Myopia Control – Stop your shortsightedness from increasing
Presently, there is no cure for myopia but promising international research, including studies conducted at the University of Auckland, have shown new advancements in reducing myopia progression.
The current theory suggests that myopia progression occurs when light is focussed on the peripheral (side) retina. It is believed that making the light out of focus on the peripheral retina can reduce myopia progression (termed myopic defocus). Speciality contact lenses, using orthokeratology, and optical lenses can achieve this.
Orthokeratology (ortho-k) is FDA approved and has recently been made available in New Zealand and is a safe and reversible treatment for myopia (short sightedness).
You wear a specially designed contact lens while you sleep and your cornea (front surface of the eye) is reshaped allowing light to be focused onto the back of the eye (retina).
Upon waking, you removed the lens and you should have clear vision lasting throughout the day without the need for additional glasses or contact lenses.
Recent research has shown that ortho-k can slow down and even stop the progression of myopia in children and teenagers (myopia control)1,2.
The cornea will go back to its original shape when lens wear is stopped.
MyoVisionTM by Zeiss are optical lenses designed to reduced myopia progression and are worn like ordinary glasses. The principle of these lenses is similar to ortho-k lenses and these lenses have shown to reduce the progression of myopia by up to 30% in certain groups3.
The lenses look like your normal lenses but are specifically designed to allow clear vision through the centre of the lenses but the peripheral area creates myopic defocus.
A recent study investigated the effects of atropine eyedrops in preventing the progession of myopia.
Atropine for the Treatment of Childhood Myopia (ATOM) found that diluted (0.01%) atropine eyedrops used once a day at night could reduce the rate of myopia progression just as effectively as the stronger (0.5% and 0.1%) eyedrops with lower side effects 4.
Atropine is a prescription only medication. It can be prescribed by a therapeutically qualified optometrist or ophthalmologist.
Currently there is no cure for myopia but recent scientific research have opened up an new area to help control the progression the myopia including the use of ortho-k lenses, myopia control optical lenses and atropine eyedrops.
