Myopia (Nearsightedness) Control and Theraphy

What are my child's options for myopia control and therapy?

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. Accelerated Orthokeratology

AOK is a method of reshaping the cornea of the eye without surgery. Oxygen permeable contact lens are worn during sleep which flattens the cornea and reduces myopia (nearsightedness). These lenses are extremely comfortable and safe.

Orthokeratology is currently the most effective method for myopia control.
  • Extremely well tolerated by children.

  • Provides great vision during the day without any need of glasses or contact lenses.

  • Myopia control rates are very high with most patients obtaining from 80 to 100% control.

 

With the advances in AOK lens designs and computer assisted lathe production, we are able to reduce the myopia significantly in a matter of days. Within 7 days most patients achieve 20/20 vision without the use of any glasses or contact lenses during the day. Orthokeratology has been shown to control myopia and prevent further progression. The technique is extremely effective and well tolerated by children.

AOK technology is for you if:

  • You want myopia control.

  • You do water sports.

  • Dry eyes prevent you from wearing daily contact lenses.

  • You cannot have laser refractive surgery.

  • Your prescription is still changing.

  • You want to have a reversible corrective procedure.

ContactLensUpdate - Research in Brief -

Recent studies have shown that AOK controls the increase in the eye’s axial length (the greater the axial length, the higher the myopia) in children. This translates to lower prescriptions once the eye reaches adult maturity.

2. MiyoSmart (Lenses)

MiyoSmart is an award-winning solution designed to slow down the progression of myopia in myopic children and adolescents by up to 59%.

3. MiSight (Soft Contact Lenses)

The lens clinically proved to slow the progression of myopia, decelerating the elongation of the eye and fully correcting refractive error in children 8-12 years old, it is easy to fit and, single-use.

4. Atropine Drops

Low concentration Atropine has recently been found to help slow down the rate of myopia progression and controlling axial elongation. Because of the lower concentration, side effects are lesser than that of full concentration Atropine.

Our optometrists can work with you and your child to determine the concentration of Atropine that will give optimal myopia control and minimal side effects. Lower concentrations of Atropine are not available at a regular pharmacy, but a compounding pharmacy will be able to get the appropriate concentration for your child.
