What is orthokeratology?
correcting vision for adults & kids overnight
Orthokeratology — often called Ortho-K or OK lens for short — is a form of safe, reversible, non-invasive and non-surgical vision correction available to both adults and children.
Ortho-K are special night-time contact lenses worn during sleep to restore clear vision without glasses. You may have heard of them advertised as "Dream Lenses", "Good Night Lenses", "Eye Braces" by some practices.
4 steps to clear vision using Ortho-k lenses
Insert Ortho-K lenses before you sleep.
Remove Ortho-K lenses when you wake up.
Store Ortho-K lenses in solution to clean.
What is ortho-k?
Ortho-K is precise corneal reshaping technology. A good way to imagine orthokeratology is to think "eye braces" — Ortho-K customised rigid contact lenses slowly and gently reshape the front surface of the eye, like how Invisalign and braces shape teeth.
As orthokeratology requires specific instruments, skills and training, not all optometrists can prescribed or fit these lenses. An optometrist with expertise and experience in assessing and fitting Ortho-K lenses is sometimes called an orthokeratologist, analogous to how dental braces are fitted by an orthodontist.
Our experienced orthokeratology practitioner is a member of the American Academy of Orthokeratology & Myopia Control, and participates in continuing professional development and training in Ortho-K to stay at the forefront of this treatment technology.
This clinic is equipped with the latest in digital corneal topography and 3D lens design technologies, all to ensure that our clients can enjoy the best results possible with their Ortho-K vision treatment.
Benefits of ortho-k
Ortho-K lenses can correct mild to moderate degrees of short-sightedness, long-sightedness, and even astigmatism, so that good functional vision can be achieved during the waking hours without the aid of glasses or daytime contact lenses. We routinely fit Ortho-K lenses for prescriptions up to -7.00, and sometimes high prescriptions are possible subject to patient suitability. The highest prescription we have fitted is -10.00 dioptres of myopia.
For adults, Ortho-K gives you the freedom to enjoy clear vision without wearing glasses or daytime contacts. Some of our clients are long-time soft contact lens wearers seeking an alternative as their eyes get too dry with regular contacts. Some have considered laser surgery but wish to try a non-invasive option, or their prescription hasn't stabilise enough yet for permanent surgical correction.
For children and teenagers, Ortho-K lenses have two benefits:
Restoring their vision to be glasses-free for school, sport and all their activities
Slowing down the progression of their short-sightedness (myopia) and helping to prevent their prescription from getting stronger, by reducing abnormal elongation of the eye. That means better vision and better eye health.
Ortho-K is currently the most effective optical treatment for myopia control and commonly regarded as the 'gold standard'. Many clinical studies published over time have demonstrated Ortho-K to be effective in reducing the rate of myopia progression by around 50% in suitable children, and in our clinical experience some children have achieved even better results.
Orthokeratology is one of the treatment options available in our MyopiaControl program.
