CRT
In 2002, the FDA approved a non-surgical procedure called Paragon CRT, which stands for Corneal Refractive Therapy. With this technique, a specially designed retaining contact lens is placed in the eye before going to sleep, and is removed in the morning.
Over the first three to five days, the corneal shape is gently modified so that the patient has excellent distance vision during daytime activities (without the use of the lens). As long as one wears the retaining lens while sleeping, one should retain the benefits of excellent vision during the day. Your doctor will evaluate you before fitting with the specialized lenses.
The general follow-up is one day, one week, two weeks, one month, three months, and six months. The overall satisfaction rate with this method has been excellent.
There are limitations based on the degree of prescription and the amount of the astigmatism any given patient has, but your doctor will discuss with you whether you are a suitable candidate. This does not preclude refractive surgery or LASIK at some point in the future.
Because it is a non-surgical method, the pricing is significantly lower than traditional refractive surgery.
