Laser Vision Correction
-
Guides through decision to have laser surgery to correct nearsightedness. Covers benefits and risks. Discusses who is a good candidate for surgery. Includes interactive tool to help you make your decision.

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...

Photorefractive keratectomy (PRK) and laser epithelial keratomileusis (LASEK) for farsightedness use a laser to reshape the cornea so that light is refocused on the retina. The laser reshapes the cornea accurately without damaging nearby tissues. No surgical cut is needed. Either procedure may be used to correct...

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...

Laser in-situ keratomileusis (LASIK) is the preferred procedure for correcting farsightedness (hyperopia). It changes the shape of the eye. In LASIK, a thin flap is made on the cornea using a blade or laser. The flap is lifted, and a laser is applied to the central corneal tissue. The laser makes contact with the cornea...
