LASIK
Light and images are
focused, or refracted, by the cornea, the clear front window of the eye.
Vision is clear if the cornea and lens focus the image precisely on the
retina. The retina is a layer of light sensitive cells that line the
back of the eye. When images are not focused precisely onto the retina a
refractive error occurs.
If light
and images are focused in front of the retina, distant objects appear
blurry. This is called myopia or nearsightedness. If images are focused
beyond the retina, nearby objects appear blurry. This condition is
called hyperopia or farsightedness. If the cornea has unequal curves,
images are distorted because light focuses on more than one point in the
retina. This is known as astigmatism.
Glasses
or contact lenses correct refractive errors (myopia, hyperopia and astigmatism)
by adding or subtracting refractive power. Refractive surgery is intended to
improve vision by permanently changing the shape of the cornea and thereby reducing
the dependence on glasses or contact lenses.
LASIK, or
Laser in-Situ Keratomileusis, is a remarkable laser technology which is
reshaping the corneas and thereby reducing or eliminating the need for
glasses or contact lenses for hundreds of thousands of Americans every
year. We also offer Wavefront (Custom) LASIK.
LASIK has
become the refractive correction procedure of choice because of the many
benefits this type of surgery provides, such as:
