DIMS Lenses May Slow Myopia Progression
A nearly decade-long observational follow-up found continued slowing of axial elongation into late adolescence, while refractive outcomes remained less consistent.
Clinical Report: DIMS Lenses May Slow Myopia Progression
Overview
Pediatric patients wearing Defocus Incorporated Multiple Segments (DIMS) lenses showed a significant reduction in axial elongation over nearly 10 years, as reported in a study. The study indicated a sustained biological effect on eye growth, although the impact on refractive error was less consistent.
Background
Myopia is a growing concern in pediatric populations, with potential long-term implications for vision health. DIMS lenses have been studied for their effects on axial elongation, a key factor in myopia progression.

Key Findings
DIMS lenses were associated with a 65% reduction in axial elongation compared to single-vision lenses.
The cumulative axial elongation among continuous DIMS wearers was approximately 76% lower than normative data from untreated Asian children.
The treatment effect on spherical equivalent refraction was not statistically significant in the primary analysis.
The greatest treatment effect was observed in younger patients, particularly those under 18 years.
The study lacked a contemporaneous untreated control group, limiting direct comparisons.
Clinical Implications
Clinicians should consider the findings regarding DIMS lenses in myopia management.
Conclusion
DIMS spectacle lenses may offer sustained control of axial elongation through late adolescence.
Narrative review linked lower vitamin D levels to greater myopia risk and higher omega-3 intake to lower risk, though outdoor exposure may explain the vitamin D association.
