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.

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, 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. 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.
  3. Unlike laser eye surgery, ortho-K has been shown to slow the progression of myopia (short-sightedness).
  4. 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.
  5. Orthokeratology costs are much more affordable than laser surgery.

Am I suitable for orthokeratology?

We are currently treating myopia (short-sightedness) up to around -5.00 dioptres with orthokeratology, but developments in the future may allow us to treat higher amounts of myopia. 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 motivation, willingness and ability of the child (with parental supervision) to insert, remove & clean the lenses hygienically.

 

Ortho-K is especially good for children & teenagers with progressive myopia – in other words, short-sightedness that is getting worse.
