Although previous research has implicated aqueous humor uric acid in cataract pathogenesis, its invasive measurement method limits clinical utility. Consequently, the association between readily accessible serum uric acid levels and cataract risk remains poorly defined.

However, these associations were no longer statistically significant after full adjustment for demographic, socioeconomic, and cardiometabolic covariates (CHARLS, odds ratio: 1.09, 95% confidence interval: 0.98\u20131.22; NHANES, odds ratio per SD: 1.05, 95% confidence interval: 0.98\u20131.12).
