To ascertain whether gender inequities exist regarding cataractsurgery in Latin America.


A meta-analysis (fixed effects model and random effect modelin 1 case) was conducted using original Rapid Assessment ofCataract Surgical Services/Rapid Assessment of Avoidable Blindnessstudy data from 11 countries to determine differences in cataractsurgical coverage (CSC) between males and females (9046 eyes).Odds ratio (OR) of having had cataract surgery was the mainoutcome using males and females as the 2 groups.


On an eye basis, pooled CSC results with a visual acuity (VA)< 20/400 showed a nonsignificant OR of 1.03 (95% confidenceintervals [CI]: 0.91-1.17) for women obtaining cataract surgeryin comparison to men. When VA was < 20/60, a nonsignificantOR of 1.03 (95% CI: 0.93-1.14) was calculated favoring men overwomen. For VAs of < 20/400 and < 20/60 on a person basis,nonsignificant ORs of 1.10 (95% CI: 0.78-1.55) and 1.04 (95%CI: 0.89-1.20) were found in favor of women and men, respectively.Significant heterogeneity was encountered only on a person basisat a visual acuity of < 20/400, where a random effects modelwas employed. Otherwise, heterogeneity was low or moderate.


Gender does not appear to be a significant factor in regardto cataract surgery in Latin America, although more researchwill need to be done to firm this finding.
