• Do you want to correct your vision and be free of glasses or contact lenses during all waking hours?
  • Do you want a safe, non-invasive alternative to laser eye surgery?
  • Do you want to ride your bicycle, swim or surf with absolute freedom?
  • Are dry, uncomfortable contact lenses affecting your life?

Orthokeratology may be a solution for you. Also referred to as Ortho-K, Corneal Refractive Therapy (CRT) or Overnight Vision Correction, Orthokeratology is a unique technology that utilises custom-fitted, oxygen-permeable rigid contact lenses to improve vision through the reshaping of the cornea while you sleep. This safe, non-invasive and convenient process allows you the freedom to see clearly without daytime vision correction, since the lenses are worn overnight. Ortho-K is suitable for most short-sighted patients, with or without astigmatism, and ideal for sportsmen and women, swimmers, surfers, or those who simply prefer not to wear glasses or contact lenses during the day. Like refractive surgery, Ortho-K gives clear unaided visual acuity; however, it has no surgical risks and is reversible. Browse through this website for more information or call our Sydney Smart Vision Optometry practices to book an Ortho-K consultation.


At Smart Vision Optometry, we use the absolute latest innovative technology available in optometry today for the very best results. Our optometrists have extensive experience in Orthokeratology and are members of the Orthokeratology Society of Oceania (OSO), which is dedicated to promoting research, professional development and networking in the Orthokeratology field since 1984. As Behavioural Optometrists, we take a holistic approach in the treatment of vision while involving our patients as active participants in the prevention of vision difficulties and the maintenance of maximum eye health and visual fitness. Our ultimate goal is to find the answers to our patients’ individual vision challenges, ensuring they see the world clearly and with maximum efficiency.




Master of Optometry, Behavioural Optometrist & Orthokeratologist

Gary has been practicing optometry for over 25 years. After graduating as a Bachelor of Optometry at UNSW, he worked with experienced optometrists throughout Sydney. He then decided to open up his own practice in the Central Coast, later Wahroonga and then Mosman. In 2012, he created the Smart Vision Optometry Group and associated with Thompson, Larter & Associates Behavioural Optometrists, opening a practice in Bondi Beach two years later. Gary studied a Post Graduate Certificate of Behavioural Optometry, in which he achieved a high distinction, and a Post Graduate Certificate of Ocular Therapy, having recently completed a Master’s Degree in Optometry. He is a member of both the Australasian College of Behavioural Optometrists and Optometry Australia. Gary has a special interest in children’s vision, sports vision and visual performance. He has been an Ortho-K wearer for over two years and no longer needs glasses or contact lenses for vision correction.



Behavioural Optometrist and Orthokeratologist

Jacquie graduated from the UNSW with a Bachelor of Optometry (honours) in 1989 and has completed the Behavioural component of her Master’s Degree in Optometry. She has worked in independent private practices in Sydney’s Eastern Suburbs and the North Shore as well as in public research facilities. She is highly experienced in general practice with a particular emphasis on contact lenses and management of diabetic retinopathy and glaucoma. In addition, Jacquie has a personal and professional interest in children’s development. She is passionate about providing solutions to help them reach their learning potential. Jacquie is a member of Optometry Australia and the Australasian College of Behavioural Optometrists, having joined the Smart Vision Group in 2013. She has been wearing Ortho-K lenses since 2013 and is happy to recommend this treatment to all suitable patients.


Did you know there is a non-surgical alternative to daytime contact lenses and glasses? Ortho-K lenses are worn while you sleep and are removed in the morning. They have a unique design, which generates pressure in the thin layer of tears under the contact lens. It’s like braces for your teeth. The cornea is highly elastic and will return to its original shape if the lenses are not worn on a regular basis. For this reason, Ortho-K lenses are usually worn every night to maintain the re-shaping effect once the desired cornea shape has been achieved. After you remove the lenses in the morning, the result is clear vision the whole day, without the need of glasses or contact lenses. Ortho-K has no permanent ocular change, giving you ultimate control and flexibility of your vision correction without the risks involved in laser eye surgery.


Is Ortho-K a new technique?
Ortho-K has been around for over 50 years, but the results used to be very hit-and-miss due to a lack of understanding of the principles involved. With the development of new contact lens materials, allowing safe overnight wear, improved accuracy of lens manufacture and sophisticated corneal mapping instrumentation, Ortho-K has progressed to a scientific discipline with predictable and measureable results.
Can any optometrist provide Ortho-K?
As Ortho-K requires specialised equipment and training, most optometrists do not offer this treatment. Our optometrists are members of the Orthokeratology Society of Oceania (OSO) and have the expertise to assess, monitor and control the corneal reshaping process in order to provide precise vision correction.
Is Ortho-K suitable for everyone?

