There’s a common clinical belief that orthokeratology doesn’t work as well in lower myopes for myopia control. This is even sometimes included in conference presentations as prescribing advice. Is orthokeratology useful for control of low myopia? Here’s what’s fact and what’s fiction, when considering its efficacy for low vs high myopia, and orthokeratology vs multifocal contact lens myopia control.
This research summary describes the major multifocal contact lens (MFCL) research studies for myopia control, and what we still need to learn. From the first studies only a decade ago, to wearing time, commercially available lenses, the influence of BV, novel designs and more, this comprehensive review will get you all the way up to date on MFCLs.
Soft contact lenses designed to simulate the change in refraction optical pro-file from orthokeratology (OK) fail to slow axial eye elongation or change to refrac-tion over 1-year of wear in children, leading to suggestion that OK’s propensity to slow myopia progression may not be due to changes OK makes to optical profile.
