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.

Data Highlights

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.
