Myopia (nearsightedness) control and therapy « Welcome to Dr. David Ng and Associates – Trust the health of your eyes to us

For many years the cause of myopia has been a mystery to doctors and researchers.  However recent studies provide evidence that myopia increases when the peripheral retinal images are focused behind the retina (hyperopic defocus). As the child and eye grows there is an attempt of the eye to bring the hyperopic defocus onto the peripheral retina. This results in an increase in axial length which in turn increases the myopia.

There are now two methods we use to eliminate or minimize the hyperopic defocus to help with myopia control.

1. Orthokeratology

Orthokeratology is currently the most effective method for myopia control.

  1. Extremely well tolerated by children.
  2. Provides great vision during the day without any need of glasses or contact lenses.
  3. Myopia control rates are very high with most patients obtaining from 80 to 100% control.

2. MyoVision

This is the world’s first single vision spectacle lens design which uses the Peripheral Vision Management Technology (PVMT).  PVMT minimizes peripheral hyperopic defocus to slow down axial lengthening which results in myopia control.

This technology was launched in Dec 2010 by Zeiss Canada.

With MyoVision myopia control rates of 30% are possible.

The lens is well tolerated by children with almost no adaptation required.

Contact us to learn more about this exciting technology.  Our office is currently the leading dispensers of this treatment in Canada
