This 2019 study evaluated 3-year MiSight efficacy in a randomised clinical trial conducted across four different sites, in Singapore, Canada, Portugal and the UK to yield promising findings, with efficacy results comparable to previous studies, and overall high satisfaction reported by subjects. Eye Care Practitioners can utilise these results to confidently educate patients and their families on the efficacy of this treatment option.
The authors conducted a 2-year double blinded, randomised control trial to evaluate the efficacy of novel contact lens designs for myopia control. Lens I and II induced myopic defocus across a large portion of the retina, while Lens III and IV featured an extended depth of focus incorporating higher order aberrations to modulate retinal image quality. This technology is utilised in the Mark’Ennovy Mylo the and Seed 1-Day Pure EDOF lens.
Pathologic myopia is one of the major causes of blindness worldwide. Degenerative changes associated with high myopia, including posterior staphyloma formation and scleral thinning, are caused by the progressive elongation of globe axial length and stretching of the sclera, choroid and retina. The aim of this meta-analysis was to investigate and quantitatively define the efficacy of PSR in controlling axial elongation and refraction progression.
There is general widespread accepted belief that increasing time spent outdoors can be protective against progression of myopia. Xiong et al set out to better understand the research by performing a meta-analysis of 51 clinical trials and longitudinal studies that investigated the relationship between time spent outdoors and the risk of either developing myopia, progression of existing myopia or a myopic shift in refractive error.
Being able to assess myopia progression in a similar way to height and weight using growth curves is beneficial for both practitioners and patients as it provides a comparison against a calculated average, helping to predict future high myopes and track progression and control outcomes. How to growth charts from European and Asian studies compare? We explore the comparisons, advantages and disadvantages of using growth charts for axial length in myopia.
This landmark paper examines the theory underlying the reporting of myopia control efficacy and the sequelae of such investigation. The authors propose an alternate method of reporting efficacy; Cumulative Absolute Reduction in Axial Elongation (CARE), which conveys the benefit that a child receiving a specified treatment might expect, independent of age, progression rate, refractive error and ethnicity over a stated time period.
This paper investigates the relationship between myopia, the objective measure of smartphone data usage and self reported duration of smartphone use in school children and university students with a secondary aim to assess whether study outcomes changed with age.
This retrospective cohort study established the prevalence of adverse events in children wearing soft contact lenses, and found them comparable to established rates among adults wearing soft CLs.
The authors evaluated the Rotterdam, The Netherlands Generation R dataset to establish the risk factors associated with change to axial eye length and incidence of myopia in children from age 6 to 9 yrs.
For many children using digital devices is a normal part of their everyday lives and they will use computers and hand-held devices at school and at home. This systematic review collates this published research to illuminate current understanding on the association between the time children spend on digital devices and incidence, prevalence or progression of myopia.
