Frequently asked questions
How long will it take to reach good vision results?
Results may be noticed in the first few days and best achievable vision will be reached after one to two weeks. However people with higher prescriptions may take longer for vision to stabilise.
Are the results from Ortho-K permanent?
The results are only temporary, once the lenses are no longer worn regularly vision will return to the previous prescription.
Are the lenses easy to insert and remove?
Yes. Insertion and removal techniques are taught in clinic, we will make sure that you are confident with the technique, most people are confident after the teaching and fitting session. Contact lens suction remover is provided.
Do the lenses hurt?
No, the lens will initially cause minor discomfort (the feeling of the lens on your eye) as your eyes adjust.
Are there any risks or can the lenses damage my eyes?
If any type of contact lens is not worn, handled or fitted correctly then damage or infections can occur. During the fit and teach session, we will make sure you are confident with the correct handling techniques.
With proper care and correct techniques, the risk of infection for Ortho-K lenses are less than half compared to over-night wear soft contact lenses.
How is Ortho-K different to soft disposable contact lenses?
Ortho-K lenses are hard contact lenses made from higher oxygen permeable materials. This means different fitting, handling and cleaning procedures.
Do I need to wear the Ortho-K lenses every night?
Yes. The longer and more consistently you wear the Ortho-K lenses, the better and more stable your vision will get.
What happens if I forget to wear them?
There will be a slight deterioration in vision the next day. Putting the lenses in the next night will restore your vision in a few days.
How long does the myopia control effect last?
Myopia control effects last while Ortho-K lenses are worn. Myopia control effect is aimed throughout teenage years and into an individual’s early twenties, by which time vision change should slow down and stabilize.
How is Ortho-K treament different to laser eye surgery?
Laser/Lasik eye surgery is an invasive surgical procedure which physically removes parts of the cornea to reshape it, thus achieving clear vision without glasses or contact lenses. However, like any other surgical procedure, there are risks involved. If you are interested in refractive laser surgery feel free to consult our Optometrists for more information.
Orthokeratology is a non-invasive procedure to reshape the cornea by wearing Ortho-K lenses overnight, thus achieving clear vision during day-time. Ortho-K is reversible by discontinuing wearing the lenses.
What if my drivers licence says I must wear glasses for driving?
Your optometrist can write a letter to explain that you are being treated with a vision correction treatment that eliminates the need for corrective lenses while driving.
How long do I need to wear my lenses for each night?
It is recommended to wear the lenses for 8 hours to achieve best vision results.
