Determine If You're A Candidate For Lasik Eye Surgery
By Monica Keller
LASIK surgery works by changing the shape of your cornea, that translucent covering over your pupil and iris (the colored ring in your eye). A successful procedure will result in a cornea that bends light rays, in a process called "refraction." This focuses them more accurately on your retina, the "back wall" or "screen" on which images are projected. corrects the shape of the cornea so it is properly focused at that point, instead of another point either in front of - or behind - your retina.

The development and continuing refinement of eye surgery has been bringing better, clearer vision to millions of people who once had to rely on glasses or contact lenses. With decades of experience and ongoing advances in the underlying technology, the safety and efficacy of the procedure is now well established. Of course, complications associated with laser eye surgery still exist so it is critically important for you to find out what the procedure involves, what can possibly go wrong and whether or not you are a good candidate for it.

LASIK may be a viable option for you if you are nearsighted, farsighted or have some forms of astigmatism, all of which are called "refractive errors." Nearsightedness means that the eyeball is somewhat longer than normal, or the cornea curves too much, which results in blurred distant vision as the light focuses in front of the retina. Farsightedness occurs when a "short" eyeball, or a cornea that is "too flat" focuses light behind the retina, blurring near vision (and sometimes distant vision too). Finally, astigmatism

LASIK: Revolutionising correction of refractive errors
LASIK, an unprecedented advancement in eye care, offers people a safe and simple opportunity to see the world clearly, minus the inconvenience or discomfort of scratched or lost contact lenses, or the blocked side vision of spectacles. In simple term LASIK is a revolutionary laser technique for correction of refractive errors.

Ferguson said he went to three doctors seeking a panacea for the headaches. One suggested that LASIK surgery probably would solve his eye problem and just might curb the headaches.

Opening Your Eyes To LASIK
More and more people are going under the laser to shed their glasses and contact lenses. So the Eye Surgery Education Council has issued new guidelines to help patients determine whether they could be candidates for laser eye surgery.

Are you near-sighted? Far-sighted? LASIK eye surgery could rid you of your glasses. But if fear of going under the blade is stopping you -- stop worrying. Now, a new blade-free approach.

affects the focus of both near and distant vision if the cornea either curves and/or flattens unevenly.

Most eye doctors will probably recommend other types of vision correction before turning to eye surgery or a related procedure. Naturally, wearing glasses or contact lenses is the first alternative. As opposed to other eye diseases, these refractive errors are not necessarily progressive conditions, and may actually get better in middle age for some people. And there are some doctors who reject the need for eye surgery, claiming that your eyes are still healthy even with nearsightedness or farsightedness. The best approach for you is something that you will have to decide after a complete, careful evaluation of your eyes, your overall health and your expectations for the surgery.

Part of the process of determining if you're a candidate for eye surgery involves considering the particular risks it presents for some people. Your surgeon may advise you against this surgery if you have an immune system disease that reduces your capacity to heal after surgery. With an "autoimmune disease" like rheumatoid arthritis, or an "immunodeficiency disease" such as HIV, the risk of infection and other complications following laser eye surgery is greater.

Other conditions that may affect your suitability for the procedure are conditions that cause dry eyes, as they are likely to obstruct and delay the healing process. Doctors report that extremely uneven or abnormally shaped corneas may complicate matters, and if your vision is progressively worsening from other conditions you may be considered ineligible for laser eye surgery. In fact, even deep-set eyes and other facial-bone anomalies can make the procedure both riskier and more difficult.
