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.
What do you do when your patient doesn’t respond to your orthokeratology (orthoK) treatment and things don’t add up? Here’s a case for you where an optometrist had to become a bit more investigative to determine the cause.
What do you do when your patient doesn’t respond to your low-dose atropine treatment? This case explores the nuances in navigating management when atropine doesn’t work as well as you might expect.
Prototype soft CLs designed to replicate the optical profile induced by OK were found to provide similar whole eye wavefront aberration measurements at distance and near fixation to existing OK lens wearers.
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.
This review covers how well axial length relates to refraction and predicting future myopia, how to measure axial length, its value in orthokeratology and atropine management, how axial length influences a treatment plan and can you practice myopia management without it.
You may be ready to cease treatment, or the patient has done so of their own accord. Then you observe that the rate of myopic progression accelerates again – a myopia rebound effect. When does this happen? Can you avoid it? What should you consider doing in practice?
This research showed that centre near design multifocal CL’s do not appear to reduce visual acuity at near in young accommodating myopes, but result in a slight reduction in visual acuity at distance.
This research investigated orthokeratology lenses designed for a higher peripheral ‘add’ power, and how these influenced corneal hysteresis (rigidity) and higher order aberrations.
Understanding how orthokeratology alters ocular aberrations helps to understand research and potential mechanisms of myopia control. Here we explain more.
