Eye Surgery has become a mainstream method of vision correction, and this article will explain the advantages and disadvantages of three different methods being offered to the medical consumer. Lasik Eye Surgery LASIK is the acronym for Laser-Assisted In Situ Keratomileusis and is an eye surgical system which permanently corrects vision by removing a thin layer of the cornea. This procedure works best on patients with moderate to high degrees of myopia (nearsightedness), low to moderate degrees of hyperopia (farsightedness) and astigmatism associated with myopia, and who have thick corneas. It is the most well-known surgical vision correction method. People with normal eye sight see objects clearly because images are brought into a correct focal point by the cornea and lens of the eye.

Ideally, the cornea’s curvature is evenly matched to its length in a normal eye. People with astigmatism, myopia or hyperopia have irregularly shaped corneas, so the objects seen are not focused properly. LASIK changes corneal shape by precise removal of corneal tissue, and by doing so corrects the eyes’ focusing power. There are, however, risks to LASIK eye surgeryThere is a remote chance of complete loss of vision. If this happens, it is usually because the patient had a pre-existing condition which should have precluded the surgery in the first place, such as pregnancy, cataracts, arthritis, diabetes, glaucoma, or lupus. People with large pupils are also poor candidates for LASIK. Dry eye syndrome will be aggravated by this procedure. A few patients complain that they permanently see "ghost" images, have blurred vision, diminished contrast and bad night vision. When LASIK was first introduced,…Read more information
