OPC - Organisation pour la Prévention de la Cécité / Organisation for the Prevention of Blindness.

OPC is an international NGO with specific expertise in ocular public health. It fights to preserve the sight of as many people as possible in the most deprived populations in Francophone African developing countries. Current partner countries: Congo, Guinea, Mali, Niger, Central African Republic, Chad. 

Through the development of comprehensive eye care systems, OPC first and foremost provides its expertise to establish the situation of the current eye health system and quantifies their needs. The foundation of a comprehensive eye care system consists of cascade training on the premise of establishing a patient referral system: the ophthalmologist trains the Senior Ophthalmologic Technicians (Techniciens Supérieurs en Ophtalmologie or TSOs). The TSOs then form the community health agents. OPC then provides the necessary equipment which allows the formation of local doctors (training of trainers, retraining and training on equipment).
