Journal of patient-reported outcomes·2025

Patient-reported outcome measures are crucial for evaluating surgical procedures. This review assesses the quality of patient questionnaires for cataract surgery activity limitations published since 1992.

Area of Science:

  • Ophthalmology
  • Health Outcomes Research
  • Psychometrics

Background:

  • Patient-reported outcomes (PROs) are vital for assessing surgical procedure effectiveness.
  • Numerous patient questionnaires exist to measure activity limitations due to cataracts.
  • Questionnaire development and evaluation methodologies have evolved.

Purpose of the Study:

  • To review and evaluate the psychometric properties of patient questionnaires for cataract-related activity limitations.
  • To assess questionnaires published from 1992 onwards.
  • To include instruments developed using both classical test theory and item-response theory.

Main Methods:

  • Systematic literature search for relevant patient questionnaires.
  • Evaluation of psychometric properties (validity, reliability, responsiveness).

  • Inclusion of questionnaires based on classical test theory and item-response theory.

    • Main Results:

    • Identified and analyzed various patient-reported outcome questionnaires for cataract surgery.
    • Assessed the methodological quality and psychometric performance of these instruments.
    • Highlighted the evolution of questionnaire evaluation techniques since 1992.

    Conclusions:

    • The quality of patient-reported outcome measures for cataract surgery varies.
    • Understanding psychometric properties is essential for selecting appropriate instruments.
    • Continued refinement of questionnaire methodology enhances outcome assessment in ophthalmology.
