Volume 07, Issue 2

An analysis of the possibilities, benefits and risks of orthokeratology and how it will reshape future contact lens practice.

Introduction 

Overnight orthokeratology, corneal reshaping or vision-shaping treatment (usually generically referred to as simply orthokeratology) all refer to the technique that utilises reverse-geometry rigid contact lenses to change the shape of the cornea. This is a temporary, reversible technique. Currently it is most commonly used to flatten the central corneal curvature temporarily and reduce the corneal eccentricity and with it the patient’s myopia and with-the-rule astigmatism. In this article the current status of orthokeratology worldwide will be reviewed and the possibilities, benefits and risks analysed. What is the future of orthokeratology and will it reshape our future contact lens practice?
