LASIK surgery - the best way to correct vision

LASIK is the most well known surgical procedure willful to reduce a person's dependency on glasses or contact lenses. LASIK (Laser-Assisted In Situ Keratomileusis) provides vision correction by permanently changing the shape of the cornea and changing it's focusing power. In LASIK surgery the corneal tissue is precisely removed and the cornea is reshaped. In the USA, the Food and Drug Administration (FDA) has approved the use of LASIK in correcting vision since 1998, for the treatment of myopia, hyperopia and astigmatism. LASIK is not recommended for the persons which are in their early 20s or younger, the persons which have diabetes, are pregnant, or are taking medications such as steroids. Also, people who had glaucoma suspect, or ocular hypertension, eye diseases or previous eye surgeries should not have LASIK surgery. There are a few indicators of risk that have to be taken into consideration when a person decides to have LASIK surgery, such as: large pupils, thin corneas, previous refractive surgery, dry eyes (LASIK surgery aggravates eye dryness). Before you have LASIK surgery you have to stop using contacts for 1 to 4 weeks advance surgery to permit the cornea to return to it's initial shape. During the LASIK surgery patients are given an anesthetic and generally they feel no pain, but there are a few cases when they suffer some discomfort. You can have LASIK surgery for both eyes at the same time if your health condition allows it. LASIK surgery regularly takes about 5 or 10 minutes per eye. The newest technology in LASIK is the wavefront laser, approved by the FDA in 2002, which sends a wave of light to the retina that helps producing a 3-D map oh the eye's visual system. During the LASIK surgery complications can appear in very few cases, for less than 1% of patients. You can be a candidate for LASIK surgery if you are at least 18 years old and you had no radical changes in vision over the past year. In addition, for persons with severe vision problems LASIK may not be an option. After having a LASIK surgery there is a small chance to lose vision, for the patients who were among the persons for whom the LASIK was not indicated. Also, after the LASIK surgery there were patients who had blurred vision, bad night vision and diminished contrasts. Generally, these problems can be resolved by a new treatment.
