How are LASIK and PRK performed?
LASIK is done by first creating a flap of the corneal surface of the eye using either a microkeratome or a laser (Intralase). Next the flap is lifted and the excimer laser is used to sculpt the eye to correct your prescription. The flap is then replaced. With PRK no flap is created. PRK is done by removing the top skin layer of the eye or epithelium and then the excimer laser is used to sculpt the eye to correct your prescription. A contact lens is then place on the eye as a band-aid and is later removed.
