Photorefractive keratectomy, or PRK, uses the same excimer laser used in LASIK surgery and is performed to reshape the cornea in an attempt to correct mild to moderate myopia (nearsightedness). According to the US Food and Drug Administration (FDA), PRK has a 95 percent success rate. Only about 15 percent of patients need glasses, occasionally, following surgery.
