Orthokeratology is shortened as "ortho-k" and called corneal reshaping (CR) or corneal refractive therapy. Orthokeratology refers to usage of gas permeable contact lenses that reshape the cornea and reduces refractive errors such as myopia, hyperopia and astigmatism. New ortho-k lens designs are available for farsightedness and presbyopia. Research also stated that orthokeratology lens designs slowers the progression of myopia.
