The principle upon which CRT is based is quite sound and simple. Basically, an individual requires spectacles (glasses) to see when their cornea is too flat, too steep or out of round in relation to the other elements or parts of the eye. The cornea makes up about two-thirds of the eye's total power to focus the light precisely on the retina (receiving screen) which is located in the back of the eye. By making modifications in the shape of the cornea, clear functional vision is achieved when the lenses are removed. 

This is accomplished with a specially designed therapeutic contact lens. It is similar to a regular contact lens in its appearance and the way it feels while being worn. The lens is working whenever it is worn, whether you are sleeping or awake. Improvement of vision is seen in just hours (in mild cases) to a few months (in very difficult cases).The lens is worn until the best vision is achieved. At that point, the wearing time is gradually reduced until a minimal-wear time is established that maintains the corneal shape and good functional vision. The cornea can easily be fine-tuned for the rest of one's life by minor modifications in the retainer lens. The retainer lens must be worn on a regular basis to maintain the improvement in vision. 

Dr. Hill has helped many nearsighted people enjoy freedom from glasses or contacts during their waking hours.
