The main questions it aims to answer are:\n\n1. Do vision centers improve effective refractive error coverage?\n2. Do vision centers increase eye care center utilization?\n3. Do vision centers improve population visual acuity?\n\nResearchers will compare outcomes in communities randomized to immediate versus delayed establishment of a vision center. Outcomes will be assessed through population-based surveys at baseline and after two years as well as through hospital records collected throughout the study period.",[26,27,28,29,30,31],"Cataract Surgery","Eye Care","Glasses","Primary Eye Care","Vision Center","Eyecare Visits",[33,34,35,36,37,38,39,40],"vision center","primary eye care","cataract surgery","glasses","glassess ownership","spectacle ownership","cluster-randomized trial","eyecare visits","NOT_YET_RECRUITING","2026-06-26",{"date":44,"type":45},"2026-06-30","ACTUAL",{"date":47,"type":20},"2026-08-01",{"date":49,"type":20},"2028-12-01",{"name":51,"class":52},"University of California, San Francisco","OTHER"]
