title: Symposium: Clinical management of physiologic myopia. Role of orthokeratology: a perspective.
abstract: Orthokeratology is the reduction, modification, or elimination of refractive anomalies by the programmed application of contact lenses. A brief background is given on corneal changes induced by contact lenses fitted by normal and orthokeratology techniques. A common orthokeratology fitting method is described, results of inducing refractive changes are discussed, and a recently published study of this method of contact lens fitting and the author's personal observation on patients fitted by this technique are reported. Recent trends in orthokeratology and their possible effects on contact lens fitting are discussed, and a summarization of the effects of this contact lens fitting technique on myopia is given.
