Eye Surgery Cases |
When a person decides to undergo vision correction to minimize or
eliminate nearsightedness, farsightedness or astigmatism, it is to
laser eye surgery that they look. Some people are afraid of such
procedures and think of cosmetic surgery to be just a making money facility and they prefer wearing
contact
lenses. The advantage of eye surgery is that it helps you to correct
your vision once forever.
The procedure involves using a laser to reshape the cornea of the eye.
Eye surgery for vision correction is needed when light entering the eye
does not travel properly to the retina located at the back of the eye.
Because of slight distortions in the cornea, the light skews so that
the retina picks up blurred images. The person may see well up close,
but not at a distance. This is called nearsightedness and is the one
condition most easily corrected by laser surgery. Laser eye surgery is
also successful in treating astigmatism, the condition of seeing images
that are twisted. Farsightedness can be successfully treated in
patients who are under 40. With older people who typically become
farsighted as a result of aging, correction is often only partial.
The most common laser vision correction procedure currently in use by
millions is called LASIK. That is short for Laser-assisted In Situ
Keratomileusis. In this procedure a thin slice of tissue is peeled back
from the surface of the eye to form a flap. This flap is folded back so
that the remainder of the cornea is exposed to the laser. Using short
bursts of energy from the laser, the cornea is reshaped. A tiny layer
of tissue is removed in the areas shown to need it, (by extensive
mapping) to correct the vision. The flap is then put back in place and
seals itself there. No stitches are required at all. The entire
procedure takes about 15 minutes per eye. The only anesthesia needed is
eye drops. After care consists of eye drops for moisture as the surgery
typically caused the eye to be dry for a few weeks. Antibiotic eye
drops are also used to prevent any infection.
