Sometimes, dependence on eyeglasses or contact lenses can become so strenuous that individuals turn to alternative methods of repairing and correcting their vision. Lasik eye surgery is becoming increasingly popular because of its high success percentages. LASIK is an acronym for Laser-Assisted In Situ Keratomileusis, and is a surgery by which the shape of the cornea - the clear covering of the eye - is permanently altered to improve the quality of vision.

LASIK (laser-assisted in situ keratomileusis) is a version of laser eye surgery which is more complicated than PRK but allows for faster healing. It is used primarily to correct myopia, hyperopia and astigmatism by changing the shape of the cornea.

The procedure begins when the surgeon cuts a flap in the cornea using a laser or a sharp blade, leaving a small piece as a hinge. The surgeon then lifts the flap and uses a computer-guided laser to remove precise amounts of tissue from inside the cornea. Once finished, the flap is replaced.
