Abstract

PURPOSE: To evaluate the efficacy of a myopia control spectacle lens (DIMS) at slowing the progression of myopia in a population of European children in comparison with 0.01% atropine and combined DIMS and atropine.

METHODS: The study was a non-randomised experimenter-masked prospective controlled observational study of individuals aged 6-18 years with progressing myopia but no ocular pathology. Participants were allocated, according to patient/parent choice, to receive 0.01% atropine eyedrops, DIMS (Hoya® MiyoSmart®) spectacles, combined atropine+DIMS or single vision spectacle lenses (control group). The key outcome variables, cycloplegic autorefraction spherical equivalent refraction (SER) and axial length (AL), were measured at baseline and after three, six, and 12 months.

RESULTS: Of the 146 participants (mean age 10.3y ±3.2), 53 received atropine, 30 DIMS spectacles, 31 atropine+DIMS, and 32 single vision control spectacles. Generalized linear mixed model analysis revealed for SER, whilst controlling for age and SER at baseline, at each stage all treatment groups had significantly reduced progression compared with the control group (p<0.016). For AL, whilst controlling for baseline age and AL, at 6 and 12 months all treatment groups had significantly less progression than the control group (p<0.005). For SER only, in pairwise comparisons at 12 months the atropine+DIMS group had significantly reduced progression compared with the DIMS only and Atropine only groups (p<0.001).

CONCLUSION: In a European population, DIMS and atropine are effective at reducing myopia progression and axial elongation in progressing myopia and are most successful at reducing myopia progression when used in combination.
