Orthokeratology-A Historical Summary and Update

Abstract

Objective: To present a comprehensive review of current and historical literature of orthokeratology treatment and lens
technology.
Methods: A summary of the history of orthokeratology lenses was compiled through literature research from a selection of
databases. A summary of contact lens materials, corneal topography and associated lens design is presented. The history of
orthokeratology is presented as well as developmental milestones since its inception. Orthokeratology appears to be a safe
form of vision correction.
Conclusions: Orthokeratology appears to be a safe form of contact lens correction for refractive errors. The advancement
in lens design, contact lens manufacture and corneal topography has greatly aided its acceptance as a treatment modality of
refractive errors.
