Repeated low-level red-light (RLRL) therapy has emerged as a potential nonpharmacologic option for pediatric myopia control, but long-term real-world data remain limited. To address this gap, a study evaluated the safety and efficacy of RLRL therapy over up to three years in children and adolescents with myopia in routine clinical practice. The study included 362 myopic patients aged 7 to 18 years who received RLRL therapy twice daily.
Among those treated for at least three years, 72.5% achieved satisfactory myopia control, defined as annual axial elongation of 0.10 mm or less, with a mean axial length progression of just 0.06 mm per year. Best-corrected visual acuity remained stable across all groups, and no treatment duration-dependent changes were observed on full-field electroretinography. Minimal, reversible OCT changes were noted in four eyes, without any impact on visual…
