Influence of Refractive Surgery Complications on Quality of Life
A number of questionnaires exist for the measurement of quality of life (QOL) in the refractive surgery patient, but not all questionnaires are equal in validity.
Rasch analysis is important in the development of questionnaires to optimize question inclusion, unidimensionality, and to provide valid linear scoring.
A quality of life instrument should include a breadth of content areas, e.g., well-being, convenience, and concerns, not just functioning or satisfaction.
QOL instruments readily demonstrate the benefits of refractive surgery.
A sound QOL instrument is also sensitive to the negative impacts of surgical complications, providing an insight into the real impact of the intervention on the person.
