Contact Lenses and OrthoK
Orthokeratology or ‘OrthoK’ is the use of contact lenses to reshape the highly elastic cornea (front surface of the eyes). OrthoK reduces levels of myopia and astigmatism through a flattening effect, improving vision during the day.
The lenses are worn at night whilst sleeping and removed in the morning for improved vision during the day. The effect generally lasts for the waking hours (~16hrs) at which point the lenses are inserted again before sleeping. Through the continuation of this routine, seamless clear vision can be maintained. Safety is paramount with any contact lens, and orthokeratology lenses are made from the safest and highest oxygen permeable materials. These materials are specifically chosen to maximise ocular health.
The Orthokeratology patient, once successfully fitted, is then free from wearing spectacles or conventional contact lenses during the day. Consequently, OrthoK improves lifestyle at the same time as vision. It is an ideal solution for those who are sensitive to air conditioning with regular daytime contact lenses and also those who wish to play sport freely.
David has seen great success in utilising OrthoK lenses with patients suffering from myopia as part of his myopia control clinic. OrthoK lenses have proven successful in slowing down or even stopping myopic progression entirely.
