Figure 19.

Bar chart showing the approximate proportion of the population in need of cataract surgical services that actually receives the service. The purpose is to show how the proportion gets smaller at each stage in the cascade of care, from initial contact with health services to positive health outcome. For a longer description, refer to appendix 3 in the supplementary materials.
