Myopia Management

What is Myopia?

Myopia, also known as nearsightedness, is a refractive condition where the distance vision is blurry and the near vision (such as print in a book or a computer screen) is clear. The term nearsighted is a positive one and refers to what the patient can see. There are two main types of myopia one being refractive myopia and the other is axial myopia.


Refractive Myopia

This is caused by the cornea or lens of the eye being too curved or caused by the refractive index of the lens being too high. It results in light being focused too quickly and in front of the retina.


Axial Myopia (most myopia)

This occurs when the eye is too long but the curvature of the lens and cornea is the appropriate shape. This also results in the image being focused in front of the retina but the retina is further back.

Myopia Epidemic

Myopia rates have been increasing around the world in the last few decades. The proportion of the population being nearsighted in 2000 was 23% and this increased to 34% in 2020 with a projected rise to 50% in 2050.

Higher amounts of myopia is a known risk factor for retinal detachment, glaucoma, and macular degeneration. Refractive procedures that change the curvature of the optical components of the eye don’t address potential health complications associated with increasing myopia.

Measuring Progression

Careful measurement of the cornea (refractive myopia) and axial length (how long the eye is) can be used to predict which children are going to experience elongation in the future. If the at risk children can be identified then prevention methods can be used to either slow down the rate of elongation or stop it altogether. The Myah is a commercially available product that can use these measurements to build a risk profile and determine which children would benefit from treatment and to ensure that the treatment is working. This is not covered under the Ontario Health Insurance Plan but is indispensable for myopia progression.

What does this prevention method include?

Corneal Topography including keratoconus screening and pupillometry

Axial Length measurement by Optical Low Coherence Interferometry

Progression reports for analysing treatment efficacy

Myopia Control

Slowing Progression of Nearsightedness

Myopia control is a term used to try and slow the progression of axial elongation of they eye (the eye getting longer). These methods don’t reverse myopia once elongation has occurred but rather prevent it from happening. Different methods target different areas to slow elongation and include medication, specialized spectacle lenses, behavioral changes, and specialized contact lenses. Careful tracking and adjusting treatment as needed are required to minimize myopia progression.
Options for myopia control include :

Outdoor Activity

2 hours a day of outdoor activity helps to prevent myopia but is less effective when a child becomes myopic.

Peripheral Defocus Spectacle Lenses

Specialized lenses that both correct vision in the center of the lens but create a zone of peripheral blur to discourage axial elongation.

defocus contact lens icon
Peripheral Defocus Contact Lenses

These are specially designed soft contacts that a child will put on when they wake up in the morning. They have a central zone of clear vision with a peripheral ring of defocus that slows the rate of myopia progression.

Atropine Therapy

This medication is a drop that is instilled in the eyes once a day before bed. It works on biochemical pathways in the eye itself to slow the progression of eyeball elongation. The medication is not commercially made in the correct concentration and must be compounded to the correct concentration.

These are specialized contact lenses that are worn while the child sleeps. They temporarily reshape the front surface of the eye. This results in vision correction when the child wakes up in the morning and causes some peripheral defocus which can slow myopia progression.
