Orthokeratology corrects vision overnight during sleep by gently reshaping the cornea. Custom-made contact lenses (or “moulds”) are applied before bed. On awakening, the lenses are removed and you can see clearly all day without glasses or contacts!

Orthokeratology is suitable for all ages but it has a special advantage for children & teenagers with worsening vision, because it actually helps to slow down, or even stop, the progression of myopia (short-sightedness).  No surgery or eye-exercises are required.

Is it new?

Orthokeratology was discovered almost by accident back in the 1960s but the technology then was too limited to provide good results. In recent years, advances in computerised corneal mapping & lens manufacturing technology allowed a huge increase in accuracy and reliability.

Very few optometrists in Newcastle or the Hunter Region of NSW have the equipment and expertise to offer orthokeratology, but it’s available at Custom Eyecare (formerly known as Marketown Optical) in Newcastle’s Darby Street.

How does it work?

Ortho-K uses fluid surface tension to gently reshape the cornea overnight while you sleep to correct your vision.

Ortho-K doesn’t really “press” on the cornea, but instead gentle fluid suction forces “pull” the cornea into the correct shape overnight.

What about laser eye surgery?

Ortho-K is non-surgical, fully reversible, and safe for children. It has several advantages over laser refractive surgery (LASIK).

  1. Once LASIK surgery has cut away the layers of your cornea, it can’t be “undone” if it doesn’t work.
  2. With orthokeratology there is no risk of Post-LASIK Ectasia.
  3. Orthokeratology is more appropriate for people whose vision may change in the future – for example due to normal ageing – because it’s easy to adjust the amount of correction later.
  4. Unlike laser eye surgery, ortho-K has been shown to slow (or even stop) the progression of myopia (short-sightedness).
  5. LASIK eye surgery cuts through corneal nerves, usually causing an increase in dry eye symptoms – but ortho-K is ideal for patients who have problems with dry eyes.
  6. Orthokeratology costs are much more affordable than laser surgery.

Am I suitable for orthokeratology?

We can treat myopia (short-sightedness) up to around -4.50 dioptres with orthokeratology. Higher amounts than this can be partially treated, still with the full myopia-control benefits, along with “top-up” glasses for when the sharpest vision is needed. We can also treat low amounts of astigmatism with orthoK, when it’s present along with myopia.

Happy children using computer

Ortho-K works just as well on children as adults, and so the lower age limit really depends on the maturity, motivation, willingness and ability of the child (with parental supervision) to insert, remove & clean the lenses hygienically. We have successfully treated short-sighted children as young as six years old with orthokeratology.

Ortho-K is especially good for children & teenagers with progressive myopia – in other words, short-sightedness that is getting worse. OrthoK has been shown in scientific studies to significantly slow down the progression of myopia. At Custom EyeCare, we’ve found that it nearly always STOPS vision from getting worse.
