How does Orthokeratology work?

When an Orthokeratology / OrthoK / iGo / Paragon Corneal Refractive Therapy™ lens is inserted overnight, the central part of the retainer lens (which covers the pupil) exerts a gentle moulding effect on the surface cells of the cornea (the epithelium). This causes the epithelium to flatten, and thin slightly, which changes the refractive power of the cornea. It is this change in corneal shape & power that corrects the short-sightedness.

Clear Daytime Vision
Once the retainer lens is removed in the morning, the vision is clear.

Reversible
The flat corneal shape very slowly reverts back to its normal shape, but normally only at a rate of -0.25D per day. If the lens is permanently removed, then the prescription will eventually revert back to the normal pre-treatment prescription over the course of a few weeks. The beauty of this procedure is that it is fully reversible & adjustable to cope with any changes in prescription in the future.

Safety
There is no evidence in scientific literature to suggest any permanent changes or damage to the cornea, making it a very safe, non-invasive method of vision correction when compared to laser surgery. There is a risks of eye infection and keratitis from using all types of contact lenses, and the risk of Orthokeratology eye infection appears to be comparable.
