Monitoring and evaluating cataract intervention in India.
OBJECTIVE
To identify indicators to monitor and evaluate the cataract intervention programme in India.


METHODS
Available data on blindness due to cataract, demography, staffing levels, and infrastructure available under the programme were reviewed. Four key elements of the programme were identified: the magnitude of blindness due to cataract and the need for surgical services; the available resources; the output, in quantity and in quality, as well as the resource utilisation; and lastly the impact this has on society and the problem of blindness due to cataract. Indicators to quantify these key elements were designed and available data were used to calculate the defined indicators.


RESULTS
At least 2.5 million sight restoring cataract operations will have to be performed annually. Staffing levels and infrastructure resources at present allow for increased output. The effectiveness of cataract services can be increased with better case selection.


CONCLUSIONS
The use of these indicators provides an insight into the dynamics of the problem of cataract blindness and its intervention. They facilitate adequate management and evaluation of the efficiency and effectiveness of the intervention programme and may ensure optimal utilisation of the available resources for cataract surgery.
