How does it work?
Orthokeratology works by using specially designed rigid gas-permeable (RGP) contact lenses to gently reshape the curvature of the eye overnight, creating a slightly flatter cornea. It is the cornea which plays a key role in creating a sharp optical focus.
Upon waking, the slight change in corneal curvature is enough to create clear, sharp vision for the duration of the day, and so can temporarily reduce or correct your short sight.
Unlike laser eye surgery, it is non-invasive and reversible, making it a good choice for anyone who has considered refractive surgery, but are concerned with the risks.
