An alternative procedure to LASIK, Photo-Refractive Keratectomy (PRK) does not involve the creation of a flap. Instead, the surface epithleial cells are removed using an alcohol solution. Then, the excimer laser is used to reshape the cornea. When the procedure is completed, the doctor will cover the cornea with a clear contact lens. This lens will stay in place for about a week while the cornea’s epithelial layer grows back.
PRK patients often experience a slower recovery than those undergoing LASIK but enjoy the same exceptional visual results when healing is complete. PRK may be more appropriate in patients with hyperopia (farsightedness), dry eye, thin corneas, or those with an irregular corneal surface.
