Corneal Refractive Therapy is a non-surgical process which
reshapes the cornea of the eye utilizing special contact lenses and thereby
reduces the dependence upon eyewear. The procedure was discovered over 40 years
ago when eye doctors noticed that some contact lens wearers' vision improved
after wearing their lenses. Initially, only old-fashioned, hard contact lens
material (PMMA) was used. Corneal Refractive Therapy is best suited for myopia
(nearsightedness), but studies are |
 |
|
underway for hyperopia
(farsightedness). The inherent problems associated with
that plastic prolonged the procedure for up to two
years. Now, with the advent of space-age polymers,
computer-assisted lathes, and great technological
advancements in the procedure, it is possible to achieve
reduction of myopia in a matter of weeks to a few
months. This procedure is know as Corneal Refractive
Therapy. |

Cornea
The cornea makes up about two-thirds of the eye's total power to
focus the light precisely on the retina (receiving screen) which is
located in the back of the eye. By slight modifications in the shape
of the cornea, clear functional vision may be restored for a period
of time. |

Corneal Refractive Therapy is
accomplished with a contact lens device that may be
referred to as |
|
|
a corneal mold. The mold is similar to a contact
lens in its appearance. The mold is working as it is worn, whether
you are sleeping or awake. The procedure takes just hours (in mild
cases) to a couple of weeks (in very difficult cases) to reach good
functional vision. At that point, the mold-wearing time is gradually
reduced until a minimal-wear time is established that maintains the
corneal shape and good functional vision. |
