Young adults fit with CooperVision Proclear multifocal contact lenses showed no loss of peripheral vision detection ability compared to single vision contact lenses. The near add was chosen to generate +0.50 or +1.00 of peripheral blur, confirmed by peripheral refraction measurement. This is a positive indication that fitting MFCLs in young wearers doesn’t impact peripheral visual performance.
This study measured central and relative peripheral refraction (RPR) in children aged 6-7 years and 12-13 years at baseline and again one year later. There was no correlation found between central and peripheral refraction in the younger group. In the older group, more hyperopic temporal RPR was correlated with a myopic shift, but only explained 10% of the variance in refraction after 12 months.
It’s known that emmetropizing children undergo axial eye growth of around 0.1mm per year. Is this amount of growth in myopes also ‘physiologic’? In this study, data from six myopia control clinical trials was analyzed to find the axial growth component which did not result in a change in refraction. For myopes, this ‘physiologic’ growth appears to be less than 0.1mm per year, which has implications for judging progression and treatment success.
A country-wide intervention to increase outdoor time in 5-6 year olds resulted in the prevalence of myopia decreasing from 15% in the 2014 cohort (before the intervention) to 8% in 2016 cohort (exposed to the intervention for up to two years) and was stable for three years thereafter. Increasing outdoor time works!
This study utilized data from over 15,000 participants aged 35-74 years and found a five-year cumulative incidence (new onset) of myopic maculopathy in the general population of 3 in 1,000. In 509 eyes with over 6D of myopia, 7% had myopic maculopathy and of these 50% worsened over the study period.
The newest myopia controlling spectacles can both correct and control myopia as effectively as contact lens options. How do Defocus Incorporated Multiple Segments (DIMS) and HIghly Aspherical Lenslet Target (H.A.L.T.) technology spectacle lenses work? Here we investigate and compare their design, presumed mechanism and comparative efficacy for myopia control, based on published research.
This study reports one year results from an ongoing randomized clinical trial examining spectacle lenses with highly aspherical lenslet (HAL) or slightly aspherical lenslet (SAL) technology. The findings showed the HAL lens controlled refractive and axial progression by 60-70% and SAL by 30-40% over the first 12 months.
The NaturalVue Multifocal contact lens by Visioneering Technologies, Inc, is a daily disposable contact lens for myopia control. This blog explores the optical profile, proposed mechanism and research evidence for the NaturalVue, along with its application in practice.
The NaturalVue Multifocal contact lens is a daily disposable which may slow myopia. It is recommended for low astigmatism, as is typical for spherical contact lenses, but its unique optical profile has led practitioners to ask if it can be fit to patients with higher levels of astigmatism. Read this case which highlights the dynamics of a young visual system, using the fitting guide and finding the best solution for a very high myope.
