PRK (photorefractive keratectomy), LASEK (laser epithelial keratomileusis), and epi-LASIK (epithelial laser in-situ keratomileusis) use a laser to reshape the cornea. By reshaping the cornea, these surgeries allow light to focus on the retina and thereby correct a person's vision. With PRK, the top layer on the...
LASIK (laser in-situ keratomileusis) is a surgery that flattens the cornea. It is the most common laser surgery for correcting nearsightedness (myopia) and astigmatism. LASIK makes a small flap in the cornea and removes some of the tissue exposed by the flap. The laser removes tissue from the cornea very accurately...
