Awaken to Clarity with Ortho K!
Ortho K (short for Orthokeratology) is the only non-surgical procedure that allows you to see 20/20 without the use of correcting lenses during the day. It is a revolutionary therapy offered at Visique Rose Optometrists, which involves the use of custom crafted molds that gently reshape your cornea while you sleep. Upon waking, your eyes are the correct shape to accurately focus light, enabling you to see clearly without the hassle of contact lenses or glasses during the day!
What is Ortho K?
Ortho K is the only non-surgical procedure that gives you 20/20 vision without the use of correcting lenses (glasses or contacts) during the day.
How does Ortho K work?
Ortho K uses custom crafted molds that gently reshape your cornea while you sleep. Once you wake up your eyes are the right shape, meaning that you can see clearly without contact lenses or glasses during the day.

Who can use it?
Traditionally, Ortho K has been used solely for short-sighted patients. However, recent advancements in technology now mean that this is a safe and effective option for patients of most spectacle prescriptions. Visique Rose Optometrists are the first in New Zealand to be able to offer Ortho K for long-sighted patients, patients with astigmatism, and those struggling with reading vision (vision after 40). Recent research also shows that the use of Ortho K may help to slow down or halt the progression of myopia (short-sightedness) in children.
What does the treatment involve?
The process begins with an initial consultation where our optometrists carry out a full eye examination and take precise measurements of the shape of your corneas using special computerised instrumentation (corneal topography). Assuming your eyes are suitable, you will undertake an overnight trial wearing Ortho-K lenses and the following morning, the effect on your eyes will be assessed.
It may be necessary to have more than one trial to optimise the lens design. With most people, 70% of the reshaping is obtained during the first night and 100% within 14 days. To retain the correct shape, your Ortho-K lenses need to be worn as a retainer at night. If wear is stopped, the cornea gradually returns to its original shape over a couple of weeks. Therefore, unlike surgical options, Ortho-K is completely reversible and no ocular tissue is removed.
Ortho K has long term benefits
Using Ortho K slows down the deterioration of your eyes if you are shortsighted (this is because the lenses reshape your eyes every night). This is good, but also very important if you want to get laser eye surgery in the future.
- What if I have been unsuccessful with contact lenses before?
There is a good chance that you will still be able to succeed with Ortho-K. Many contact lens wearers discontinue wear because of dryness or discomfort. These are usually not an issue with Ortho-K because the lenses are only worn while you sleep. Also, because your eyes are not wearing lenses while awake, they receive more oxygen to help maintain optimum eye health.
- How safe is Ortho-K?
The safety and effectiveness of modern Ortho-K has been demonstrated by independent studies at University Research Departments in Australia and around the World. As with all contact lenses, good hygiene and regular check-ups are important.
- Myopia Control
Until relatively recently there has been no scientifically proven way of reducing the progression (worsening) of myopia (short-sightedness). It has been long understood that genetics and environment play a role, but the mechanism of myopia progression has now had some clarification in research conducted internationally. It has been shown that where the light focuses in the periphery (side) of the retina has a strong influence on the progression of myopia. Studies show that Ortho-k is the best option for myopia control treatment with 50% or greater potential for reduction. For more on myopia control click here.
- How does Ortho-k control Myopia?
When wearing spectacles or traditional contact lenses, the image is clear on the central part of the retina and blurry in the outer parts (or periphery) of the retina. After Ortho-K or corneal moulding, the image is now clear in the periphery of the retina. Creating this situation for a short sighted patient has shown to be a “dimmer” switch for myopia progression. In other words Ortho-k creates a condition that can reduce the progression of myopia.
- How long has it been around for?
George Jessen first announced the concept of “Orthofocus” in 1964. Many manufacturers have coined terms for it such as CRT (Corneal Refractive Therapy), VST (Vision Shaping Therapy), Dreamlens, OK, Emerald, GOV and Orthokeratology. Since then technology has moved this procedure into the 21st century more so in the last 15 years, and this is mainly due to manufacture technique, research into safety and infection rates, and standards of practice in both Australia and New Zealand set about by the Orthokeratology Society for Oceania, this is an concept which is relatively new to New Zealand in many respects but old to the world.
- How does it work?
Orthok works by gently remolding the front surface / window of the eye called the cornea. It does this by using the tears underneath a specially designed mold or lens. The lens itself creates an shape like a dental retainer and it is the sucking forces of the tears which actually do all of the work. The lens itself does not physically press on the eye in any way.
Here’s what some of our patients have to say about OrthoK…
No longer having to juggling three pairs of glasses (safety, sunnys and normal) through out the day has been liberating! –Erin
I used to lose my contacts a lot while in the water, now with Ortho K I can swim, dive and surf with my eyes open without having to worry about losing my lenses. Ortho K has also been fantastic for eliminating the dryness and irritations I used to experience wearing contacts while working on the computer all day, my eyes are now free to breath! –Naomi
I was last able to read a telephone book unaided at the age of about 40. I agreed to a short trial and was amazed after the first night to be able to read relatively fine print without glasses. –Ruth
The trial was very successful, the night time wearing of the lenses was without a single issue and our son now has great vision and the freedom to do what he likes during the day without the issues one has with spectacles or daytime wear contacts. Carole and I are extremely happy with Ortho K and I am so impressed with it that I have been taking every opportunity that I can to tell people of this as a great option for correcting their eyesight, particularly their children. –Langley & Carole
Our family is made up of second and third generation clients of your practice and I would like you to know that it is always a pleasure to deal with any member of your staff. They exude friendliness and professionalism and go out of their way to be helpful. Ortho K has given me the glorious ability to read again without having glasses stashed at numerous points in my everyday life. Thank you I am delighted. –Kind regards, Diane Green.
