Myopia Management contact lenses are designed to correct your child’s vision by slowing the process of elongation and enlargement of the eyeball. There are various types of Myopia Management lenses available currently. Most of our patients opt for the CooperVision MiSight® 1 day, daily disposable Myopia Management contact lenses. Another other option is orthokeratology (Ortho-k) lenses that are worn only when asleep.
A relatively new option, these are often considered to be the most popular choice with our patients because they require no cleaning or storing at the end of the day. The lenses are called dual focus lenses meaning that they have different focusing powers for the centre and the periphery of the lens. By changing the focus of light falling on the periphery (edges) of the retina, you can reduce that stimulus for the eyeball to grow and become more myopic. So the lenses do two things. Firstly, they make the child see clearly by correcting the myopia in the centre of the eye and secondly, they have special optics at the edges which changes the focus of the light there, which in turn slows the progression of growth.
Ortho-K lenses were designed originally many years ago to be worn at night while people sleep and avoid the need to wear and glasses or contact lenses during the day. They are great for children who don’t feel confident to wear lenses at school or who take part in sport like swimming, where contact lenses wear is not possible. They work by reshaping the eyeball as the child sleeps allowing them to see clearly by day. It was only accidentally discovered more recently, that when the contact lens reshapes the eye it creates the same dual focus as the daily disposable lenses, correcting the central vision and altering the peripheral focus of the eye to slow the progression of eye growth.
