What is a more Technical Definition of Corneal Refractive Therapy (CRT®)?
Corneal refractive therapy is a FDA approved contact lens corneal reshaping system used to reduce or temporarily correct myopia. The method was approved in June, 2002 by the FDA for correction of up to –6.00 D of myopia with up to –1.75 D of cylinder. The term Corneal Refractive Therapy is a FDA approved indication and is in the public domain, whereas, the acronym CRT is a registered trademark of Paragon Vision Sciences. CRT describes a method of correction for myopia by use of overnight wear of specially designed gas permeable lenses that redistribute and compress the corneal epithelium such that central epithelial thickness is decreased while peripheral epithelial thickness is increased. The reconfiguration of the epithelium results in redistribution of the refractive power of the cornea. The process is reversible when contact lens wear is discontinued. Lens selection in guided by the patient refraction, corneal curvature measurements, and confirmation of lens fit by evaluation of th
