Myopia Control


Practitioners who fit orthokeratology lenses sometimes comment that the normal increase or progression of myopia in children is slowed when these lenses are worn. Although these anecdotal reports are encouraging, at present there is no scientific proof of myopia control with orthokeratology lens wear.

A recent study from Hong Kong suggested that myopia progression may be slowed by up to 50% during overnight orthokeratology. However, the authors of the study found that there was no way to predict the effect for individual children. There were also a number of scientific flaws in the study design, and because of these limitations the results of this pilot study are not definitive.

Further research is thus required to determine whether orthokeratology lenses can reduce the rate of progression of childhood myopia.
