L A S I K,
"laser assisted in-situ keratomileusis",
|
is a procedure that uses cool laser energy to
reshape the cornea.
LASIK candidates should be in good general health & present
with
a normal ocular health evaluation. The surgery, takes
about five to
ten minutes, with the laser application taking less than two
minutes |

The cornea is a
part of the eye that helps focus light to create an image on the
retina. It works in much
the same way that the lens of a camera
focuses light to create an image on film. The
bending and
focusing of light is also known as refraction. Usually the shape of the
cornea and the eye are not perfect
and the image on the retina is out-of-focus (blurred) or distorted.
These imperfections in the focusing power of the eye are called
refractive errors. There are three primary
types of refractive errors: They are myopia,
hyperopia and astigmatism. Persons with
myopia, or
nearsightedness, have more difficulty seeing distant
objects as clearly as near objects. Persons with
hyperopia, or farsightedness, have more difficulty
seeing near objects as clearly as distant
objects.
Astigmatism is a distortion of the image on the retina
caused by irregularities in the cornea or lens of
the eye. Combinations of myopia and
astigmatism or hyperopia and astigmatism
are common.
In LASIK surgery,
precise and controlled removal of corneal tissue by a
special laser, reshapes the
cornea changing its focusing power. LASIK is a procedure
that permanently changes the shape of the
cornea, the clear covering of the
front of the eye, by using an excimer
laser. A knife, called a
microkeratome, is used to cut a flap in the
cornea. A hinge is left at one end of this flap. The
flap is
folded back revealing the stroma, the middle section of the
cornea. Pulses from a computer-controlled
laser vaporize a portion of the stroma and the flap is replaced.

Lasik will not rid the
world of glasses but will reduce the need for them. For a general idea of what your vision
should be after Lasik refer to the chart.
Remember that many factors such as age, pupil size, and astigmatism have an effect on your
final vision. This chart is based on a clinical study of 612 patients.
As with any surgery there are certain risks involved and no guarantees of the exact
outcome. We recommend that you
educate yourself on the pros and
cons of Lasik before you make any decisions on surgery. |

Many of
our patients are interested in LASIK to
reduce their dependence on corrective lenses,
or eyeglasses. If you are a
good candidate,
one of these procedures
can be for you. |
