Corneal Refractive Therapy – CRT

Corneal Refractive Therapy (CRT) 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.  CRT is a safe, reversible and affordable alternative to refractive surgery.
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.
CRT 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 very happy to offer this technology to our patients.
Adults
The main purpose of GRT 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 CRT.
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. 
Teenagers
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 soccer.  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 without worrying about the hassles of contact lenses and eyeglasses. 
Children
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 GRT lenses compared to those using eyeglasses or traditional contact lenses.

Frequently Asked Questions about CRT:

Can any Doctor perform CRT?
No.  Dr. Freeman has received special training and has been certified since 2002 to fit CRT lenses.  Our office has the necessary diagnostic equipment, computer software, and expertise to perform CRT.
