Orthokeratology (Ortho-K) uses specially designed rigid gas-permeable contact lenses worn overnight to gently reshape the cornea. When you wake up and remove the lenses, you can see clearly throughout the day — no glasses, no daytime contacts needed.
Beyond the convenience, Ortho-K is one of the most effective proven methods for slowing myopia progression in children and teens. Studies show Ortho-K can reduce nearsightedness progression by up to 50-60%.
Ortho-K lenses are worn during sleep. They apply gentle, precisely calculated pressure to temporarily flatten the central cornea. This changes how light focuses on the retina and corrects vision for the day. The effect wears off gradually, which is why the lenses are worn each night to maintain clear daytime vision.
Unlike laser surgery, Ortho-K is completely reversible — stop wearing the lenses and your cornea returns to its original shape within a few days.
For parents concerned about their child's worsening eyesight, Ortho-K is one of three clinically proven myopia control treatments available at Avalon Eye Care in Vaughan — alongside soft multifocal contact lenses and atropine eye drops. Learn more about our myopia control services.

Yes — Orthokeratology has been approved by Health Canada and the FDA and has been used safely for over 20 years. Like all contact lens wear, there is a small risk of infection if lenses are not properly cared for. Your optometrist will provide thorough instructions. Children as young as 7-8 can safely wear Ortho-K lenses with parental supervision.
Most patients notice improved vision within 1-2 days of first wearing Ortho-K lenses. Full correction typically takes 1-2 weeks. During this period, glasses or temporary soft lenses may be needed for activities requiring sharp vision.
Ortho-K lenses are not covered by OHIP. However, many private extended health plans include coverage for contact lenses, which may partially offset the cost. Ortho-K is a multi-step process involving an assessment, fitting, and follow-up visits. Contact Avalon Eye Care in Vaughan for current pricing information.
Yes — Ortho-K is one of the most effective methods for myopia control. Clinical studies show Ortho-K slows axial eye growth (and thus prescription increase) by approximately 50% compared to single-vision glasses or contacts. This is important because high myopia in adulthood significantly increases risk of serious eye diseases like retinal detachment and glaucoma.
