In an eye that has perfect vision, light rays passing through the pupil are focused by the lens to fall precisely at the center of the retina. There are many common problems that can affect the eye and prevent light rays from focusing properly on the retina.

Three of these problems, myopia - or nearsightedness; hyperopia - or farsightedness; and astigmatism can often be corrected or reduced with the use of LASIK laser surgery.

Myopia, or nearsightedness, occurs when the shape of the eye is too long or the curve of the cornea is too extreme. In this case, light rays are focused on a point in front of the retina - instead of on the retina itself.

LASIK laser surgery is a relatively simple and nonintrusive procedure that is designed to reduce or eliminate the need for glasses or contact lenses. LASIK laser surgery generally does not have any effect on a patient's overall health and there are no risks in choosing not to have the surgery.

So make sure that you ask your doctor to carefully explain the reasons behind this recommendation.
