MYOPIA
CONTROL

Learn about different ways to combat myopia below.

What is myopia?
Myopia is a condition where the structure of the eyeball is longer than average, causing light to be focused in front of the reina (the tissue of the back of the eye), causing blurry distance vision; this is also known as nearsightedness.

Why is myopia a problem?
Myopia can progress yearly, especially in growing children. If myopia continues to progress at a rapid rate, there are vision-threatening risks such as retinal detachment, glaucoma, or earlier inccidence of cataracts. it is criitical for everyone with myopia to have routine dilation or Optomap photos taken.

What can be done to attempt to stop myopia?
Attempting to thwart myopic progression is known as myopia control. There are multiple methods including:
  - Orthokeratology (corneal refractive therapy - CRT)
  - Atropine eye drops
  - Multifocal spectacles or soft contact lenses
ORTHOKERATOLOGY (CORNEAL REFRACTIVE THERAPY (CRT))

What is it?
Rigid contact lenses that are worn during sleeping hours to gently re-shape the cornea or the front of the eye.

What does it do?
We use custom lenses that flatten the cornea allowing for a clearer peripheral image on the retina and that helps to slow the progression of myopia and allow for clear daytime vision without any glasses or contact lenses.

Pros:
​  - Most effective
  - No need for glasses or daytime contact lenses
  - Clear vision for sports
  - Less responsibility for a child
  - Less cost over time
Cons:
  - 6 month initial fitting process with 4-6 visits on

     average
  - May need help with insertion and removal

  - Risks of contact lens wear
  - Initial mild discomfort
  - Higher initial cost

ATROPINE EYE DROPS​​

What is it?
A medical eye drop, Atropine 0.01%, a very low dose used each night before bed.

What does it do?
The eye drops work to relax the focusing muscles of the eye when looking at near objects.

Pros:
​  - No need to worry about a contact lens fitting
  - Less responsibility for a child


Cons:
  - Still need spectacles full-time
  - Low risks of side effects: near vision blur, light sensitivity,               rapid heart rate, and dizziness
 
MULTIFOCAL SPECTACLES 

​​What is it?
Progressive addition lens (PAL) or bifocal spectacles correcting for distance vision, with a gradual change in power towards the bottom of the lens for optimal near vision as well
.

What does it do?
The change in power helps the eyes by relaxing them and helping the eyes to not under-focus or over-focus (aligning eyes better).

Pros:
​  - Spectacles are simple to make

  - No added training


Cons:
  - Least effective on its own for myopia control
  - May need to take extra care when looking down or going 
     down stairs
  - Risk of losing, breaking, scratching, or not wearing
  - Need for separate sports goggles


SOFT MULTIFOCAL  CONTACT LENSES (SMFCL's)​​

​​What is it?
A soft contact lens that is similar to multifocal spectacles, allowing for optimal vision at all distances.

What does it do?
The specific design of the SCLMF helps the eyes by relaxing them and helping the eyes to not under-focus or over-focus (aligning eyes better). Specific to myopia control, it gives a clearer image to the peripheral retina which helps the eye to not elongate or become more nearsighted.


Pros:
​  - Simple fitting process
  - High patient comfort

  - No difficulties when looking down or going downstairs
  - Second highest in effectiveness for myopia control

Cons:
  - May need help with insertion and removal
  - Risks of contact lens wear
​  - Still need back-up glasses
