ClinConnect Summary
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.
