When it comes to contact lens corrections for young myopes, the impact of orthokeratology (OK) and multifocal soft contact lenses (MFSCL) on binocular vision is pertinent to visual comfort and understanding mechanisms of myopia progression and control.
Changing a myope from spectacle to contact lens wear can alter their binocular vision (BV) function. The myope reading through their spectacles experiences base-in prism at near, as demonstrated in the image above, which moves the image further away and decreases vergence demand.
This article groups common clinical treatments in an effort to explore what we do and don’t know regarding myopia control efficacy. It highlights the need to balance the available evidence with emerging knowledge when discussing options for myopia control with patients and their carers.
Podcast summary: Are progressive addition lenses and bifocals created equal for myopia control? How should we pick which lens type
The session topics covered prevalence, progression and risk factors of myopia, mechanisms such as light exposure and visual pathways, optical and pharmacological methods of myopia control, genetics, clinical trial considerations, myopic eye shape and accommodation and binocularity.
