Clinical Trial Data on Red Light Therapy for Presbyopia Symptoms

Fan Song's dataset contains results from a randomized, double-masked clinical trial investigating repeated low-level red light therapy for presbyopia. The trial enrolled 66 participants aged 41–62 years and measured outcomes including Computer Vision Syndrome Questionnaire scores and accommodative amplitude over a 1-month period. The data was published on figshare in April 2026 under a CC-BY-4.0 license.

Use Cases

• Analyze the effect of red light therapy on accommodative amplitude based on the primary outcome measure
• Compare changes in Computer Vision Syndrome Questionnaire scores between treatment and sham groups
• Evaluate the impact on vision-related quality of life using the Near Activity Visual Questionnaire scores mentioned in the description
• Investigate subgroup effects, such as the pronounced response in eyes with baseline accommodative amplitude >2.0 D

Strengths

• Data originates from a randomized, parallel-group, double-masked clinical trial with a 1:1 allocation ratio, suggesting a rigorous study design.
• The trial reported specific, statistically significant results, including a -1.75 point adjusted mean difference in CVS-Q score and a 1.09 D improvement in binocular accommodative amplitude.
• High participant adherence was reported, with mean compliance of 98.2% in the treatment group and 97.5% in the sham group.
• No treatment-related adverse events were reported among the 64 participants who completed the trial.

Limitations

• Row count is unknown, which may limit suitability assessment for certain analyses.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 203.2 KB size indicates a very limited scope, likely containing summary results rather than individual participant-level data.
