What is orthokeratology?
Orthokeratology, also known as ortho-k, corrects vision using specialised lenses that are worn overnight to gently reshape the cornea while you sleep. This results in clear vision without the need for glasses or contact lenses during the day. Not only is this an innovative method of myopia control but it is also a safe and reversible alternative to laser refractive surgery.
How does orthokeratology work?
Orthokeratology works by using a specially designed contact lens that applies gentle pressure to the cornea, gradually reshaping it. This process is similar to how braces work to realign teeth. By reshaping the cornea, light entering the eye is properly focused on the retina, which can reduce or eliminate the need for glasses or contact lenses during the day.
Is orthokeratology safe?
The use of contact lenses, including ortho-k lenses, carries a risk of eye infection of 1 in every 1000 wearers per year1 in comparison to wearing glasses. Although uncommon, we effectively manage these risks by educating patients on proper hygiene and maintenance practices.

How long does orthokeratology take to work?
You can expect to see improvements within the first 48 hours, with most vision correction occuring within the first two weeks of wearing Ortho-K lenses.
Who is a good candidate for orthokeratology?
Orthokeratology may be a suitable option for individuals with mild to moderate myopia or astigmatism who are seeking a non-surgical method for correcting their vision. It is advisable to adhere to the daily maintenance instructions and get 7-8 hours of sleep per night to achieve optimal results. To ascertain if ortho-k is a viable solution for you, book an appointment with our optometrist.
