CRT (Corneal Refractive Therapy)

Corneal refractive therapy (CRT) is a non-surgical means of minimizing nearsightedness in vision patients. Also known as orthokeratology, CRT uses gas-permeable lenses similar to traditional contact lenses to reshape the cornea at during sleep. During the day, patients can experience a better natural vision without the aid of corrective lenses. The unique design of CRT lenses temporarily reshapes the eye, providing results that can last as long as two to three days.
