Since the growing popularity of repeated low-level red light (RLRL) in the past decade for myopia control, many researchers have been trying to understand the mechanism behind this treatment. RLRL therapy results do not match with classical emmetropization theory in that red light, which is a long wavelength, would focus behind the retina and therefore induce […]

Abstract Purpose To investigate the efficacy and safety of repeated low-level red-light(RLRL) therapy combined with orthokeratology(Ortho-k) among the children who, despite undergoing Ortho-k treatment, exhibited an axial elongation of at least 0.50mm over 1 year. Design Multicenter, randomized, parallel-group, single-blind clinical trial (ClinicaTrials.gov,NCT04722874). Participants Eligible children were aged 8-13 years with a cycloplegic spherical equivalent […]

This randomized clinical trial evaluates the efficacy and safety of daily 650-nm low-level red light for myopia treatment among children aged 6 to 12 years in China. Key Points Question What is the effect of daily 650-nm low-level red light (LLRL) on spherical equivalent error (SER) and on axial length (AL)? Findings In this randomized […]

Abstract Purpose: Repeated low-level red-light (RLRL) therapy is an emerging treatment for myopia control. Nevertheless, previous studies are limited by open-label design. Our study aimed to assess the efficacy and safety of RLRL therapy in controlling myopia progression compared to a sham device with only 10% of the original power. Design: Randomized, double-blind, controlled clinical trial. Participants: A […]

Abstract Purpose: To evaluate longitudinal changes in macular choroidal thickness (mCT) in myopic children treated for 1 year with repeated low-level red-light (RLRL) therapy and their predictive value for treatment efficacy on myopia control. Design: A secondary analysis of data from a multicenter, randomized controlled trial (RCT; NCT04073238). Participants: Myopic children aged 8-13 years who participated in the RCT […]

Abstract Purpose: To compare the treatment efficacy between repeated low-level red light (RLRL) therapy and 0.01% atropine eye drops for myopia control. Methods: A single-masked, single-center, randomized controlled trial was conducted on children 7 to 15 years old with cycloplegic spherical equivalent refraction (SER) ≤ -1.00 diopter (D) and astigmatism ≤ 2.50 D. Participants were randomly assigned […]

Abstract Purpose: To assess the efficacy and safety of repeated low-level red-light (RLRL) therapy in myopia control in children. Design: Multicenter, randomized, parallel-group, single-blind clinical trial. Participants: Two hundred sixty-four eligible children 8 to 13 years of age with myopia of cycloplegic spherical equivalent refraction (SER) of -1.00 to -5.00 diopters (D), astigmatism of 2.50 D or less, […]

Abstract Introduction: Axial length (AL) elongation in myopia is considered irreversible. We aimed to systemically report unexpected AL shortening observed in a randomized clinical trial (RCT) after repeated low-level red-light (RLRL) therapy. Methods: This is a post hoc analysis of a multicenter, single-masked RCT. Two hundred sixty-four myopic children aged 8-13 years allocated to RLRL treatment (intervention […]

Abstract Introduction: This study analyzed the effectiveness of 650-nm red-light feeding instruments in the control of myopia. Methods: In this study, 164 school-aged participants diagnosed with myopia in the city of Shenzhen were enrolled in a red-light feeding instrument study. Of these, 41 were enrolled in the mild-to-moderate myopia group that received red-light feeding (RLMM group), 65 […]

Repeated low-level red-light (RLRL), characterized by increased energy supply and cellular metabolism, thus enhancing metabolic repair processes, has gained persistent worldwide attention in recent years as a new novel scientific approach for therapeutic application in myopia. This therapeutic revolution led by RLRL therapy is due to significant advances in bioenergetics and photobiology, for instance, enormous […]
