How LASIK Works
|
|
|
LASIK is a refractive surgical procedure to help correct vision
problems. The term LASIK is an abbreviation or acronym for
laser-assisted in-situ keratomileusis, which means "to reshape the
cornea, from within, using a laser." In LASIK, the corneal surface
is treated underneath a protective corneal flap. It is one of
several corrective procedures for the treatment of familiar vision
problems that you may already have heard of, including
nearsightedness, farsightedness and/or astigmatism. While glasses and contact lenses also help correct problems such as these, they are considered vision aids, not surgical procedures. LASIK and other procedures are, in fact, designed to help people eliminate, or reduce the need for glasses or contact lenses. LASIK is not the appropriate procedure for everyone and it is important to know if it is right for you. Consultation with your physician can help determine this. You may experience nearsightedness, farsightedness and/or astigmatism because your cornea is inadequately shaped for the dimensions of your eye. In use since the late 1980s, LASIK utilizes a laser beam to remove small amounts of tissue from the cornea to reshape it and correct the refractive error. The reshaped cornea then focuses images directly on the retina. For many patients, a successful LASIK procedure can mean clearer vision with the potential to eliminate glasses or contact lenses. The following
animation will show you how LASIK works to correct different vision
problems. |
