Photorefractive Keratectomy (PRK)
Photorefractive Keratectomy (PRK)

Photorefractive Keratectomy (PRK) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. The thin outer layer of your cornea called epithelium is removed before reshaping the underlying corneal tissue with an excimer laser. The epithelium heals itself and grows back over the corneal surface within a few days after the surgery.
