Pooled analysis of the ophthalmic visual quality of life questionnaire scale

Abstract

With people's attention and in-depth research on visual quality, many distinctive survey scales have been developed. The use of visual quality questionnaires is a subjective way to evaluate patients' visual quality, an expression of patients' self feelings, and an important part of reflecting visual quality. With objective detection methods, the results are more convincing. Many scales have been introduced into China and have been revised through translation, back translation, and cultural adaptation, playing an indispensable role in the visual quality evaluation system. It is particularly important to assess visual quality through psychological and sociological content, and whether the content can be appropriately combined with the subjective feelings of patients. The core of the visual quality of life survey questionnaire lies in its high repeatability. This article summarizes commonly used visual quality questionnaires, which have been verified in terms of validity, reliability, and responsiveness. The validity of the measurement scale, the consistency of the measurement results, the ability to reflect the smallest meaningful clinical changes after effective medical intervention, and the design characteristics, main application directions, and trends of the scale are listed to provide reference for clinical workers to choose appropriate survey scales.
