Myopia control efficacy of MiSight 1 day over six years

By Clare Maher | January 22, 2021 | 0 Comments

In this review we explore the 6-year results for MiSight 1 day recently presented at the 2020 American Academy of Optometry meeting. Based on the abstract, children who were older at initial fitting (11-15 years) progressed similarly over 3 years to matched children who were treated for 6 years, indicating that older children could still gain a treatment effect from MiSight 1 day.

MiSight 3-Year Data Analysis

By Clare Maher | January 7, 2021 | 0 Comments

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.

Novel Contact Lens Design for Myopia Control

By Clare Maher | January 5, 2021 | 0 Comments

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.

Posterior Scleral Reinforcement as a means of myopia control

By Clare Maher | December 28, 2020 | 0 Comments

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.

How to assess the efficacy of myopia control treatments

By Clare Maher | December 5, 2020 | 0 Comments

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.

Adverse event rates in paediatric soft contact lens wear

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.

Three year follow up clinical study results of the defocus incorporated multiple segments (DIMS) spectacle lens

Children who had already participated in the two-year clinical trial either continued wearing DIMS or switched from the control SV to DIMS. Comparison to an age-matched historical control group showed a myopia control effect in the third year. 

Change in body height, axial length and refractive status over a four-year period in caucasian children and young adults

By Ailsa Lane | January 15, 2021 | 0 Comments

Can body height compared to axial length be used to predict risk of myopia or high myopia? This longitudinal study examined body height, axial length and refraction – growth mechanisms are likely linked in emmetropes but not in myopes.

How outdoor time influences myopia prevention and control

By Ailsa Lane | December 19, 2020 | 0 Comments

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.

A tale of two studies measuring change to axial length in myopia

By Ailsa Lane | December 12, 2020 | 0 Comments

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.
