A Helper for Vision Impairment: Lasik Eye Surgery

Eyes are organs that detect light, and convert it to electro-chemical impulses in neurons. They constitute one of the most important organs in body. For mankind, eyes enables them to view beauties in the world and gift them a life of happiness. However, there are so many intra- or extra- factors that would cause problems to eyes. Vision impairments and eye diseases are commonly seen in modern society, due to fact that people have to use their eyes more everyday and some unhealthy living habits are also contributors to those eye problems.

While the modern life brings us troubles to eyes, it also brings solutions accordingly. The lastest technological advancement has made Lasik eye surgery a simple alternative to deteriorating eyesight and problems, such as nearsightedness, farsightedness and astigmatism, etc.. In normal circumstances, the retina, one part of the eye, changes images that come into the eye into electrical impulses that the brain understands, and when the retina goes wrong, the vision would get impaired. For nearsighted sufferers, they would feel hard to view objects far clearly, while for the farsighted ones, they find close objects blurred. One of the typical symptoms of astigmatism is that the patients see double images, resulting from the vision disorder caused by the eyeball not being round. The eye can hardly focus on the object.

Having eyesight problems makes one ruffled. For one thing, it is a hassle to wear prescription glasses or to wear contact lenses; on the other hand, for those with active lifestyles, wearing glasses can be a potential danger. For example, when one is playing basketball one day, the ball may possibly fall on the glasses, and get is broken. The chips may hurt eyes and faces. Fortunately, for them, here is another good choice. Lasik, whose full name is laser in-situ keratomileusis, allows the patients to regain their normal eyesight within minutes. It makes such an achievement by reshaping the out-of-shape cornea with a special laser.

During the procedure, the surgeon will use local anesthetic, as a result, the patients will feel no pain during the whole surgery. But not everyone is a good candidate for Lasik. Usually people with a thick cornea and those who are short sighted or suffering from mild long sightedness are expected to get the best results following the surgery. So when you are preparing to correct vision by a Lasik, to have an eye examination is advisable.
