Condition: Myopia · Sponsor: The Hong Kong Polytechnic University
This research project is a prospective, single-arm, open-label pilot study designed to evaluate the efficacy and safety of focused LED-based repeated low-level red-light (fLED-RLRL) therapy in myopic adults. The primary objective is to assess whether the therapy can increase choroidal thickness and improve choroidal blood flow. The secondary objective is to evaluate the safety and tolerability of red light therapy in adult myopes. The study will enroll 14 myopic adults aged 18 to 50 years, with spherical equivalent refractions ranging from -0.50 to -6.00 diopters. Participants will receive home-based fLED-RLRL therapy (wavelength 650 ± 10 nm, power 0.20 mW) twice daily for 3 minutes per session, 5 days per week, over a total of 28 days, combined with single-vision spectacles. The fLED red-light device employs a standard LED semiconductor chip integrated with a total internal reflection (TIR) lens and microlenses to deliver a precise and concentrated beam, enabling accurate focusing of light energy on the target area. A video tutorial will be provided to guide device usage, and support from the research team will be available throughout the study. Before the treatment, baseline data will be collected from each participant. Baseline and follow-up assessments (days 7, 14, 21, 28) will include comprehensive ophthalmic examinations: visual acuity, intraocular pressure, slit-lamp examination, autorefraction and subjective refraction, optical coherence tomography (OCT), optical co…
