Methods: Eleven electronic databases and reference lists of relevant studies were systematically searched. Two reviewers independently screened records, extracted data, and assessed study quality. Pooled effect sizes were calculated using a random-effects model with standardized mean differences (SMD) and relative risks. Heterogeneity was assessed using the I² and Chi-square tests, with subgroup, sensitivity, and publication bias analyses performed. Results: Twenty-two studies met the inclusion criteria, and 13 were included in the meta-analysis. Interventions included educational, telephone-based, and health promotion programs. Educational programs significantly improved attitudes toward eye health (SMD = 3.91) and general eye health behaviors (SMD = 8.20). Structured teaching interventions had the greatest effect on knowledge (SMD = 4.04), while community-based support groups improved eye examination uptake (SMD = 4.33). Subgroup and meta-regression analyses found no significant moderators, with persistent heterogeneity. Conclusion: Community-based interventions appear to enhance eye health knowledge and behaviors among older adults, but evidence remains limited and heterogeneous, warranting cautious interpretation.
