LASIK is a simple laser surgery that can be done to help a person see better without glasses. This is accomplished through a number of little cuts that change the shape of the cornea - the cover of the eye. When this surgery is done correctly, it can eliminate or reduce a person's need for prescription lenses. I have worn glasses since I was a teenager. Since my vision is fairly stable, I would be a good candidate for LASIK. Therefore, I have considered the idea of LASIK as an alternative to glasses and done a little research on the subject. Here is what I have found out.

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.
