About Ortho K

Ortho-K has been practiced for over 50 years and when fitted and worn correctly has a very low rate of complications.

The Ortho K Consultation

Your journey to becoming free from glasses or daytime contact lenses starts with a consultation with one of our optometrists. During this Ortho K appointment we use state of the art Corneal Topography (mapping) technology to measure the exact shape of your cornea.

By mapping the surface of your eye, we can then tailor the Ortho K lens specifically for you, creating a bespoke lens which will gently reshape the cornea with the aim of achieving maximum improvement of your vision.

When your lenses have been produced, we will fit them in the consult room and take more measurements to ensure the perfect fit and refraction has been achieved.

We will show you how to wear your lenses and to care for them so you will be fully confident after your Ortho K consultation with us.

When you are comfortable with inserting, wearing and removing the Ortho K lens on your own, you can wear the lens overnight. The lens will immediately start to reshape your Cornea while you sleep. You will be required to come in the next morning so we can assess the amount of improvement to your vision.

Some people have significantly improved vision at this stage so prepare to be amazed!

A second appointment will be required after 1 week to ensure there is continued improvement in your vision. We will perform further Corneal mapping of your eye in order to assess the quality of improvement and effectiveness of the reshaping.

By this point your vision will have improved significantly.

We will advise you if further consultations are required and when you will need to come in again for further reassessment.

Am I Suitable For Ortho K?

If you are interested in your suitability for ortho K, it is recommended that you call one of our clinics to book in for an Ortho K Assessment, which will be 30-45 minutes. During this assessment, the orthokeratologist will evaluate your glasses prescription, map your cornea (topography) and check that your eyes are healthy and suitable for ortho K.

Although there are exceptions, generally ortho K can work for prescriptions up to -6.00 and astigmatism of up to -3.00. Again, this varies greatly upon the other parameters of the eye and prescription.

Ortho K also can correct lesser degrees of astigmatism, hyperopia and presbyopia. It is important to realise that each patient (and each eye) is different – the type and amount of refractive error that can be effectively managed with Ortho K will be treated on a case-by-case basis.

There is a very high chance you will be a candidate for Ortho K so please don’t hesitate to contact us if you would like clarification or more information, or book an appointment for an initial Orthokeratology consultation to assess your suitability.

How Do I Start Wearing Ortho K Lenses?

Once your orthokeratologist has measured all the necessary parameters, they will order a pair of custom made lenses for you. They will then bring you back for a one hour appointment to assess the fit of the lens on the eye, teach you how to insert and remove the lenses and how to care for them. It is extremely important that you adhere to the guidelines carefully to ensure the safety of your orthokeratology treatment.

At the end of this appointment, you will be allowed to take your lenses home to wear for the night. You will need to return the next morning to assess the treatment.

Following this, you will have appointments scheduled at one week, one month, three months and six months. After this, you will be scheduled for review appointments every 6-12 months to make sure the treatment is stable. This schedule may vary depending on the parameters of your eyes.

Ortho K Contact Lens Insertion

How Does Ortho K Work?

Ortho K lenses are specially designed rigid gas permeable (RGP) contact lenses. This means that they are ‘breathable’ which ensures eye health and comfort is maintained as you wear them overnight.

Ortho K Lenses are designed to be worn at night, while you sleep. Ortho K lenses gently reshape the front surface of your eye (cornea) so you can see clearly the following day once you remove the lenses in the morning.

This is why we say “sleep to see”. With Ortho K you don’t need to wear glasses or daytime contact lenses. All that is required is a good night’s sleep while wearing your lenses and your vision will be clear due to the reshaping of your cornea by the Ortho K Lenses.

If you are myopic (short-sighted), the lenses will gently flatten the central cornea and steepen the peripheral cornea in order to correct the refraction.

If you are hyperopic or presbyopic (long sighted), the lenses work in the the opposite way, with a reverse design to steepen the shape of the central cornea and flatten the periphery.

If you are astigmatic (deviation of spherical curvature), the bespoke, toric Ortho K lenses can be designed to correct vision distortion in vertical and horizontal directions.

Ortho K Reshaping

How Long Does Ortho K Take?

Ortho k lenses improve your vision after first night of wear. During the first week that you wear your lenses you will notice the quality of your vision improving as the quantity of correction increases.

By the first week your vision will have improved significantly (around 50-70% correction) and, in many cases, perfect or near perfect vision is achievable by the first or second week.

How Long Do Ortho K Lenses Last?

It is recommended that you replace your lenses at least every 12-24 months to ensure safety and efficacy of your treatment.

Are There Potential Side Effects?

Overall, Ortho K is very safe. There are potential side effects just like any other procedure. However, side effects such as redness and irritation are often very rare and can often be alleviated by promptly contacting your orthokeratologist. There is a small risk of infection, however, this is mitigated by the careful cleaning and maintenance of your lenses and with regular review appointments.

The most serious problems usually arise from improper lens care, poorly fitted lenses, or lenses made from old lens materials that limit oxygen transmission and compromise corneal physiology. At the Ortho K Group, we only use the latest technology in lens design to ensure your Ortho K lenses are breathable and effective.

Risks associated with Ortho K are similar to risks with contact lens wear, and are not specific to Ortho K. In fact, the rate of complications is actually lower with Ortho K than it is with soft contact lenses.

In order to reduce any side effects, always follow the advice of your optometrist and speak to any of our staff should you have any questions or concerns.

Does Ortho K Hurt?

Many patients who choose to use Ortho K lenses are already contact lens wearers so do not feel significant discomfort with these night-time lenses. Those who have no experience with wearing contact lenses may feel initial discomfort which the body soon adapts too. Just like when you wear a new pair of shoes there can be initial discomfort. However, with time, they become more comfortable.

On your first fitting we will ensure you are very comfortable with the insertion, wearing and removal of the lenses and, if required, we can apply topical anaesthetic eye drops so you won’t feel anything.

Ortho K lenses are worn at night so any discomfort is soon forgotten as you will be asleep.

What If I Want To Stop Ortho K Treatment?

One of the benefits of Ortho K is you can opt to stop your Ortho K treatment at any time. Ortho K is fully reversible. That means, If you stop wearing your lenses, your cornea will return to its natural shape and you can return to wearing glasses or soft contact lenses.

How Much Does Ortho K Cost?

Fitting Ortho K lenses is a more time-consuming process and requires more expertise than fitting regular contact lenses. It requires a series of consultations with the optometrist and potentially multiple sets of lenses.

However, once fitted, Ortho K is less expensive than most daily disposable contact lenses. Ortho K is also significantly cheaper than Laser Eye Surgery or LASIK.

Generally, the costs of Ortho K, including follow-up care associated with fitting the lenses, will vary depending on the type and degree of your refractive error and whether you are choosing Ortho K lenses for long-term myopia control in addition to the temporary correction of existing myopia. Pricing will generally range from $1800 to $2200

Pricing is inclusive of:

  • Corneal mapping
  • Tailoring the lens to your eyes
  • First lens purchase (required to be renewed every 2 years)
  • Follow-up appointments
  • Emergency appointments
  • Initial care products (cleaning solutions).
