Study Overview

Description: This multicenter, randomized, parallel-group, single-blind clinical trial aimed to assess the efficacy and safety of repeated low-level red-light (RLRL) therapy in controlling myopia progression in children.

Source: PubMed

Summary

Participants: 264 children aged 8–13 years with myopia ranging from -1.00 to -5.00 diopters.

Intervention: The intervention group received RLRL therapy using a desktop device emitting 650 nm wavelength red light at approximately 1600 lux, administered for 3 minutes twice daily, 5 days per week, at home under parental supervision. The control group wore single-vision spectacles (SVS).

Methods: Changes in axial length and spherical equivalent refraction (SER) were measured at baseline, and at 1, 3, 6, and 12 months.

Conclusion

Repeated low-level red-light therapy is a promising alternative treatment for myopia control in children, demonstrating significant efficacy in slowing axial elongation and SER progression, with good user acceptability and no documented functional or structural damage.The Australian National University
