For a
person to see clearly, the cornea and the lens must refract (or bend,
in simpler terms) light rays so they focus on the retina, the layer
of light-sensing cells that occupy the back portion of the eye. The
retina is what converts the light rays into impulses that are sent to
the brain, where they are identified as images. If the cornea and
lens don't focus light into the retina properly, the image you see
will be blurry. This inability of the cornea and the lens to do their
job is called refractive error.
Refractive
errors are usually caused by an imperfectly shaped cornea, lens, or
eyeball. Examples of refractive errors are myopia (nearsightedness),
hyperopia (farsightedness), and astigmatism. For these eye
conditions, LASIK eye surgery offers a viable solution.
LASIK
is short for laser-assisted in situ keratomileusis. In a LASIK
procedure, a low-powered laser is used to reshape a patient's cornea
to improve the way the eye focuses light rays into the retina. Only
ophthalmologists can perform this type of eye procedure. Ask your
medical doctor for a referral to a licensed ophthalmologist who
performs LASIK.
LASIK
is an outpatient procedure, which means you can go home directly
after the ophthalmologist performs the procedure on you. Healing is
relatively fast, but you may want to take a couple of weeks from work
after the surgery to allow your eyes to heal properly.
