About this trial

This cluster-randomized trial aims 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 improve effective refractive error coverage? 2. Do vision centers increase eye care center utilization? 3. Do vision centers improve population visual acuity?

Researchers 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.

Eligibility criteria

Qualifiers

The catchment area of the proposed VC site is predominantly rural.

The proposed VC site is located within 20-100 km of the base hospital.

There are no major primary eye care services within 10 km of the proposed site.

Care at sites randomized to establish VCs immediately is accessible to anyone.

Disqualifiers

Sites located in non-rural or urban catchment areas.

Sites outside the 20-100 km distance range from the base hospital.

Sites with existing major primary eye care services within a 10 km radius.
