Eye health data is the foundation for eliminating preventable blindness and vision loss. Precise, local eye health data helps estimate the burden of blindness and visual impairment, identify barriers to community participation, understand the causes of service backlogs and guide programme decisions tailored to the needs of each intervention area.

To help bridge this critical data gap in one of our key intervention geographies, Operation Eyesight has formally launched the Rapid Assessment of Visual Impairment (RAVI) Study in Pushprajgarh Block, Anuppur District, Madhya Pradesh.

Here is how this milestone initiative is helping set a new standard for evidence-based eye health interventions.

The RAVI methodology: Precision at scale

To uphold scientific rigour, the study is led by two of India’s most respected institutions. The L.V. Prasad Eye Institute (LVPEI) serves as the principal investigator, while the All India Institute of Medical Sciences (AIIMS), Bhopal acts as the co-investigator.

The RAVI study is a comprehensive, community-based epidemiological survey that will provide critical insights into effective cataract surgery coverage, effective refractive error coverage, service delivery trends across institutions and the quality of care in the region. It will also examine community behaviours and identify the barriers that limit access to eye health care services. As an internationally accepted benchmark, the RAVI methodology is designed to ensure accuracy and regional representation.

To ensure reliable survey data, three survey teams, each made up of one optometrist and two community health volunteers, have been trained in the RAVI methodology and data collection processes. These teams will cover 80 randomly selected clusters across Pushprajgarh Block and examine approximately 3,700 to 4,000 participants aged 40 and older for various causes of visual impairment and blindness.

The significance: Charting unmapped territory

The significance of the RAVI study lies in what it will make possible. For the first time, this specific geography will have scientifically validated eye health data to guide planning, investment and action.

The field survey is currently underway and is expected to take approximately two months, with a final comprehensive report anticipated by September 2026. The initiative also reflects strong local governance, with ownership and commitment from the district administration, including the district collector and the Chief Medical and Health Officer (CMHO) of Anuppur district, Madhya Pradesh.

Voices from the frontline

Driving this ambitious project on the ground requires strategic vision, technical discipline and consistent local execution.

“The journey toward eliminating blindness and visual impairment is ongoing, but to gauge the impact we create within a geography, it is critical to compare the situation before and after an intervention. RAVI is more than data collection; it will guide our actions in this particular geography during the programme period and will also be critical for planning studies in adjoining similar geographies. By mapping the exact prevalence and determinants of blindness and visual impairment in Pushprajgarh, we can move from generalised care to highly targeted action. This evidence ensures our resources are deployed exactly where they will save the most sight.” — Aditya Sharma, Programme Manager

Objectives and expected outcomes

The data collected through the RAVI study is designed for both immediate action and long-term assessment.

Core objectives:

• Assess the prevalence, root causes and determinants of blindness and visual impairment in the region.
• Serve as the definitive baseline assessment for the ongoing eye health programme.
• Provide evidence to optimise intervention design, direct resource allocation and improve service delivery strategies.
• Support the Government of Madhya Pradesh and the National Health Mission in strengthening comprehensive eye health planning by extrapolating this study across the state.

Expected outcomes:

• Measured impact: Upon project completion, an endline survey using the same methodology will assess the programme’s true outcomes and impact.
• Global contribution: Given the scientific rigour of the study, the findings may be published in respected public health or ophthalmology journals, contributing to global health knowledge.

By validating public health strategies through scientific data, the RAVI study will help guide progress toward eliminating avoidable blindness and visual impairment. It will also help other organisations working in similar geographies use limited resources more effectively by documenting what works, what does not and where targeted action can have the greatest impact.

In 2024, we launched two research initiatives to identify learnings and to share our findings. In partnership with the Pragyaan Sustainable Health Outcomes (PRASHO) Foundation we started an evaluation of the survey tools that we use and an assessment of our Avoidable Blindness-Free methodology and its effectiveness. We look forward to sharing our findings with you!

Award-winning presentations at VISION 2020: The Right to Sight – India conference

Our team contributed four presentations to the VISION 2020 The Right to Sight – India conference, which brought together organizations, hospitals, research institutes and others to gain a deeper understanding of the challenges and opportunities across the eye health field. We submitted four presentations.

In 2010, Heeralal became a para medical ophthalmic assistant (PMOA) after the Government of Madhya Pradesh called for MPWs to undergo PMOA training. He conducted regular eye exams at CHC Niwas but was disheartened by having only two or three patients a day. He took part in school screenings and cataract camps as awareness grew.

In 2022, Heeralal saw a turning point when we launched our Integrated People-Centred Eye Care project in Singrauli. CHCs were upgraded to vision centres, equipped with slit lamps and essential ophthalmic tools. PMOAs received refresher training for comprehensive eye examinations to build eye care capacity. A series of targeted interventions rolled out.

We trained community health officers, accredited social health activists (ASHAs) and community health volunteers (CHVs). Screening camps were organized with a mobile vision van to boost awareness. With support from ASHAs and CHVs, Heeralal soon saw 12 to 15 patients daily.

Today, Heeralal feels more inspired than ever by the transformation in rural healthcare. His motivation grows with every person whose sight is restored.

His hope returned when a community health worker visited his home. Sriramappa took part in eye screening and was diagnosed with cataracts. Referred to our partner, Netradeep Eye Hospital (Globe Eye Foundation), Sririmappa accessed sight-restoring surgery free of charge.

Sriramappa expressed his gratitude to our donors. He is now enjoying life’s simple pleasures, especially roaming the forest with his animals, which helps to support his family.

Did you know?

There is a strong correlation between vision loss and age. People who are 50 years of age and older experience 73 per cent of all vision loss according to the IAPB Vision Atlas (2025). This puts people at risk of poverty, dependence and reduced health and well-being. At times, beliefs that vision loss is inevitable or that older people are not worthy of treatment can be barriers to overcome

Fortunately, 90 per cent of all vision loss is avoidable. This means it can be prevented or treated. Of all the treatments, cataract surgery is one of the most cost-effective solutions.
