In 2004 Fidel Castro and Hugo Chavez made a deal to significantly expand eye surgery in Cuba and Venezuela to eliminate blindness from cataracts and other reversible eye conditions. Venezuela had oil cash so it provided the equipment. Cuba had the doctors so it rapidly expanded the number of ophthalmologists it trained. At first the patients came from Venezuela to Cuba by the thousands but over time the Cuban ophthalmologists went abroad to serve more people near their homes. By the time the formal program ended, more than 3 million people in Latin America and Africa benefited from it. Now, Cuba remains a center for eye related medical tourism.
