Today, Corneal Refractive Therapy provides an option for patients. Paragon CRT lenses correct myopia, with/without low or moderate astigmatism, by gently reshaping the cornea while you sleep.

Corneal Refractive Therapy uses specially designed vision retainers to gently and gradually reshape the front surface of the eye (the cornea) to eliminate or reduce nearsightedness (myopia) or astigmatism. The principle is similar to the use of a dental retainer used by an orthodontist to realign crooked teeth. The vision retainers are similar to contact lenses and are only worn at night while sleeping. They are then removed upon awakening to provide clear vision without using glasses or contact lenses! The retainers are comfortable and very easy to care for.
