Abstract:
Orthokeratology is the way to correct the myopia or astigmatism by flattening or the central cornea with specialty lenses. The range of correction is from − 2.50 to − 4.00 diopters after 10 days of fitting. The designs is constructed with flat base curve radius, steep reverse curve, flat alignment curve, and peripheral curve. This multi-cuve design enabled the orthokeratology lenses to stay on the cornea stably and effectively. Recently, the application of orthokeratology is extending to hyperopia and presbyopia. In the future, the amount of correction and the application of orthokeratology will increase more and more.
