Getting acquainted with Lasik Eye Surgery

Posted in LASIK Surgery on September 20, 2008

LASIK surgery is prescribed for those suffering from nearsightedness (myopia), farsightedness (hyperopia) or astigmatism. When the light rays are focussed in front of the retina instead of on the retina, there is blurred vision. This is caused when the eye ball is slightly longer instead of spherical and the cornea curves sharply. This condition is called nearsightedness. The opposite of this condition is farsightedness.

A shorter than average eye ball with a cornea that is too flat, causes a condition where the light rays focus behind the retina. This situation is called farsightedness or hyperopia. When the cornea curves or flattens unevenly, it causes a condition called astigmatism. This condition causes blurred vision for both near and far objects. All these defects have to be evaluated and studied by experts before recommending LASIK surgery.

LASIK eye surgery (laser assisted in situ keratomileusis) has made tremendous progress in recent years. It has come as a great blessing for many people who constantly needed to wear glasses or contact lenses. With such a high success rate of these procedures, their popularity has increased considerably. This surgery changes the shape of your cornea, a transparent membrane that arcs over the pupil and the coloured part of the eye (iris). After undergoing the procedure the cornea should bend the light rays to focus on the retina instead of beyond the retina or before the retina.
