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
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.
