Outlines a comprehensive strategy for bringing sight-restoring surgical services to the world's estimated 15.8 million persons who are needlessly blind due to cataracts. Noting the need for a public health approach to this growing problem, the book presents arguments for the use of primary-health care services as the framework for case-finding, diagnosis, referral and follow-up. Now in its second edition, this text has been revised in line with recent techniques for cataract surgery and the availability of low-cost, high-quality intra-ocular lenses in developing countries.
