Corneal Refractive therapy (CRT)

Author: Alexander Mao |


Corneal refractive therapy (CRT) is a non-surgical treatment option for people suffering from mild to moderate presbyopia, nearsightedness, farsightedness, or astigmatism. CRT offers a legitimate alternative to laser vision correction for many people. This procedure uses specially designed contact lenses, which are prescribed to reshape the surface of the cornea and reduce or eliminate the need for glasses or regular contact lenses. CRT treatment involves changing the curvature of the cornea by temporarily molding its shape using a gas permeable contact lens. The central portion of the lens fits closer to the eye than a standard contact lens - exerting gentle pressure. The outer part of the lens surrounds the central visual zone and is farther away from the cornea allowing room for the cornea to change shape. By changing the curvature of your cornea, this treatment refocuses light onto your retina, resulting in clearer vision. CRT is completely reversible and non-invasive; if you stop wearing the molds your cornea will return to its original shape. In the past, the only FDA-approved CRT systems were worn during the day and proved to be very safe and effective. More recently, the FDA has approved the latest in CRT technology with an overnight lens that works for the eyes in a similar way that dental retainers work for teeth. Make life without glasses or contact lenses a reality. Talk to your eye care professional today and find out if CRT is right for you.
