Cataract as a Cause of Blindness and Vision Impairment in Latin America: Progress Made and Challenges Beyond 2020

center dot PURPOSE: To provide an update of cataract as a cause of vision loss in Latin America and to analyze sex inequalities in cataract surgical coverage (CSC) and effective CSC (eCSC) in the region. center dot DESIGN: Population-based systematic review with longitudinal comparisons. center dot METHODS: The Latin American and Caribbean Health Sciences Literature (LILACS) and PubMed databased were searched for population-based studies reporting cataract blindness, surgical coverage, and outcomes published between January 2014 and December 2019. Information on the number of surgeries performed from the 2014-2016 period was obtained from ministries of health and was used for calculation of the cataract surgical rate (CSR). Sources such as Rapid Assessment of Avoidable Blindness (RAAB) and Rapid Assessment of Cataract Surgical Services data were reanalyzed to calculate sex inequality in CSC and eCSC by subtracting the rate in women from the rate in men. center dot RESULTS: Cataract was the cause of 29.8%-77.6% of cases of blindness in the included studies; the CSR improved in 10 countries. The CSC pinhole visual acuity of 3/60 varied from 24.1% in Peru to 97.1% in Argentina, and the median absolute gender inequality CSC pinhole visual acuity 3/60 was-0.7%. The eCSC pinhole visual acuity 3/60 varied from 14.8% in Guatemala to 92.1% in Argentina, and the median absolute gender inequality eCSC pinhole visual acuity 3/60 was-0.8%. center dot CONCLUSIONS: Cataract remains a leading cause of blindness in Latin America. Coverage is suboptimal, and surgical results are also below target levels in many countries. Incentives for a better distribution of human resources, adequate training of ophthalmologists, and the inclusion of vision services in universal health care coverage could reduce the burden of cataract in Latin America.
