Corneal Refractive Therapy
Corneal Refractive Therapy (CRT), also known as, Gentle Vision Shaping, uses specifically designed contact lenses which act as a vision retainer to gradually reshape the front surface of the eye (the cornea) during sleep. This gentle and gradual reshaping of the eye eliminates or reduces nearsightedness (myopia) or astigmatism.
The principle is similar to the use of a dental retainer to realign crooked teeth. The contact lenses are only worn at night while sleeping and removed upon awaking. This procedure will provide clear vision during the day without the use of eyeglasses or contact lenses! The retainer contact lenses are comfortable and simple to care for.
Corneal Refractive Therapy is a safe and effective way to temporarily reduce nearsightedness in adults and children. It is approved by the FDA and has been utilized by eye doctors for many years. We are pleased to offer this technology to our patients.
The main purpose of CRT is to eliminate the need for contact lenses or eyeglasses during waking hours. Many adults enjoy activities or work in conditions that are not suitable for wearing traditional contact lenses or eyeglasses. Sports enthusiasts who enjoy golfing, skiing, biking, or swimming are free to get back to doing what they love and not worry about the hassle of their glasses or contact lenses. People who work in dusty or dirty environments can be more comfortable throughout their day. Even people who suffer from dry eye, allergies, or other eye conditions can be relieved of the irritation of traditional contact lenses using Corneal Refractive Therapy.
Additionally, CRT has several advantages over LASIK. Unlike laser surgery, CRT can be performed on patients of any age regardless of whether their prescription has stabilized or not. The process is also pain free and results can be seen immediately the next morning. Lastly, and perhaps most importantly, CRT is reversible while laser surgery is not.
CRT is a great alternative to eyeglasses and contact lenses for children and teenagers. Many kids are unable to wear glasses while playing sports like football or hockey. Wearing the retainer contact lens at night allows our student athletes to be able to see the smartboard in class and compete in the big game with out worrying about the hassles of contact lenses and eyeglasses.
CRT has been shown to slow the progression of nearsightedness. Many parents are concerned that their child will keep getting more nearsighted each year, requiring stronger and stronger glasses. Over time, doctors have observed less vision decline in patients using CRT lenses compared to those using eyeglasses or soft contact lenses.
Is everyone a candidate for CRT?
Not every patient is a good candidate. The procedure works best on mild to moderate amounts of nearsightedness or astigmatism. Our Doctors can help determine if you are a good candidate at your annual exam.
Can any Doctor perform CRT?
No, our Doctors have received special training and have the necessary diagnostic equipment, computer software, and expertise to perform CRT.
I’ve never heard of CRT, is it new?
No, it has been around for decades. It is also referred to as orthokeratolgy (ortho-k).
Is CRT safe?
Yes, CRT is very safe and completely painless. The FDA approved the procedure in 2002.
How much does CRT cost?
The entire program which includes two sets of contact lenses is about 1/3 the cost of LASIK surgery. For more
