Description:

Topical anesthesia (numbing eye drops) is used. The exact surgical method depends on the patient. In many cases, the ophthalmic surgeonwill use an instrument called a keratome to lift apiece of tissue from the surface of the cornea.A laser re-shapes the surface of the cornea and thetissue isput backinto place.

The procedure is usually painless and the improvement in vision is usually immediate. The patient can quickly return to most activities, but must avoid bumping the eye or submerging in water (swimming, for example).

This method of refractive surgery offers fewer side effects compared to radial keratotomy, which was common in the 1980's. Usually both eyes are done in the same session.

Indications:

Refractive surgery is used to treat nearsightedness so that corrective lenses will no longer be necessary. Most forms of nearsightedness can be reliably corrected.
