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.
Effective cataract surgical coverage (eCSC) and cataract surgical coverage (CSC) are calculated according to the 2022 definition; eCSC is only reported where 6/12 data available.
Refractive error results, including effective refractive error coverage (eREC), only reported where 6/12 data available. RAAB6 surveys measured presenting visual acuity (not uncorrected visual acuity) so the alternative calculation for eREC is used.
