Myopia Control

SLOW THE PROGRESSION

(read in Chinese here 中国语言版本)

The scientific community's understanding of short-sightedness (myopia) has changed. Myopia used to be thought of as a condition which was unable to be influenced however we now know that with intervention we can significantly reduce the rate in which is progresses. 


The most common form of myopia occurs when the eye grows too long for its optical system comprising of the eye's cornea, lens and internal fluids. A fraction of a millimeter in excessive length can create a substantial amount of myopic blur. 


"Myopia control" is the process in which we use specialised contact lenses to make things clearer, but more importantly create a very different peripheral image which in turn tells the brain that the eye has reached its full size, hence slowing or in some cases halting the rate of further elongation.


There are three main forms of optical myopia control and one pharmaceutical form using an eyedrop known as Atropine. The three main optical forms are the Carl Zeiss Myolens TM spectacle lens, orthokeratology contact lenses and a multifocal soft contact lens known as Coopervision MiSight TM


Studies show that orthokeratology contact lenses and MiSight TM lenses have the highest ability to reduce the rate of myopia out of the non-pharmaceutical options. 


Myopia control is an extremely important aspect of eye care in that patients who are very short sighted not only are more reliant on their visual devices for correction, but also carry increased risks of retinal detachment, glaucoma and myopic retinal degeneration. All of these conditions are potentially blinding. 


We have extensive experience in fitting orthokeratology contact lenses and are one of the few practices in Australia approved to fit Coopervision MiSight TM contact lenses for children and adults.
