Vision Centers for Eye Care Access and Outcomes in South Asia

This study is looking at how setting up "vision centers" affects access to eye care and eye health in South Asia. Vision centers are fixed locations with trained staff who offer basic eye care like checking eyesight, providing glasses, and diagnosing common eye problems. They also refer people for more advanced care. Researchers want to see if these centers improve how many people get their eyesight corrected (refractive error coverage), if more people use eye care services, and if people's vision gets better. You could be part of this study if you live in a rural area, 20-100 km from a main hospital, and there aren't many other eye care services nearby. The study will measure eyesight correction after two years. The current status of this study is unclear.

Study design
This is an interventional study involving 150,000 participants. It's a cluster-randomized trial, meaning communities will be randomly assigned to either get a vision center right away or at a later time.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Your eyesight correction will be measured after two years.

Eligibility criteria

Inclusion

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.

Exclusion

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.

What this trial measures

    Proportion of survey participants with met need for distance refractive error correction with good quality vision of 6/12 or better in the better seeing eye among the total number of people in need (met need + undermet need + unmet need).
