RAAB7 is the new generation of the Rapid Assessment of Avoidable Blindness population-based eye health survey. Delivered digitally, it enables faster, more accurate collection and analysis of secure, high-quality eye health data relevant to current eye health priorities. RAAB7 replaces its predecessor (RAAB6) and provides enhanced functionality and greater efficiencies across multiple stages of the survey. 

RAAB7 has been developed in collaboration between the International Centre for Eye Health (ICEH) at the London School of Hygiene & Tropical Medicine and Peek Vision, in consultation with a steering group made up of representatives from the global eye health sector. 

Powered by Peek technology, RAAB7 has been designed and tested over three years with leading sector organisations. It includes new and updated features based on the current eye health landscape to meet stakeholders’ evolving needs, and to enable them to capture the highest-quality eye health planning data. 

RAAB7 collects data relating to the two eye health indicators selected by the World Health Organization to monitor progress towards universal health coverage (effective Refractive Error Coverage and effective Cataract Surgical Coverage). It also includes an optional disability module using the Washington Group Short Set, a module endorsed by various United Nations agencies for disaggregation of Sustainable Development Goal indicators.

The insights RAAB7 provides drive improvements in eye health service planning with the aim of preventing avoidable vision loss in millions of people around the world.

RAAB7 has been developed with and for the eye health sector. Although it is a non-profit making venture, there is a technology license and service fee to use RAAB7. The fee meets the providers’ (Peek and ICEH’s) costs of supporting RAAB7 survey delivery. The additional ongoing software maintenance costs, as well as the costs associated with further development of the methodology and software, are borne by the providers (Peek and ICEH).

What is the difference between RAAB7 and the mRAAB app?


An earlier, interim RAAB application developed by Peek and ICEH, mRAAB, allowed users to input data using a smartphone into the previous version of RAAB (RAAB6).  Field tests demonstrated the advantages of the app in terms of eliminating the need for data validation and cleaning. However, the data entered into the mRAAB app still needed to be manually imported into other software for analysis. In addition to the powerful new RAAB7 survey features, the new RAAB7 app automatically uploads the data to the secure cloud-based server, resulting in a more efficient and streamlined process.

The RAAB6 underlying Microsoft software is no longer updated by Microsoft, or available for download from the RAAB Repository or website. Because the mRAAB (RAAB6) app was compatible only with this software we have removed it from Google Play store, where it was formerly available as a Beta (test) version.
