Paragon CRT® is a specially designed FDA-approved therapeutic contact lens worn while sleeping that gently and safely reshapes the cornea without permanently altering its physiology - which is important as the eyes of children and teens are still maturing.
In the myopic eye (difficulty seeing at a distance), the focusing power is too great. Light focuses in front of the retina, making distant objects appear blurry. When eyeglasses or contacts are worn, light is focused on the retina so you can see clearly.
Today, Paragon CRT provides a new option for patients with myopia. Paragon CRT lenses correct myopia, with or without low to moderate astigmatism, by gently and safely reshaping the cornea while you sleep. When the Paragon CRT lenses are removed in the morning, the treated cornea allows light to focus on the retina. The result is clear, natural vision for all or most of your waking hours. And yes, if you get up during the night, CRT lenses will enable you to see clearly with the lenses on! CRT provides 24-hour vision!
Q. Will CRT® improve my child’s vision better than traditional glasses or contacts?
A. The treatment results should equal the vision correction provided by traditional glasses or contacts. CRT is designed to temporarily treat nearsightedness (myopia), however studies are ongoing to determine if wearing lenses such as CRT help to slow or even stop the progression of nearsightedness. CRT may provide a solution that may not be available through the use of traditional glasses or daytime contacts.
Q. How long does it take to start working?
A. Most patients see dramatic improvement in the first few days, with complete vision correction, generally, within 7-10 days.
Q. Is CRT safe?
A. Yes. Part of the safety profile lies in the fact that if your child stops wearing CRT lenses, their vision will return to previous levels. In addition, no adverse events were reported during the FDA clinical trial* and available data suggests that CRT lenses have a similar safety profile as other contact lenses that are approved for wear during sleep.
*Additional safety information is available in the CRT package insert.
