Photorefractive Keratectomy, also called PRK laser eye surgery, is a procedure designed to correct nearsightedness, farsightedness and astigmatism. This procedure involves sculpting the surface of the eye in an effort to improve visual acuity. This process differs from LASIK in which a flap is cut and the cornea is reshaped. Nearsighted patients have the cornea flattened while farsighted patients have the cornea steepened.
