The Role of Orthokeratology in Myopia Control: A Review. Eye & Contact Lens 2018;44:224–230....description of modern orthokeratology (OrthoK, the use of specially designed rigid gas-permeable (GP) contact lenses worn while sleeping to reshape the cornea and thus the refractive error of the eye)...
Campbell, EJ. Orthokeratology: an update. Optom Vis Perf 2013;1(1):11-18.Orthokeratology treatment involves the use of rigid contact lenses to change the curvature of the cornea, resulting in a movement in refractive error towards plano.
Currently, orthokeratology lenses are designed to have an efect lasting for at least 10-12 hours of functional vision.
...multiple studies have provided strong evidence that orthokeratology can reduce myopic progression. ... The studies show that orthokeratology can reduce myopic progression by 85-93.5% and slow axial elongation.
My daughter and I are getting OrthoK contacts to wear when sleeping, in the expectation that we will be able to see clearly without glasses or contacts when we are awake. The main danger seems to be bacterial infection from not properly taking care of the contacts.
I had never heard of OrthoK until about this year. I was mildly interested in it when I was thinking of myself, though I didn't really look further into it until my daughter was diagnosed with myopia. OrthoK supposedly reduces or stops myopia progression, so the eye doctor recommended it for her. I wasn't going to have my daughter be a guinea pig, so I'm going to wear mine first to show her that it is safe.
It is not cheap, costing over $2,000 for each of us, as it is not covered by insurance. If it stops myopia, then it will be worth it.
Have any of you worn OrthoK contacts or heard of dangerous side effects?
