Orthokeratology is the use of a specially designed therapeutic contact lens that gentley molds the cornea during sleep. You remove the lenses when you awake and are able to go throughout the day without any other correction. The result for you is great vision 24 hours a day - without the lenses during waking hours and while they're in at night - with correction of myopia (nearsightedness) and myopia with astigmatism.
