Following the 2011 Fukushima Daiichi Nuclear Power Plant accident, \u223c20\u2009000 workers participated in emergency operations. This study aimed to investigate the association between cumulative low-dose occupational radiation exposure and the risk of cataract among workers enrolled in the Epidemiological Study of Health Effects in Fukushima Nuclear Emergency Workers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Data from 5773 nuclear emergency workers participating in the cohort were analysed. The cumulative lifetime occupational radiation dose was estimated by combining pre-2011 individual dose records from a nationwide nuclear radiation worker dose registry with radiation doses received during the 2011 emergency-work period. Self-reported, physician-diagnosed cataract was identified through baseline and first follow-up questionnaires. A Cox proportional hazards model was applied to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for incident cataract, with adjustments for major covariates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>More than 90% of the participants had cumulative occupational radiation exposure of &amp;lt;100 mSv, including doses received both prior to the accident and during the emergency period (March\u2013November 2011). During 52\u2009921 person-years of follow-up from 2012 to 2024 (mean, 9.2\u2009years), 310 participants reported new-onset cataract. The risk of cataract increased with lifetime occupational exposure up to November 2011, with an HR of 1.03 per 10-mSv increase (95% CI, 1.02, 1.05). This association persisted after excluding participants with doses of \u2265100 mSv. For exposure during the emergency period (March\u2013November 2011), the HR was 1.06 per 10-mSv increase (95% CI, 1.03, 1.09). When the cumulative lifetime occupational radiation dose was recalculated by using 2-year and 5-year lag periods before diagnosis or censoring, the HRs per 10-mSv increase were 1.03 (95% CI, 1.01, 1.04) and 1.01 (95% CI, 0.99, 1.04), respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n
