Orthokeratology

Request Appointment

Orthokeratology - Ortho-K - is Effective for the Treatment of Myopia (Nearsightedness), Hyperopia, and Astigmatism.

Non-Invasive and Non-Surgical

The process of Orthokeratology involves using specialized contact lenses to reshape your cornea. As your cornea changes shape, refractive errors that cause myopia/hyperopia/astigmatism are corrected.

Overnight Treatments Are Effective and Convenient

Patients following our orthokeratology program wear their corrective lenses at night while they are sleeping. Because of this, they are generally not required to wear corrective lenses during the day.

Vision Correction in Just 2-3 Weeks

Your cornea will undergo a period of rapid adaptation once you begin following the treatment program- typically within a few hours or days.

After 2-3 weeks your cornea will have completed its full adaptation. Ongoing treatment will ensure long-lasting vision correction.

Over 90% of Qualified Candidates for Ortho-K See Improvement to 20/40 or Better
When treatment is maintained, over 65% of patients achieve 20/20 eyesight again. The vast majority achieve at least 20/40, which is the minimum necessary for driving without the aid of corrective lenses like glasses or contacts.

Ask us about whether or not Orthokeratology is appropriate to treat your vision impairment. Our Optometrists will be happy to provide you a recommendation based on the current state of your eye health.

Additional Information About Orthokeratology (Ortho-K)

What are the potential side effects of Ortho-K?

Ortho-K is considered very safe. However, like any treatment, there is the small potential of some side effects being experienced by a small percentage of people undergoing Ortho-K treatment.

These include:

  • Ghosting
  • Double vision
  • Contrast problems and/or starbursting

These side effects commonly resolve before the end of the first month of treatment. As well, the above risks can be mitigated effectively via a comprehensive fitting measurement/application process.

What can Orthokeratology effectively treat?

Orthokeratology is effective up to -6.00 diopters (for myopia) and a maximum of 1.75 diopters (astigmatism).

Orthokeratology is also known as Ortho-K and Corneal Refractive Therapy (CRT). The oxygen permeable contact lenses used in Ortho-K treatment gradually flatten the cornea, improving vision.

Orthokeratology is completely reversible- simply discontinue treatment and your eyes will return to their pre-treatment state over the span of a couple of weeks.
