Efficacy of Repeated Low-level Red-light Therapy in Myopia Control
Recruiting now · Not applicable
Conditions studied: Myopia
In brief
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.
