The name
"LASIK" is short for Laser In-situ Keratomileusis. LASIK is
used to treat low to high amounts of nearsightedness, astigmatism,
and farsightedness. LASIK combines the computer controlled
precision of the Excimer Laser with the benefits of another
type of refractive surgery called Lamellar Keratoplasty (a
procedure where an instrument known as a microkeratome makes
a small flap in the outer layer of the cornea).
Myopia
Normal
vision - to see clearly, light rays are focused on the retina
by both the cornea and the lens of the eye. In a myopic eye,
commonly referred to as "nearsighted" (place
cursor over image), light rays from objects are
focused in front of the retina causing images - particularly
at a distance - to be blurred.

A
thin corneal flap is created using a special instrument
called a microkeratome |
|
|
The
Excimer laser pulse, after being preprogrammed for the
appropriate myopic correction, is applied to the corneal
bed. |
|
|
The
"flap" is returned to its original position of a quick,
natural recovery. |
|
|
Following
LASIK treatment for nearsightedness, the curvature of
your central cornea is flatter. Light rays from viewed
objects are focused on the retina. |
Result
After LASIK for Myopia Surgery
Before
LASIK treatment for nearsightedness, light rays from viewed
objects are focused in front of the retina. After the LASIK
treatment, the "flatter" cornea allows light rays to bend
in such a way as to become focused on the retina.
Over
96% of patients treated with the LASIK procedure at the Sunetra
Eye Centre are no longer required to wear their glasses or
contacts. However, individual results cannot be guaranteed.
