Myopia control



Eye anatomy - myopia and normal vision showing elongated eyeball in myopic eyes with inability to focus


Myopia has doubled in Canada osince the 1990s and the World Health Organization has called myopia a global epidemic. It can cause vision impairment and even blindness. Myopia is on the rise world-wide for a variety of reasons, including increasing near-work demands and decreased time spent outdoors. Genetics also plays a role. We estimate that one-in-four parents has a child with myopia.


What is myopia?


Many young people have the unpleasant experience of having their eye-glasses prescription go up every time they go to the eye doctor - this process is sometimes very rapid. This is called myopia progression. Myopia is commonly called nearsightedness. Myopia causes the eyeball to get longer, as shown in the image above. Eye doctors measure this enlogation by measuring the axial length of the eye. A the eye ball gets abnormally longer and longer, serious eye diseases may develop.


Patients with myopia are at risk of serious eye diseases


High myopia puts a patient at risk of serious eye diseases that may result in permanent vision loss, including increased risk of peripheral retinal degeneration, retinal detachments, myopic maculopathy, choroidal neovascular membrane and glaucoma.


Are glasses enough for myopia treatment?


Glasses are not enough for myopia treatment. They will allow the patient to see clearly for a time but then the myopia will get worse and new glasses with a more powerful prescription are needed. Therefore, any treatment that can slow or stop the progression of myopia is welcome. Fortunately new treatments for myopia progression based on scientific evidence are available and are effective. Dr. Randahwa has a large myopia control practice and has been succesfull in slowing and stopping myopia.


What are my options for myopia control?
