Summary: Orthokeratology is a procedure that uses gas permeable (GP) contact lenses to reshape the cornea in order to temporarily reduce, modify, or eliminate myopia and astigmatism to achieve a transient improvement in unaided visual acuity. The mechanism of orthokeratology is not quite clear. Certainly, the effects of contact lenses on the corneal epithelium have been well documented. In this paper review of the methods of corneal shape changing after Ortho-K lenses wear is presented.

Keywords: orthokeratology, gas permeable contact lenses, methods.
