PRK

PRK or Photo-Refractive Keratectomy treats refractive errors by removing tissue from the surface of the cornea. First, the epithelium, a thin layer of protective skin on the front of the cornea will be removed. Next the Excimer Laser, usually in less than a minute, will remove the proper amount of tissue thus reshaping the surface of the cornea. A bandage contact lens is then placed on the eye for 2 to 3 days until the epithelium heals.

Patients often experience discomfort and a watery eye for the first 24-72 hours after their procedure. Vision may take up to three months to stabilize.

Possible risks and complications include infection (very rare and usually treated with eye drops), over or under correction, glare, or post-operative haze.
