Efficacy of Repeated Low-level Red-light Therapy in Myopia Control
Sponsor: University of California, San Francisco
Summary
Low-level red-light technology provides a new and innovative myopia control approach. This strategy enables relatively high energies of light to be delivered at much shorter durations of exposure to induce the myopia control effect. The efficacy of the low-level red-light technology has been proven in a Chinese population. This trial demonstrated that 3-minutes per session twice a day repeated low-level red-light treatment controlled 87.7% of refraction progression and 76.8% of axial length elongation when the time of compliance to the treatment was 75%. Repeating this RCT in culturally diverse groups will confirm and translate this technology into a solution for myopia control globally.

Low-level Red Light Therapy Device
The treatment device used in this study is a semi-conductor laser product (Eyerising International Pty Ltd, Melbourne, Australia), emitting low-level red-light with a wavelength of 650 ± 10 nm. Based on calculations done by the manufacturer, the device provides light at a power of 2.00 ± 0.50 mW.
