Ortho-K & Myopia Control in Markham
Clear daytime vision without glasses—and slow your child's myopia progression
Orthokeratology (ortho-k) uses custom-designed lenses worn overnight to reshape your cornea while you sleep. Wake up to clear vision without glasses or daytime contacts. For children, ortho-k is also one of the most effective treatments to slow nearsightedness progression.
What is Ortho-K?
Ortho-k (orthokeratology) is a non-surgical vision correction method using specially designed rigid gas-permeable contact lenses. You wear them while sleeping, and they gently reshape your cornea overnight. In the morning, you remove the lenses and enjoy clear vision throughout the day—no glasses or contacts needed.
Beyond vision correction, ortho-k is clinically proven to slow myopia progression in children. Studies including the LORIC trial and ROMIO study demonstrate significant efficacy. By starting early, you can reduce your child's risk of developing high myopia and associated eye health complications later in life.

Ortho-K FAQs
What is ortho-k?
Ortho-k (orthokeratology) uses specially designed rigid gas-permeable contact lenses worn overnight to gently reshape the cornea while you sleep. You remove the lenses in the morning and enjoy clear vision throughout the day without glasses or daytime contacts.
How much does ortho-k cost in Markham?
Ortho-k programs typically include the initial fitting, custom lenses, and follow-up visits over the first year. Costs vary based on prescription complexity. Many extended health plans cover a portion of ortho-k lenses. Contact us for a personalized quote after your consultation.
Is ortho-k safe for children?
Yes. Ortho-k is Health Canada approved and has been used safely for decades. It is particularly beneficial for children as it can slow myopia progression significantly, reducing the risk of serious eye conditions later in life. Children as young as 6-8 years old can be fitted for ortho-k.
How does ortho-k slow myopia progression?
Ortho-k lenses reshape the cornea to create a specific optical profile that signals the eye to slow its elongation. Clinical studies including the LORIC and ROMIO trials have demonstrated significant reduction in myopia progression compared to glasses or regular contacts.
How long does it take to see results with ortho-k?
Most patients notice improved vision after the first night, with optimal results within 1-2 weeks of consistent wear. The full myopia control effect develops over several months of regular overnight wear.
Can adults use ortho-k?
Yes. While ortho-k is particularly beneficial for children to slow myopia progression, adults also use it for glasses-free vision during the day—ideal for sports, swimming, dusty work environments, or anyone who dislikes wearing glasses or daytime contacts.
What happens if I stop wearing ortho-k lenses?
Ortho-k effects are temporary and reversible. If you stop wearing the lenses, your cornea gradually returns to its original shape over a few days, and your vision returns to its previous prescription.
Is ortho-k covered by OHIP or insurance?
Ortho-k is not covered by OHIP. However, many extended health insurance plans cover contact lenses, which may include ortho-k. We direct bill most major insurance providers for your convenience.
