Orthokeratology is the “reduction, modification or elimination of a refractive error by the programmed application of contact lenses”.

Basically you wear a contact lens overnight which gently moulds your cornea, reducing your prescription.

In most cases this means that you can perform normal functions without glasses.

Currently orthokeratology is being used in the control of moderate myopia (shortsightedness), however new developments mean that soon we will be able to treat astigmatism and perhaps hyperopia (longsightedness).
