OrthoK for myopia control. Latest theories.
Orthokeratology, also known as Ortho k, is a hard lens worn at night to reshape the cornea, allowing the wearer to see without glasses and contact lenses. In this practice we fit Ortho k mainly for its benefits in slowing myopia progression.
When I first started fitting OK lenses 25 years ago they were mainly being used as an alternative to Lasik, as it provided freedom from glasses and contacts during the day but didn’t require surgery.
Nowadays Ortho k is mainly fit to short sighted (myopic) children, to slow the progression.
Through research, we are greatly improving our understanding of how these lenses control myopia.
Exciting research is investigating what is the optimal treatment zone for myopia control. Current studies are suggesting that a smaller treatment zone may give great myopia control effect, we will watch this space!
Dr Boneham has been designing custom ortho k lenses since 2016, this allows him to incorporate new research, such as treatment zone size, into his lens designs quickly. He can also deal with more difficult fits by changing the curves of the contact lenses.