Early Ortho-K lenses were limited to low to moderate myopia with minimal astigmatism. However, recent advances are allowing us to correct prescriptions that could never be done before – and the technology is improving at an incredible pace. We have corrected high myopia (up to -12.00), astigmatism, hyperopia and presbyopia using Ortho-K lenses. A thorough examination by our orthokeratologists is required to determine your suitability for Ortho-K, which also take into consideration factors such as corneal shape and corneal thickness.

How are Ortho-K lenses prescribed?
Firstly, a comprehensive vision and eye health examination is performed, as well as a very precise map of your corneal topography to design your Ortho-K lenses. After the initial assessment for suitability, customised lenses are manufactured and your first night’s wear is undertaken, with an optometric follow up appointment the following morning to assess the initial results. The corneal reshaping lenses may need to be adjusted and modified in the initial 3-month fitting process. Therefore, progress is closely monitored, sometimes requiring the patient to return the next morning again or up to one to two weeks later for reassessment. Most of our patients see more clearly in as little as one night of wearing Ortho-K retainer lenses. Vision is normally good during all waking hours within the first week. Our patients are also checked regularly for lens effectiveness and eye health.
Can Ortho-K halt the further progression of myopia in children?
Researches have shown that children and adolescents who have had Ortho-K have a similar amount of myopia when they cease the treatment to when they started it. Comparably, this is different to the regular progression of short-sightedness, which tends to get worse as they get older. Significant myopia progression can be prevented by performing Ortho-K during the ages when the fastest progression is occurring.
What are the advantages of Orthokeratology?
  • Freedom from glasses and contact lenses throughout all waking hours.
  • Discomfort normally associated with contact lenses, hard or soft, is minimised or eliminated through overnight use.
  • Ortho-K lenses are only worn at night, greatly reducing the risk of lenses being lost or damaged.
  • It is a non-surgical procedure that does not permanently alter the cornea.
  • It is reversible, with vision returning to normal 72 hours after discontinuing treatment.
  • It is a very safe process, with risks comparable to those associated with regular contact lens wear.
  • It allows active children, teenagers and adults to engage in a variety of activities and sports free from the discomfort and inconvenience of glasses or contact lenses.
  • Ortho-K lenses may reduce the progression of myopia in children and teenagers.
Are there any risks or side effects?
As with all contact lens wear, you must be careful to follow all instructions regarding the care and storage of lenses to ensure your eyes remain healthy. If you properly care for your eyes as instructed, the risk of adverse effects or eye infection are very low. In our practices we have not had one case of adverse reactions because the right clinical care is maintained. Parents are recommended to supervise young children in the insertion, removal and care of their lenses.
Does Ortho-K hurt?
Some people have comfort issues when attempting to wear rigid gas permeable contact lenses during the day. But since Ortho-K lenses are worn during sleep, comfort and lens awareness are generally not a problem.
Do I need to wear Ortho-K lenses forever?
You can stop at any time and just revert back to how you were. Whilst you want to be free of glasses or contact lenses during the day for distance vision, you will need to wear the lenses every night. At present, this is not a permanent “fix”, but technology is changing all the time.
Is Ortho-K expensive?

The Ortho-K fitting process is significantly more complex than a regular contact lens fitting. It requires a series of practice visits and potentially multiple pairs of lenses. Therefore, the initial cost is slightly higher than a year’s supply of regular contact lenses, but less expensive than laser surgery. It includes a comprehensive vision test, a retinal exam, corneal topography, corneal lenses design and fitting, all of the professional visits and the final set of lenses needed to achieve optimal vision for up to 12 months, after which period the lenses must be replaced. An initial assessment to determine suitability ranges from $150 of which Medicare may provide a partial rebate. 

As Behavioural Optometrists, we take a holistic approach in the treatment of vision while involving our patients as active participants in the prevention of vision difficulties and the maintenance of maximum eye health and visual fitness. Our ultimate goal is to find the answers to our patients’ individual vision challenges, ensuring they see the world clearly and with maximum efficiency. It is, therefore, quite likely that a functional vision skills assessment would also be performed to provide the best solution for your visual needs. This cost may vary from a minimum of $85.00.

If you require more information about the costs involved in the Ortho-K treatment, please request our Information Pack below.

Is Ortho-K claimable under health insurance?
Medicare does not cover contact lens consultations for patients with less than -5.00 dioptres of myopia. Private health funds may have a distinct Ortho-K lens rebate or may simply pay the regular RGP refund.
Who can benefit from Ortho-K?

Anyone who wants to be free of glasses and contact lenses during waking hours. Ortho-K is also ideal for sportspeople, surfers, swimmers, people working in dusty environments and in occupations where glasses or contact lenses are a disadvantage (dancers, fashion models, policemen, firemen, etc.)
