OrthoK: night lenses to help you through the day

We’ve a new service which can eliminate the need for glasses or contact lenses during the day. Modern optometry is pretty fabulous! 

Orthokeratology or ‘OrthoK’ doesn’t involve surgery or anything invasive. Specially designed contact lenses work to gently change the shape of the front of your eye while you sleep (a bit like night-time orthodontics) so that you can see clearly, with your natural vision, during the day.

OrthoK is a safe and effective technique, used mainly to correct short–sightedness (myopia), astigmatism and potentially presbyopia (blurred near vision). It’s well worth considering as an alternative to LASIK for anyone who’s not keen on surgery.

This service is currently available at our Sydney Martin Place and Melbourne Fitzroy locations.


How does OrthoK work?

There are various reasons you can’t see clearly: your eye may be too long, too short or the surface of the eye is out of shape – all of which means images don’t focus correctly on the retina at the back of your eye. Normally we fix this by refocusing images using glasses spectacles or contact lenses. But with OrthoK we refocus the images by changing the shape of the front surface of the eye.

To make an OrthoK lens we first map your eye’s surface, using an ultra-precise instrument called a topographer. Then our optometrist uses this information, together with your prescription, to design a customised lens specially for your eye and its unique vision problems.

Topographer maps your eye’s surface

The lenses are made on a computer-assisted high-speed lathe, from materials with high oxygen permeability that allow your eyes to ‘breathe’ while you sleep, to maintain your eye health. The back surface of the lens has several specialised curves that gently shift the tear film under your own lens, and slowly reshape the front surface of your eye as you sleep. The result? After waking and removing your lenses is clear, sharp vision for the rest of the day. It’s pretty clever.

A contour map of the surface of your eye is generated by our topographer. This is used to make your custom contact lenses to wear while you sleep.

Could OrthoK be right for you?

Yes, if you:

  • are unable to wear contact lenses due to allergies and dry eye
  • work in a dusty or dirty environment
  • are an active person who doesn’t want the inconvenience of glasses or contact lenses when participating in sports
  • want freedom from their glasses and/or day contact lenses
  • have mild to moderate myopia (less than -4.00)

OrthoK is worth serious consideration for your child if their myopia (short-sightedness) is getting progressively worse.

What’s involved?

You’ll need a full comprehensive consultation with a Dresden optometrist to assess your suitability for OrthoK. They’ll check your prescription and eye health, conduct corneal topography, and explain how it works and which Dresden OrthoK product would be best for you. This appointment is bulk billed through Medicare (or free if you don’t have Medicare).

If you decide to go ahead, you’ll start an OrthoK Plan, have custom contact lenses arrive 1 week later, then have a series of follow up consultations with our optometrist:

  1. The day after your first night using OrthoK
  2. In two week’s time
  3. In 3 months
  4. In 6 months

Typically, you’ll need to replace your lenses every 12-18 months.

How much does it cost?

Payment for your lenses and the OrthoK program is in two instalments. You’ll pay a non-refundable deposit when your lenses are prescribed and sign a consent form agreeing to commit to your OrthoK program.

You’ll pay the balance when you pick up your lenses. If the program is unsuccessful for you within 80 days, this will be refundable.

If you have private health insurance, you are likely to be able to claim a rebate for your OrthoK lenses.
