Myopia Control In Children
What is Myopia?
Myopia is a common refractive error which near objects appear clear, but objects farther away look blurry. Typically, myopia will develop through childhood and adolescence.

What causes myopia in children?

 

Myopia occurs when the cornea is too curved or the eyeball's axis is too long, or both, causing light to focus in front of the retina instead of on the retina as usual. Factors that can increase your risk of nearsightedness include:

  • Genetics: If one parent is nearsighted, the risk of their child developing myopia increases. The risk is even higher if both parents are myopia.
  • Visual habitsSome studies have shown that constant working, studying at close distance, or lack of outdoor activities can increase the risk of developing myopia.
Why myopia control is important?

Progression of myopia in children's eyes is an inevitable process, but there are many myopia control methods. Slowing the progression of myopia is a factor that should be a concern for parents because myopia rapidly progresses can bring many inconveniences and risks to children's eyes:

  • Children will have to change glasses regularly to achieve maximum vision.
  • High myopia increases the risk of other serious eye problems such as strabismus, amblyopia, retinal degeneration, cataracts, macular degeneration, and retinal detachment.
  • Severe myopia may make children limited in choosing surgical methods to treat refractive errors when they reach adulthood.

Types of Myopia Control

1. Orthokeratology (Ortho-K)

Orthokeratology is the temporary reduction of myopia achieved by the programmed application of contact lenses to reshape the cornea at night at bedtime (average 6-8 hours per night) and take it off when you wake up the next morning. Children will get clear vision during the day without glasses or contact lenses. Ortho-K is highly recommended by ophthalmologists for its effectiveness in slowing the progression of myopia. 

When using Ortho-K lenses, parents need to guide their children on how to put on and remove the lenses and how to keep them clean to ensure safety and maximum effectiveness.

2. Atropine eye drops (0.01%)

Atropine 0.01% eye drops are prescribed by doctors for children with myopia between the ages of 6 and 15, with at least 0.5 diopters of myopia and rapid progression of myopia. Research shows that myopia in children from 6-12 years old slows down by 50% over 2 years of treatment. Atropine 0.01% is a prescription eye drop, only used when prescribed by a doctor with the dosage, time, and method of use according to specific instructions. Therefore, parents should not give Atropine 0.01% to children without consultation from a doctor.

Children are recommended to use Atropine 0.01% for a long time (at least 2 years), use it properly, and visit for follow-up as scheduled to achieve the best result of myopia control. When using Atropine 0.01%, the child may have slightly blurred vision at close range in the morning due to pupil dilation, but this side effect will disappear about 1-2 hours after waking up.

3. Multifocal eyeglasses
 
Multifocal lenses contain multiple lens powers to provide vision at all distances - close up, intermediate, and distance. Therefore, reduce the accommodative response in the eye when changing distances - near - intermediate or sharpen the peripheral blur to reduce lens-induced axial myopia elongation. Through this mechanism, multifocal lenses help slow down themyopia progression in children. Children will need a certain amount of time to get used to glasses.
 

4. Wearing the correct glasses

Contrary to the concept of wearing glasses with lower power can help to reduce myopia, the fact is that wearing the right glasses is a good solution for the eyes. However, this does not guarantee good distance vision for children, forcing the eyes to work harder. Therefore, according to ophthalmologists, wearing glasses with the correct number will bring the maximum effect in terms of improving vision, and also help to control myopia progression. This is an easy-to-use solution, but mono-focal lenses can cause diffraction, especially with high myopia, causing images at the edges to be less clear.

5. Visual habits
 
  • Less time focusing on near objects and using digital devices, follow the 20:20:20 rule (every 20 minutes spent using a screen; try to look away at something that is 20 feet away for a total of 20 seconds).
  • The study table should be located near the window to receive natural light. Seat heights and table heights are suitable for the student's age. Screens or reading material should be directly in front of them, about an arm's length away, and at eye level to avoid looking down too much
  • Spending at least 2 hours a day outdoors will help enhance distance vision. Moreover, seeing in natural light conditions not only inhibits the development of myopia, but also prevents myopia in children.
When to stop myopia control treatments?
-    Age 8-13: This is the age when it is necessary to control the progression of myopia most closely.
-    Children with myopia are always at risk of continuous myopia progression until adulthood (18 years old). Therefore, in many cases, if myopia is still at risk of progression, it is possible that doctor will prescribe myopia control treatment until adulthood.
