Effective cataract surgical coverage (eCSC) (age-sex adjusted)

The RAAB research team did a formal analysis of eCSC with the World Health Organization and the Vision Loss Expert Group in late 2022. eCSC results will be available on the repository in 2023.

Notes

Vision impairment categories defined according to WHO thresholds using presenting visual acuity in the better eye.

All prevalence and coverage estimates are adjusted to the age and gender distribution of the population 50 years and older in the survey area.

All 95% confidence intervals adjusted to account for the cluster design of the survey.
