Organisation of findings. Reviews will be divided according to the question they address (question 1 being vision impairment/eye disease, and question 2, ophthalmic interventions). For each question, reviews will be categorised as quantitative or qualitative, and within each category, they will be further grouped based on their quality-of-life measure and exposure (specific functional vision measure or eye disease for question 1, and intervention for question 2). Summary of findings tables will be further stratified by study population depending on the results available; potential subgroups include age category (children, working-age adults or older adults), country (low, middle or high income) or setting (community, hospital, clinic, institution).
