What happens during a photorefractive keratectomy?
The doctor will numb your eye with a topical anesthetic. The surgery usually takes about 10 minutes -- at most -- and that’s for both eyes. Your doctor will carefully remove an area of surface epithelium, or “skin,” to get to the top layer of your eye. Then he or she will use a laser to reshape it. This laser, which delivers ultraviolet light, is used on the cornea’s surface.
