What types of vision disorders can be corrected using LASIK?
There are three types of vision disorders that can be surgically corrected. These conditions are called refractive errors. They include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.Top What is myopia? Myopia is nearsightedness. It occurs when the cornea is shaped too steeply or when the eyeball is too long. This means that the light entering the eye is focusing at a point in front of the retina instead of on the retina. A myopic eye can see near objects clearly. Distant objects are seen more clearly only with the aid of glasses, contact lenses or procedures such as laser vision correction.Top What is hyperopia? Hyperopia is farsightedness. It occurs when the cornea is too flat centrally and steeper at the edges. This means the images focus beyond the retina. In our youth, the natural accommodating (focusing) power of the eyes often compensates. As we age, our eyes become less able to accommodate. Farsightedness can be reduced or eliminated by glasses, contact l
