Objective To estimate and compare the incidence of operable cataract and the desired cataract surgery rates required to eliminate cataract-related visual impairment in several Latin American settings. Methods We obtained raw data on age-specific cataract prevalence from standardized population-based surveys. We used the data in a previously described model to estimate the incidence of operable cataract at 11 sites in 10 countries across Latin America. Age-specific incidence rates were then multi...

Background: The cataract surgical rate (CSR) in Gujarat, India is reported to be above 10,000 per million population. This study was conducted to investigate the prevalence and causes of vision impairment/blindness among older adults in a high CSR area.Methods: Geographically defined cluster sampling was used in randomly selecting persons ≥ 50 years of age in Navsari district. Subjects in 35 study clusters were enumerated and invited for measurement of presenting and best-corrected visual acuity...

In 1999 the World Health Organization and the International Agency for Prevention of Blindness announced a joint programme to eliminate unnecessary blindness. The programme is called “Vision 2020—the right to sight”.1 Key to this initiative is the provision of sufficient, successful, and sustainable cataract services for all communities. The questions that therefore arise include: what is a sufficient; what is a successful; and what is a sustainable cataract service?2 Two articles in this issue ...
There are approximately 20 million people blind from cataract in the world, the majority of whom do not have access to affordable cataract surgery. This article will briefly address three questions regarding service delivery: How many cataracts need to be operated on? What are satisfactory results? How can cataract surgery be made affordable?
Objective: To analyze population-based trends in cataract extraction. Design: Rochester Epidemiology Project databases, which capture virtually all health care services provided to residents of Olmsted County, Minnesota, were used to perform retrospective cohort analyses of rates of primary cataract extractions performed between 1980 and 1994. Participants: The population of Olmsted County, Minnesota. Main Outcome Measures: Incidence rates adjusted to the age and sex distribution of the 1990 US ...

Purpose To estimate global rates of glaucoma surgery. Methods National glaucoma and national ophthalmology societies were contacted to obtain rates of glaucoma surgery for the preceding 5 years. In countries without a professional society, leading ophthalmologists or non-governmental organizations(NGO) wereapproached. Whenavailable, published literature was used for the estimates. Three levels of evidence were assigned: published data from central government or insurance registries (level I), es...
