bothering me, can I wear contact lenses?

It is not advisable to wear contact lenses if your eyes are bothering you, particularly if the discomfort is related to contact lens wear.

My glass frame slides down my nose all the time. What should I do?

You need frame adjustment. Also, consider lighter lenses such as hi-index or polycarbonate in a smaller frame.

Once I place my order, how long will it take for my eyeglasses to be ready?

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.

NV-19At 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.

Should I feel any pain after surgery?

For the first few hours there may be some discomfort, but usually not severe. If the pain persists, call your doctor.

What are NeoVision’s charges for a cataract surgery?

At NeoVision Eye Center, we believe the fairest approach is to offer cataract surgery for one Flat Fee. That is why we offer one global comprehensive fee, which includes all pre-operative, surgical, and post-operative care. A price estimate will be given at your consultation for cataract surgery. Fees reflect the specific problem that you have and the extent of surgery to correct it

What are my options for the reading glasses at NeoVision?

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.

What are the different types of macular degeneration?

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.

What are the instructions for taking care of my intra-ocular lens (IOL)?

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.

What are the possible complications of cataract surgery?

With prompt medical attention, most of the complications usually can be treated successfully. Possible complications that could occur during surgery include the following:

What are the risk factors for a retinal detachment?

Risk factors for retinal detachment include the following:

  • hereditary abnormalities of the retina often associated with myopia (near-sightedness)
  • aging
  • eye trauma
  • eye surgery
  • glaucoma
  • various retinal and macular diseases
  • a family history of retinal problems
  • diabetes
What are the symptoms of glaucoma?

Cataract Surgery San JoseAt 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.

What are the symptoms of retinal tear or detachment?

Retinal DetachmentA 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.

What can I do to help treat my child’s amblyopia?

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.

What can I do to protect my vision?

Eye Doctor Northern CaliforniaIf 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.

What can I do to protect my vision?

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.

What can be done to prevent diabetes related blindness?

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.

What can you do if you have already lost vision to AMD?

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.

What causes retinal detachment?

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.

What causes the 5% failures in cataract surgeries?

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.

What do the numbers on my eyeglass prescription mean?

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.

What do the numbers on the frames mean?

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.

What do you call the procedure used for creating a prescription in a lens?

The procedure is called surfacing which involves grinding the back side of a lens.

What does “informed consent” mean?

Informed consent means you have an excellent understanding about the benefits of surgery as well as any risks, and all the preoperative and postoperative information. You are making an “informed” decision as to whether surgery is right for you.

What does “informed consent” mean?

Informed consent means you have an excellent understanding about the benefits of surgery as well as any risks, and all the preoperative and postoperative information. You are making an “informed” decision as to whether surgery is right for you.

What else other than retinal breaks, tears, or holes can cause retinal detachment?

Retinal detachment can also occur as a complication of diabetic retinopathy, retinopathy of prematurity, inflammatory disorders, or trauma.

What happens after surgery?

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.

What happens during surgery?

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.

What has more focusing power, cornea or optical lens?

Cornea has 70-80% of eye’s focusing power.

What if I fall asleep with my daily contact lenses in?

Cataract Surgery FremontIf 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.

What if I have a history of bad scars?

If you have pierced ears, the way you healed there is a good indication of how you will heal from pterygium surgery. Scars on the rest of the body typically are not an indication for how patients heal following pterygium 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 pterygium surgery. If you have a history of abnormal scarring, there are medications that can be used to help prevent excess scarring.

What injuries typically cause retinal detachments?

Bottle rockets, BB guns, racquetball, tennis, golf, soccer, boxing, and diving injuries can lead to retinal detachment.

What is UV400 and what does it mean?

MS-37UV400 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.

What is a diopter?

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.

What is a lens called that has no corrective power?

A lens with no corrective power is called plano.

What is a retinal detachment (torn retina)?

Retinal DetachmentRetinal 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.

What is amblyopia?

Amblyopia SurgeryAmblyopia 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.

What is an intraocular lens or a lens implant?

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.

What is an “after-cataract”?

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.

What is cylindrical power?

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.

What is inter-pupillary distance (PD) and why is it so important for fabricating glasses?

TT-25Inter-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.).

What is involved in the complete evaluation of glaucoma?

Cataract Surgery CaliforniaA 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.

What is macular degeneration?

Cataract Surgery San FranciscoMacular 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.

What is prismatic power?

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.

What is sphere power?

This is the main part of your prescription. This number denotes the strength of the lens as measured in diopters.

What is strabismus?

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.

What is the difference between plastic (CR-39) and polycarbonate?

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.

What is the difference in NeoVision and other optical stores?

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.

What is the difference in a spherical and an aspheric lens?

An aspheric lens is flatter than a spherical lens.

What is the macula?

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.

What is the meaning of “axis” in eye glass prescriptions?

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.

What is the meaning of “base” in eye glass prescriptions?

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.

What is the most common diabetic eye disease?

SP_143Diabetic 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.

What is the most common eye complaint in diabetic patients?

Fluctuation in vision. The excess sugar in diabetics can cause this condition. A good control of blood sugar is recommended to minimize this problem.

What is the optic nerve?

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.

What is the relation in anisometropia and double vision?

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.

What is the relationship in anisometropia and amblyopia?

Anisometropia is a condition where there is a significant difference in the refractive errors of the two eyes.

What should I look for in a good pair of sunglasses?

SP-141Sunglasses 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.

What surgical methods are available to remove a cataract?

There are two primary ways to remove a cataract. Your ophthalmologist can explain the differences and help determine which is best for you:

  • Eyelid Surgery Union CityPhacoemulsification, 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.
  • Extracapsular surgery. Your surgeon makes a slightly longer incision on the side of the cornea and removes the hard center of the lens. The remainder of the lens is then removed by suction. After surgery, the wound requires six or seven stitches to close it. This type of surgery takes more time to heal and stabilize your vision.
What tests are performed before surgery?

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.

What type of contact lens is best if I want to wear only once or twice a week?

Soft contact lenses, especially dailies, are most appropriate for occasional wear.
