Two year clinical study outcomes for the Defocus Incorporated Multiple Segments (DIMS) spectacle lens

By Clare Maher | April 27, 2021 | 0 Comments

This study reports two year results from a randomized clinical trial examining Defocus Incorporated Multiple Segments (DIMS) spectacle lenses for myopia control. The findings showed around 50% refractive and 60% axial length efficacy in Hong Kong Chinese children, with an absolute effect of 0.44D lower refraction and 0.34mm less axial elongation in DIMS wearers.

MiSight’s Impact on Binocular and Accommodative Function

By Clare Maher | February 12, 2021 | 0 Comments

The purpose of this 2 year study was to determine the effect of MiSight contact lenses used to control myopia on binocular vision and accommodation in children, as compared with children wearing SV spectacles, with the researches finding no significant differences in binocular and accommodative measures between the study groups.

Determining the Optimal Concentration of Atropine

By Clare Maher | February 5, 2021 | 0 Comments

Despite being used for myopia management for many years, significant controversy exists in both literature and clinical optometric practice regarding the optimal concentration of atropine. The LAMP study sheds light on this mystery by investigating efficacy of 0.05%, 0.025% and 0.01% atropine for slowing myopia progression.

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

By Clare Maher | November 16, 2020 | 0 Comments

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

By Ailsa Lane | April 27, 2021 | 0 Comments

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.
