LASIK Surgery: An Overview
- Posted on: Apr 28 2015
LASIK, or laser in-situ keratomileusis, is one of the most common types of refractive surgeries that helps correct vision. During a LASIK surgery, the cornea is reshaped so that the light that travels through it is directed accurately to the position of the retina, thereby improving vision. A majority of the patients who undergo the refractive surgery can see clearly without corrective lenses or glasses following the procedure.
What Conditions Can LASIK Treat?
Myopia (nearsightedness) : Individuals with this condition can see objects that are close by clearly while experience difficulty in viewing far-off objects. This occurs either due to a more pronounced curvature in the cornea or a longer eyeball, which causes images to appear in front of the retina, and in turn blurred vision. Can be a hereditary condition\, and is seen to get worse with age.
Hyperopia (farsightedness) : In this condition, individuals are seen to either have a flat cornea or an eyeball with a relatively shorter length due to which the light rays are focused behind the retina, causing images of nearby objects appear blurred. This can be a hereditary condition sometimes, and is often seen at birth, although children with hyperopia are seen to overcome it as they grow up. Adults with hyperopia usually face difficulties while viewing objects close-up. The condition can sometimes make even distant vision appear blurry.
Astigmatism: This condition usually occurs due to an imperfect cornea shape. While an individual’s eye is generally spherical in shape, in individuals with astigmatism, the eye is no as evenly shaped, causing light to be refracted differently in different directions. This causes difficulties in viewing close and far objects, and allows them to focus on only selective parts of an object at a time.
