WHAT IS CORNEAL REFRACTIVE THERAPY (CRT)?
Corneal Refractive Therapy uses specifically designed retainer lenses to gently and gradually re-shape the front surface of the eye (the cornea) to eliminate or reduce nearsightedness (myopia) or astigmatism. The CRT lenses are similar to contact lenses and are usually worn at night while sleeping. They are then removed upon awakening to provide clear vision without the use of glasses or contact lenses! The CRT lenses are comfortable and very easy to care for.
I’VE NEVER HEARD OF CRT. IS IT NEW?
Methods to re-shape the cornea have been attempted since contact lenses were first fit. The process used, also referred to as orthokeratology, would take years to complete. For this reason, many doctors and patients elected not to participate in orthokeratology. With advanced diagnostic technology used to measure the corneal shape and new materials being used for vision retainers, CRT is now a viable alternative for many nearsighted or astigmatic patients.
HOW MUCH DOES CRT COST?
There is a one-time initial fee for CRT. Once the program has been completed, you will continue to have annual eye examinations and maintenance checkups.
HOW OFTEN SHOULD THE LENSES BE REPLACED?
Manufacturers suggest replacement is one year, although we have found many of our patients prolong the life to 2 years by super-cleaning their lenses in our office every 6 months.
DO ALL EYE DOCTORS PERFORM CRT?
No. CRT does not work for every patient and needs to be performed in a very exact and meticulous manner. Drs. Fauria and Pirrone have extensive experience and have performed this technique since 2002. In addition, we have the necessary diagnostic equipment and computer software to safely perform CRT.
WHEN IT COMES TO EYES, I’M VERY CONCERNED. IS IT SAFE?
CRT is very safe and we utilize FDA approved materials. It is safe for children and adults and is an excellent alternative for children who are just first becoming nearsighted.
WILL CRT HELP STOP MYOPIA?
In our experience, and in many of the latest studies, the progression of myopia is greatly reduced if not stopped entirely. Both Dr. Fauria and Dr. Pirrone have patients fit in 2005 and 2006 who have had no myopia progression. Studies are showing a much higher incidence of myopia in the United States. The prevalence of myopia has doubled to more than 40% in the past 30 years. This affects ocular health as patients grow older. At 3.00 diopters of myopia the risk of Posterior Subcapsular Catararact (PSCC) triples and the risk of Myopic Maculopathy (MM) and Retinal Detachment (RD) are nine times greater than someone without distance glasses. At 5.00 diopters of myopia the risk of PSCC is 5 times greater, a 21 times greater risk of RD and 40 times greater risk of MM. Higher myopia levels bring even higher risks. CRT Therapy keeps myopia in check, reducing these risks.
