            Corneal Refractive Therapy

            Corneal Refractive Therapy allows nearsighted (Myopia) patients to reshape the cornea by sleeping with custom contact lenses and see with clear vision for a full day without the use of eyeglasses or daytime contacts. On the surface this sounds like new science. It’s not.

            This technology has been around since the early 1940’s. It has been known that the cornea can be reshaped with “firm” contact lenses with consequential improvements in vision.

However, what’s relatively new is the ability to digitally photograph the surface of the cornea. Then feed that digital data into digitally controlled lathes to manufacture contact lenses to sub-micron levels of accuracy with repeatability.

In addition, there are new and improved gas permeable materials available with higher “Dk” ratings that have a greater degree of oxygen permeability (essential for good eye health) .

With these three advancements, patients with Myopia (nearsightedness) are now able to sleep with the new “eye retainers”, remove them in the morning and achieve up to a full day (or more) of clear vision.

In June of 2002, the Food and Drug Administration has granted approval for the overnight wearing of corneal reshaping lenses to Paragon Vision Sciences, Inc. andin 2004 to Euclid systems Corp.
