The backlog for providing cataract surgery is huge and is getting larger every year. Seva volunteer ophthalmologist and Board member Dr. Marty Spencer recently traveled to Instituto Mexicano de Oftalmología in Querétaro, Mexico to teach additional doctors to perform sight-saving surgeries. The ophthalmologists came from all over Mexico, as well as a few from other countries in Latin America. This training will increase capacity to address the surgical backlog and end needless blindness that affects so many people throughout Latin America.
