Patient Evaluation for Orthothokeratology Lens

• Chung JK

Abstract

Orthokeratology lenses are approved for temporary reduction of myopic refractive error by flattening the corneal curvature. Orthokeratology lens used to slow down the progression of myopia in children by limiting axial enlongation of the eye. It is very important to select proper candidate to achieve desired correction of refractive error. Several essential ophthalmologic examinations consist of slit-lamp examination, keratometry, corneal topography for initial lens selection and help to predict clinical outcome. This article reveals the pre-fitting evaluation, its interpretation, and patient selection to assure treatment effect.
