Reader Question: I’ve heard about orthokeratology or “ortho-k” lenses that you wear at night to reshape your cornea. Can these help slow down myopia progression, especially in kids?
Ortho-K (orthokeratology) are specially designed contact lenses worn overnight to temporarily reshape the cornea. And yes, they can be very effective at slowing myopia progression in children.
Studies show that they can reduce the rate of eye growth and nearsightedness progression by 50%. The earlier you start ortho-k, the better the results tend to be, making it a great option for younger children.
However, it’s always good to consider the pros and cons before getting started. Here’s a table I made for your consideration:
| Pros | Cons |
| Non-invasive | Requires wearing it overnight |
| Reversible | Meticulous cleaning routine |
| Doesn’t require daytime correction | Initial discomfort |
| Convenient | Higher cost compared to glasses and contacts |
Is Ortho-K Safe?
When fitted and cared for properly, ortho-k lenses are generally safe for long-term use, even for children. However, like other contact lenses, there is a small risk of eye infection.
Fortunately, good hygiene practices and regular eye exams can prevent infections. Maintaining the lenses involves cleaning and disinfecting them daily according to specific instructions. It’s important to follow these guidelines to ensure proper hygiene and avoid any risk of eye infection.
What are the steps to get ortho-k lenses?
First, find an ortho-k practitioner in your area by searching online directories. You can also ask for referrals from your eye doctor, friends, and family.
I recommend choosing someone with considerable experience in fitting ortho-k lenses. But, most importantly, you should choose a practitioner your child feels comfortable with.
The doctor will use special equipment to create a detailed map of your child’s cornea. This map is used to design custom lenses that fit precisely.
Your child will start wearing the lenses overnight, and the eye doctor will monitor their progress closely with regular follow-up visits. It may take a few weeks for the full effect of the lenses to be seen, and adjustments may be needed along the way.
How Much Does Ortho-K Cost?
Ortho-k can be more expensive than traditional glasses or contacts, with the initial cost ranging from $1,000 to $4,000. It depends on the complexity of the prescription.
There may also be ongoing costs for lens replacements and check-ups. Some insurance plans may cover part of the cost, but it’s best to check with your provider.
