What is Orthokeratology?

Orthokeratology or Ortho-K is a specialised area of contact lens fitting where a small rigid lens is worn by the patient over night while asleep.

How does it work?

This lens acts as a mould that will very slightly reshape the front surface of the eye, correcting a person’s short-sightedness and astigmatism so that when they get up in the morning and take out the lenses they  will have clear vision during waking hours without the need for glasses or any additional contact lenses. This makes it a very attractive option to people as a non-surgical alternative to laser eye surgery, people who play sports or perform jobs or other activities where glasses are cumbersome and people who have intolerance to conventional soft contact lenses and don’t want to wear glasses. shaping-the-cornea

Unlike laser refractive surgery, the changes to the shape of the eye induced by Ortho-K are completely reversible and if lens wear is discontinued then the eye will gradually return to its original shape within 1-2 weeks. Also unlike laser refractive surgery, adjustments can be made to the lenses later down the track if the person’s prescription changes over time.

Another big benefit of Ortho-K is its proven ability to slow down the progression rate of short sightedness. This makes it a treatment for children or teenagers who are becoming short sighted. Wearing Ortho-K will slow down the rate at which their vision is becoming worse and in some cases completely stop any further changes.
