This study aimed to identify factors associated with reduced ophthalmic medical access during the pandemic.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This nationwide population\u2010based cohort study analysed South Korean health insurance claims data from January 2019 to November 2021. Outpatient visits and surgeries for age\u2010related macular degeneration, cataract, diabetic retinopathy, glaucoma, and retinal detachment during the two pandemic waves were compared with those in the non\u2010pandemic period. Poisson regression was used to estimate incidence rate ratios and changes in outpatient visits and surgeries between waves concerning patient age, sex, residential location, and health insurance type.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Outpatient visits for five eye diseases decreased in the first wave (0.733\u20130.985, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). In the second wave, only outpatient visits for age\u2010related macular degeneration, cataract, and glaucoma decreased (0.754, 0.878, and 0.874, respectively, all <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Age\u2010related macular degeneration, cataract, and glaucoma surgeries were significantly reduced in the first wave (0.829, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001; 0.836, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001; 0.904, <jats:italic>P<\/jats:italic>\u2009=\u20090.030, respectively). Age\u2010related macular degeneration (0.852) and cataract (0.716) surgeries dropped in the second wave. Women and elderly (&gt;65\u2009years) patients curtailed outpatient visits and surgeries more throughout the pandemic and were less resilient during the second wave.
