Effect of Vision Centers on Access to Eye Care and Eye Health Outcomes
Sponsor: University of California, San Francisco
Summary
The goal of this clinical trial is to evaluate the effect of vision centers on access to eye care and eye health outcomes in South Asia. The main questions it aims to answer are: 1. Do vision centers increase visits to eyecare centers? 2. Do vision centers increase spectacle ownership and wearing? 3. Do vision centers improve visual acuity of the population? Researchers will compare outcomes in communities randomized to have a vision center is established with communities randomized to delay 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.

Interventions
Establishment of a vision center
The establishment of a vision center includes building a fixed center, and equipping it with a trained vision technician to provide basic eye care services such as refractive error correction, spectacle dispensing, basic diagnosis for common conditions, as well as referrals for advanced care at base hospitals. The establishment of VCs will be actively publicized in the neighboring communities through promotion by local stakeholders, teachers, community workers, village leaders, health workers, and radio announcements prior to establishment. Additional outreach activities include posters and loudspeaker announcements in the communities the day before operations begin.
