Orthokeratology (also known as OrthoK or corneal reshaping lenses) is where we use rigid gas-permeable (RGP) contact lenses to alter the shape of your cornea to temporarily reduce or correct your short sight (myopia) and mild levels of astigmatism. In orthokeratology you wear the contact lenses at night so that you do not have to wear them during the day.
The major benefits of orthokeratology are:
- It is a non-surgical alternative for myopia management.
- Orthokeratology appears to be safe with few, if any, complications.
- It is reversible with corneal shape returning to baseline within about 90 days after discontinuing shaping lens wear.
- Both juveniles and adults can benefit from the visual freedom that ortho-k offers.
- Very easy adaptation with large diameter ortho-k shaping lenses and overnight wear.
- Limited or no daytime wear of correction lenses needed once treatment correction is achieved.
Who can have orthokeratology?
The procedure works better for people who are short sighted from -1.00 to -5.50 D, with no more than -1.500 of astigmatism.
If you are interested in having orthokeratology contact us and we can talk you through what is involved, such as testing your eyes, teaching you how to wear the lenses and all the aftercare required.
Can orthokeratology stop me becoming more short sighted?
Studies show that orthokeratology can slow down and in some cases stop you becoming more short sighted.
Can children wear orthokeratology lenses?
If children wish to undergo orthokeratology, it is essential that their parents are involved to make sure that the child looks after the lenses and follows the instructions given to them.
How often should I have check-ups if I have orthokeratology treatment?
It is essential that you have regular check-ups after the lens fit has stabilised. These would ideally be at least every 6 months. These aftercare examinations will include your contact lens practitioner looking at the condition of your contact lenses and lens case.
