Back up corrections, clinical considerations and new designs There’s a little more to think about in the important role spectacle lenses play in myopia management. Even if we prescribe contact lenses, our young myopes are most likely to need a back up spectacle lens option. Children prescribed atropine will need the best spectacle lens prescribed for them to minimise the …
Progressives, bifocals, binocular vision and more Are progressive addition lenses and bifocals created equal for myopia control? When do they work and when do spectacles have minimal efficacy? How should we pick which lens type to prescribe, and what’s on the horizon for our non-contact lens wearing young myopes? We know that single vision spectacle lenses provide no useful efficacy …
While esophoria and myopia have a long-associated link,(1-3) exophoria must also be on our myopia management agenda. The punchline, up front – research has shown that of kids with intermittent exotropia, 50% are myopic by age 10 and 90% are myopic by age 20,(4) and we need to be extra wary if considering fitting a myopic child like this into …
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. Oliver’s story Oliver, age 10, was referred with a history of fast, recent myopia progression. His mother was R&L -7.00 and he was …
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. Looking away from the optical centre of the lens (while keeping the vertex distance constant) also reduces …
This open-access continuing education article I authored was published in Australian professional journal Mivision in December 2018. It describes that while there’s a lot we know about myopia control – the imperative to reduce lifelong risk of vision impairment; that numerous options are available; and that the sooner we start the better – it is imperative for the clinician to …
Podcast summary: Are progressive addition lenses and bifocals created equal for myopia control? How should we pick which lens type to prescribe, and what’s on the horizon for our non-contact lens wearing young myopes? Progressive addition lens (PAL) studies for myopia control show negligible results when single adds are applied to all children, however when applied to children with esophoria …
The sixteenth, biennial International Myopia Conference (IMC) brought together over 350 myopia researchers from more than a dozen countries to drizzly, chilly Birmingham in September 2017, where the latest research was presented in 45 lectures and more than 150 scientific posters over four days. The session topics covered prevalence, progression and risk factors of myopia, mechanisms such as light exposure …
