Orthokeratology (OK) is a clinical technique that uses specially designed rigid contact lenses
to reshape the cornea to temporarily reduce or eliminate refractive error. This article reviews …

Orthokeratology has undergone drastic changes since first described in the early 1960s. The
original orthokeratology procedure involved a series of lenses to flatten the central cornea …
