A tonopen is a portable, hand-held instrument that provides a safe, fast and accurate method of testing intraocular pressure. Eye drops that contain a drug to numb the eye are given, then the instrument is gently placed on the cornea, and a reading is obtained. A tonopen is used in emergency to quickly detect increased pressure in the eye.
