Cataract is a significant cause of visual impairment and leading cause of blindness worldwide, with most of those affected residing in developing countries. While prevention of cataract has thus far proven mostly unsuccessful, it is a condition that is highly amenable to and easily treated with surgery. Despite it being a simple and cost-effective procedure, unavailability of surgical services coupled with barriers to accessing and affording services is responsible for the overwhelming numbers in some parts of the world.

Some developing countries have successfully implemented policies and programs at a national level that have been effective in tackling the cataract burden, while others are yet to follow suit. Development of comprehensive eye care services where they are lacking, and strengthening of existing eye care systems to increase cataract surgical quality and quantity is imperative to addressing the cataract problem. Evaluation of existing services using proven performance indicators, production of adequate numbers of qualified surgeons through fortification of surgical training programs, and the use of reliable tools for the assessment of surgical quality are vital to this process.

Here, in this chapter, we discuss the global burden and distribution of cataract, risk factors for cataract development, methods for the assessment of cataract surgical output, coverage, and quality of surgical outcomes, and focus on providing examples of some successfully implemented models of cataract surgical training and delivery of care in the world.
