Satisfaction with correction, glare, symptoms, clarity of vision, worry, and quality of far vision scores were assessed by and compiled from RQL responses. So that the subscales would operate the same regardless of category, higher scores were assigned to a more favorable outcome (eg, a higher “worry” score to represent a better outcome, or less worry). The RQL is written so that certain questions refer specifically to defined areas including satisfaction with correction, glare, symptoms, clarity of vision, worry, and quality of far vision. The mean of questions 23, 37, 39, and 40 from the NEI-RQL Instrument measure clarity of vision; the mean of questions 21 and 22 assess worry; question 26 measures satisfaction with correction; glare is quantified by responses to questions 17 and 38; symptoms such as pain, itching, dryness, and fatigue are measured by questions 18, 19, 24, 25, 36, 41, and 42; and far vision score is the mean of questions 4, 5, 6, 9, and 10. In examining and evaluating RQL responses in a defined area, study personnel referenced component questions and evaluated the specific scores of the component questions.
