The basic purpose of CRT is to improve visual function. For many, this is a safe, non-surgical approach to improving and restoring vision.
In people of all ages with increasingly stronger prescriptions, CRT can slow down or stop the need to get stronger glasses. Research shows that the effect may alter the person's long-term prescription
Let's first understand how CRT works to correct Myopia. In the myopic eye, the focusing power is too great. Light focuses in front of the retina, making distant objects appear blurry.
Today, Corneal Refractive Therapy provides a new option for patients. CRT lenses correct myopia, with/without low or moderate astigmatism, by gently reshaping the cornea while you sleep!
Not everyone is a candidate for CRT therapeutic lenses. Since there are many variations in patient physiology and visual needs, the decision for CRT, at any age, can only be made after a thorough exam.
