Ortho-K and Overnight Vision Correction
An alternative to laser surgery, Ortho-K – short for orthokeratology and also known as overnight vision correction (OVC) – is a service that we offer to patients who prefer not to wear spectacles or contact lenses during the day.
Ortho-K treatment requires you to wear specially designed contact lenses overnight and works by altering the surface of the eye to correct your prescription. The lenses are then removed in the morning, leaving you with clear vision that is temporarily effective but fully reversible.
Overnight vision correction gives your eyes the freedom to breathe.
Made from a material that allows high levels of oxygen permeation, Ortho-K lenses are specifically designed for you to sleep in without having a drying effect. Leaving a residual window over your cornea that corrects short-sightedness, the effects last throughout the day and remove the need to wear glasses or daytime lenses.
OVC provides a less invasive alternative to laser eye surgery, whilst freedom from spectacles and contact lenses means that sports can be enjoyed more conveniently and eyes are less irritated during the day.
Having been used for vision correction for more than ten years, Ortho-K has also proven to be a highly effective treatment for short-sightedness in children. Recent research has even shown that it could help slow the progression of myopia in younger patients.
