The purpose of this study is to determine if repeated low-level red-light therapy can slow myopia progression in Chinese schoolchildren.
Full description
Low level light therapy (LLLT) is an innovative and non-invasive therapeutic treatment for a variety of eye diseases. Its potential mechanisms of improving choroidal metabolic rate and circulation may improve scleral hypoxia, thus slowing down the progression of myopia. The investigator's preliminary case-series study suggested that repeated low-level red-light therapy was effective in slowing myopia progression without any clinically observable side effects. Using a randomized clinical trial design, the purpose of this study is to determine if repeated low-level red-light therapy can slow myopia progression in Chinese schoolchildren. Study subjects will be randomly assigned to either the treatment group (receive repeated low-level red-light therapy) or the control group (wearing ordinary single vision lenses). Axial length and cycloplegic refraction will be monitored over one year (1st month, 3rd month, 6th month and 12th month), after which changes in axial length and refractive errors in the two groups will be compared. An interim analysis will be performed at the 3rd month, at which the data will be reported and presented. Appropriate adjustment of the p-value and decision on the continuation of the study will be made.
