Certain vision problems, such as nearsightedness, farsightedness and astigmatism can be reduced or eliminated surgically. Vision correction surgery involves techniques that correct vision by reshaping the surface of the cornea. To correct nearsightedness, the curvature of the cornea is flattened. To correct farsightedness, the curvature is increased. To correct for astigmatism, the cornea is reshaped, producing a more evenly curved surface.
RK (radial keratotomy), AK (astigmatic keratotomy), PRK (photo-refractive keratectomy) and LASIK (laser assisted in situ keratomileusis) are the most common vision correction surgeries. The newest in LASIK is performed with Intralase technology and can be used to treat low to high levels of nearsightedness (myopia) and astigmatism, and low to moderate levels of farsightedness (hyperopia). Intralase LASIK is a procedure using the Eximer laser that has been performed for more than 30 years. LASIK treats the inner tissue of the cornea. A small cap is partially lifted from the top surface of the cornea and hinged on one side, leaving the inner portion of the cornea exposed.
For nearsightedness and astigmatism, the central part of the exposed cornea is reshaped with the laser. For farsightedness, the outer portion of the exposed cornea is reshaped. Once the reshaping is complete, the cap is put back in its original position without stitches. The reshaping process takes approximately 40 seconds and this reshaping enables light rays entering the eye to focus properly on the retina, resulting in clearer vision.
LASIK is done on an outpatient basis using an anesthetic (in eye-drop form) to numb the eye for painless surgery. The procedure usually takes less than 30 minutes. After the surgery, patients are given extensive care and medication instructions and usually return to their normal lifestyle with few restrictions during the short healing period.

Myth: Wearing glasses too much will make the eyes “dependent” on them.
Fact: Refractive errors (near-sightedness, far-sightedness, or astigmatism) change as kids get older. Many variables come into play, but most of this change is likely due to genetics and continues despite wearing glasses earlier or later or more or less. Wearing glasses does not make the eyes get worse.
