Real-world Registry Study of Red Light Treatment on Myopia Control: a Focus on Non-responders to Conventional Treatments
Sponsor: The Hong Kong Polytechnic University
Summary
This real-world observational registry study aims to assess the effectiveness of Repeated Low-Level Red Light (RLRL) therapy in controlling myopia progression among children aged 8 to 16 who have not responded to conventional treatments like Orthokeratology and atropine eyedrops. The primary focus is to determine if RLRL therapy can limit axial length (AL) elongation to less than 0.1mm per year and spherical equivalent refraction (SER) progression to less than 0.25 diopter per year, while also evaluating safety and visual outcomes.

Repeated Low-Level Red Light (RLRL) therapy
In our study, we do not implement any interventions; rather, we collect follow-up information from patients who, due to insufficient response to traditional myopia control therapies, have transitioned to Repeated Low-Level Red Light (RLRL) therapy. The data gathered will reflect treatment patterns as per the approved indications for RLRL therapy, where subjects may have undergone treatment sessions twice daily, each lasting for 3 minutes with a minimum interval of 4 hours between sessions. Our analysis will focus on the real-world outcomes, specifically evaluating the proportion of participants who have achieved effective myopia control (defined as AL elongation of less than 0.1mm per year or SER progression of less than 0.25 diopter per year) after 12 months of documented RLRL therapy use among the collected data from eligible subjects.
