| The aims of this study are the conceptual development of a new PRO questionnaire and its validation using cognitive interviews and field data collected in the target group, to which a Rasch analysis will be applied. Further aims of the study are to investigate reproducibility and sensitivity to change using prospective cases to examine the "impact" of the treatment. Our main goal is to create an accurate, digital questionnaire instrument that can be completed in less than 10 minutes. A validated questionnaire for patients, manageable in its scope, should allow evaluating refractive surgery based on subjective satisfaction analyses. | — |
