Figure 22.

Box and whisker charts showing cataract surgical coverage and effective cataract surgical coverage in Vietnam. The data show increasing coverage between 2000 and 2015 and decreasing coverage as the visual acuity thresholds for operable cataract and good clinical outcome are increased.

Cataract surgical coverage in Vietnam

(A) Cluster-adjusted, age-adjusted, and gender-adjusted data from subnational Rapid Assessment of Avoidable Blindness surveys done in Vietnam in 2000–02 (n=8), 2007 (n=16), and 2015 (n=14), estimated for an operable cataract threshold of worse than 6/60 and a good clinical outcome of 6/18 or greater. (B) Data from 14 subnational surveys done in Vietnam in 2015. Data are plotted for three thresholds of operable cataract and two different levels of vision outcome: 6/18 or better and 6/12 or better. Box and whisker plots; midlines are the median, boxes represent IQR, whiskers are upper and lower adjacent values. Outliers are plotted as individual dots. CSC=cataract surgical coverage. eCSC=effective cataract surgical coverage.
