The myopia control clinic Western Australians rely on, Abernethy Owens Orthok service helps people with short sightedness/myopia to see clearly in the daytime without the use of prescription.
Orthokeratology (Orthok) is the use of contact lenses overnight to remould the shape of the eye to reduce or correct refractive errors of the eye. In some ways it is similar to the use of braces by an orthodontist to straighten crooked teeth. The main difference is that if a tooth is corrected for some months it will stay in the new position. The cornea is highly elastic, however, and always returns to its original shape. For this reason, the lenses are worn typically every night as a retainer. Established wearers can often miss a night without any loss of optimal treatment.
The original purpose of Orthok was to be free of both contact lenses and spectacles for all waking hours. This is ideal for sportspeople, swimmers, dry eye sufferers, or those who work in dusty or dirty environments and may be appealing to other spectacle or contact lens wearers who wish to be free of their optical appliances.
Long term studies have now demonstrated that Orthok can significantly slow the progression of myopia (short-sightedness) in children. This has the added advantage of reducing the risks later in life associated with higher levels of myopia, such as retinal detachment.

What are the disadvantages?
Orthokeratology contact lenses are a great non-surgical solution for people of all ages who experience the struggles of myopia/short sightedness. Known as a gentle approach to shaping the cornea, Orthok contact lenses are an ideal option for short-sighted children of most ages, especially for those who are too young to be treated by invasive vision correction procedures like laser surgery.
First an initial eye examination appointment is required to assess the general condition and health of the eyes, take measurements and discuss the likely effectivity of the procedure in your own case
After taking detailed corneal measurements your Orthokeratologist will then design your custom retainer lenses. Very rarely an overnight trial with a generic lens may be needed to assess the corneas response and individual tolerability, however this can often be misleading as the custom moulds are much more comfortable.
Once the lenses are manufactured an appointment is scheduled to teach you how to insert, remove and care for the lenses. Overnight wear is commenced and a follow-up visit is scheduled in the morning after a few nights of wear. Another morning appointment is scheduled following 2 weeks of wear. At this point full correction is expected to be achieved. A further check is then scheduled late in the day after a month to ensure the correction is lasting a full day. The lens design may be adjusted accordingly at any of these visits if optimal correction has not been achieved.
If you have private health insurance, your optical benefits may cover part of the lens cost. The amount covered depends on your optical cover policy.
