Orthokeratology At Optometrist Parramatta

Orthokeratology, or Ortho-K is a safe and reversible way to correct your vision overnight, without expensive surgery.

It involves wearing a customised, hard contact lens while you sleep, which gently reshapes your eye to correct your vision – just like a dental retainer.

If you are short-sighted, and have minimal astigmatism.

What Does It Do?

Many common vision problems are a result of the eye being too long or short, or misshapen, which interferes with the eye’s ability to focus light. 

Orthokeratology changes the shape of the cornea, the dome-like window which focuses light onto the retina, which corrects focusing ability. 

These lenses are worn overnight so that your eyes retain their corrected shape throughout the day, like a retainer. 

How Does Orthokeratology Work?

We take precise measurements of the shape of your eyes in order to create customised, rigid contact lenses. These lenses gently reshape the cornea while you sleep. 

When you remove the lenses in the morning, the cornea maintains its moulded shape throughout the day, leaving you with clear vision without the need for glasses or contact lenses!

What Are The Benefits Of Ortho-K?

As these lenses are worn only while asleep, dryness and eye irritation that can occur with soft contact lens wear is minimised.

If that wasn’t enough, Ortho-K has also been found to potentially prevent vision from worsening too quickly. This potential as a preventative technology is very exciting, particularly for younger generations who are generally more affected than their parents due to the huge increase in time spent on digital devices and lack of outdoor activity.

Who Is Suitable For Ortho-K?

Ortho-K  is suitable for all ages, however it is generally most successful in younger patients. It is best for those who are shortsighted and who’s prescription is between the ranges of –0.50 and –5.00, with minimal astigmatism. However, to accurately determine whether or not you will be suitable, a specialised contour map (corneal topography) of the eyes must be taken.

If you are worried about your prescription changing and in particular about your child’s eyesight getting progressively worse, Ortho-Keratology might be just what you’ve been looking for.

We will perform a quick aftercare appointment after the first night’s wear and then one week later. This is to check if any minor adjustments are required and monitor your progress with the lenses.

We find greatest success in those under the age of 30.

It is most effective for people who are short-sighted, and have minimal astigmatism, and especially for children.  

As Ortho-K is an incredibly personalised service, prices vary depending on the prescription and the complexity of the eyes. You can also use your Private Health Insurance to claim on these special lenses.

Some health funds will partially rebate Ortho-K treatment, depending on your cover.

The initial assessment for Ortho-K is rebatable by Medicare, subject to eligibility.

Ortho-K has been successfully used since 1962. Because it is a temporary and reversible treatment, Ortho-K is considered a very safe technology with almost no potential negative side effects.

As with regular contact lenses, there is a small risk of infection if the lenses are not handled in a safe and hygienic manner. This risk is greatly reduced by following the instructions on the appropriate cleaning and handling of Ortho-K lenses which your optometrist will discuss with you.  


The great thing about Ortho-K is that after a bit of adaptation, most people don’t feel the lenses at all! They are a hard contact lens, so when you first insert them you can feel them, but like a retainer, your eyes adapt and as you sleep you will forget they’re even there!

If you do decide to discontinue the treatment, once you stop wearing the contact lenses your eyes will simply revert back to their original, uncorrected state.

The first step is to book a commitment-free Ortho-K Assessment so that we can establish your eligibility and get started today!
