LASIK (laser in situ keratomileusis)


LASIK (laser in situ keratomileusis) is a refractive surgery technique that is intended to correct myopia, hyperopia and/or astigmatism, thereby reducing or eliminating the need for contact lens or glasses for vision correction. The procedure involves the creation of a flap in a portion of the cornea that is peeled back to expose the inner portions of corneal tissue. Next, a process called photoablation, for which an excimer laser is used, removes microscopic amounts of the internal corneal tissue that changes the curvature of the cornea. Upon completion of this process, the flap is returned to its original position.




The American Academy of Ophthalmology issued a Preferred Practice PatternĀ® position statement in 2013 that found LASIK safe and effective for certain individuals with myopia, hyperopia and/or astigmatism, but cautions that not all individuals are good candidates for this procedure.
