Purpose: Cataract represents a public health problem because patients presenting the disease are unable to adequately perform routine activities, with a negative influence on their quality of life. The purpose of this research is to evaluate the impact of reduced visual acuity on the quality of life of these patients. The authors adjusted a specific questionnaire to the Brazilian social reality and tested its response adequacy and reliability. Methods: 30 cataract patients with surgical indication were interviewed. The questionnaire was applied and the same interview was done twice within a one-hour interval. Results: More than 80% of questions were answered the first time they were asked. Consistence analysis showed that only one patient answered four questions in a different manner during the interviews. Conclusion: The authors concluded that the adjusted questionnaire is applicable to a population with a low level of formal education, being a reliable instrument in the evaluation of quality of life in cataract patients.
