What is orthokeratology?

Eye vision option: Use of hard, gas-permeable contact lenses worn at night to "reshape" the cornea for people who don't want/need to wear regular contact lenses. Usually for lessor corrective requirements and much be done daily (night).

Non-surgical vision: Orthokeratology refers to using rigid contact lenses (that are permeable to air) at night to "reshape" the cornea leading to corrected vision.

Eye reshaping: Firm oxygen permeable lenses specifically designed to reshape the corneal surface are worn only during sleep. These can markedly reduce myopia (nearsightedness) and some astygmatism as well.
