Milestone: 3-year real-world evidence for RLRL in myopia control!

A groundbreaking new multicentre real-world cohort study published in The British Journal of Opthalmology has evaluated the long-term efficacy and safety of repeated low-level red-light (RLRL) treatment in myopic children and adolescents for periods of up to and over 3 years. Importantly, this study included ffERG as a more sensitive marker of retinal function. 

Key takeaways:

-Sustained efficacy for over 3+ years: the satisfactory myopia control rate (annual axial elongation ≤0.10mm) was found to be 72.5% after more than 3 years of RLRL treatment

-Minimal axial growth: For over 3 years of treatment, the mean axial length change was 0.06mm/year

-No significant differences on ffERG across all treatment durations, suggestive that RLRL did not cause measurable retinal function changes 

This is the first publication to provide robust long-term real-world data into the efficacy and safety of RLRL, strengthening the evidence base of RLRL as a longer-term option for managing myopia progression with continued strong efficacy into its third year.
