  • What are Ortho-K lenses?

    Ortho-K lenses are a brand of rigid, oxygen-permeable lenses. This custom-designed lens is to be worn overnight to gently reshape your patients’ corneas as they sleep. This reshaping is designed to provide clear daytime vision, free of glasses and contact lenses.They are often called corneal reshaping lenses or corneal refractive therapy (CRT). Evidence shows that children who wear these specific lenses end up with less Myopia as adults because the lenses control eye elongation which is a central factor associated with the progression of Myopia.

    Ortho-K is a long-term treatment with lenses that should be worn nightly. The benefit is that since they do their work at night, they do not need to be worn during the day. They also can completely reverse Myopia.
  • Are Ortho-k lenses safe for my child?
    This advanced treatment is safe, effective, FDA-approved, and proven on over 2 million eyes around the world.
  • What is the success rate of designs using Ortho-K options?
    With a documented study that shows a 95.5% fit success and 80%+ initial lens success rate1, your first Ortho-K lens is very likely to be the best lens.
  • What is unique about Ortho-K lenses for myopia management?
    There are unique advantages of Ortho-K proprietary lens design by various companies:
    • Dual alignment curves gently align the peripheral cornea, offering better centration for a closer, comfortable fit
    • Empirical and intuitive design offers control over the size of the treatment zone • Optimal peripheral defocus with the treatment zone mostly inside the pupil
  • How many diopters of myopia can be treated with Ortho-K lenses?

    Orth0-K lenses can be worn by anyone regardless of age, and all patients can experience the benefit of clear sight during the day. However, studies have shown that myopia generally manifests between the ages of 8-12, so it is recommended that young patients are fit between those ages for the best management of their myopia. Starting a myopia management program at any time during the growth years (8-23 years of age) can still have great benefits.9-22
  • Do these lenses work on patients with astigmatism?
    Corneal astigmatism often will cause a lens to decenter in the closed eye. Ortho-K lenses are designed and approved to fit patients with up to -1.50D corneal cylinder without any additional design modification. Ortho-K Toric lenses designs can also be ordered for those patients whose topography shows a limbus to limbus astigmatic “bow tie” pattern and/or measures over 30 microns of sagittal height difference (vertical to horizontal) at the 8mm chord where the lens settles onto the corneal surface.
  • Orthokeratology—is it reversible?

    Orthokeratology is a form of reversible, refractive correction involving the overnight use of gas-permeable contact lenses to reshape the contour of the cornea while you sleep. These oxygen-intense, “breathable” lenses work to temporarily reverse the effects of Myopia during the night so the wearer can experience clear vision the following day—without the use of glasses or contacts. Ortho-K is used primarily to slow the progression of mild Myopia in adults and children, although it can aid in the temporary correction of low-degree astigmatism, hyperopia, and presbyopia as well.

  • What are the advantages of Ortho-K over contact lenses ?

    For those with mild or moderate Myopia, Ortho-K is a great option, especially for sports-related activities or when working in environments containing debris or dust. Ortho-K can also be an effective pre-LASIK treatment that can temporarily stall the need for corrective eye surgery. In addition, the fast, painless and safe process makes Ortho-k a practical solution for children who have Myopia.

  • The Orthokeratology Process

    Orthokeratology involves a three-step process:
    1) the initial examination, where your optometrist or ophthalmologist will use a Topograph to determine the refraction error of the cornea
    2) the fitting, which may happen on the same day, where your eye care professional will select a series of up to three strengths of custom Ortho-K prescription contacts.
    3) the one-to-two-week treatment phase where candidates use their prescription contacts while sleeping for at least six to eight consecutive hours each night.

    Candidates will wear disposable soft lenses or glasses throughout the day during the correction phase. On completion of the treatment, only the prescribed overnight contacts need to be worn. Occasionally, candidates experience mild glaring and haloes around bright light. Remember, there is always the risk of infection without proper eye and lens care, so practice good hygiene and schedule routine follow-up eye appointments!

  • How Costly Is Ortho-K?

    Unfortunately, most insurances do not cover the total cost of Ortho-K. Additionally, costs will vary depending on your eye doctor and your unique prescription. In general, Myopia Control lenses and treatment can cost as much as $2500-$3000.

Taking care of eyesight. Wearers should:

  • Spend more time outdoors, minimum 2 hours a day.
  • Take breaks from long intensive screen time or near-work.
  • Take note of ergonomics, such as proper lighting, posture, keeping the recommended working distance are very important to keep your eyes healthy while doing the near-work.
  • Get regular eye check-ups to ensure that myopia or other vision problems are detected and treated early, reducing the worsening of vision, myopia progression and potential complications of high myopia.
