Even though LASIK eye surgery can eliminate your need for wearing eyeglasses or contact lenses, the procedure does come with some risks. For example, if you suffer from presbyopia, LASIK surgery can help you achieve clear distance vision, but it can also impair your ability to see nearby objects. Generally, LASIK eye surgery is most appropriate if you have a moderate degree of nearsightedness, farsightedness, or astigmatism.
In order to be a good candidate for LASIK eye surgery, you need to be at least 18 years old with no history of corneal disease. The procedure can help correct nearsightedness, a condition in which you are able to see nearby objects clearly, but far-away objects appear blurry. This condition occurs if your eyeball is too long or if the cornea has too much of a curvature. If you suffer from a moderate degree of nearsightedness, an ophthalmologist can use LASIK eye surgery to reshape the cornea.
Also known as hyperopia, farsightedness is a condition in which you are able to see distant objects clearly, but can’t properly focus nearby objects. This is the result of the eyeball being too short or the cornea not having enough curvature to correctly focus incoming light. LASIK eye surgery can help reshape your cornea , so that it has the optimal curve to allow light to correctly focus.
Astigmatism occurs if your eyes aren’t completely round. As light enters your eyes, it is refracted unevenly, which means only one part of an object can focus at a time. This causes distant objects to appear blurry and wavy. If your eyes are healthy and free of retinal problems, then LASIK eye surgery can refocus your corneas, so that light is distributed evenly and objects focus clearly.
The best way to determine whether or not you are a good candidate for LASIK eye surgery is by meeting with an ophthalmologist.
