Summary
The Catquest questionnaire demonstrates high validity and reliability for assessing visual disabilities in cataract patients. This self-assessment tool aids surgeons in quality control for cataract surgery outcomes.
Area of Science:
- Ophthalmology
- Patient-Reported Outcomes
- Quality Improvement in Healthcare
Background:
- Cataract surgery aims to improve vision and quality of life.
- Continuous quality control is essential for surgical appropriateness and outcomes.
- Patient self-assessment tools can provide valuable data on functional vision and satisfaction.
Purpose of the Study:
- To describe the Catquest self-assessment questionnaire.
- To evaluate the validity and reliability of the Catquest for cataract patients.
- To assess its utility for quality control in cataract surgery.
Main Methods:
- The Catquest questionnaire was administered to patients before and after cataract surgery.
- It assessed visual disabilities, daily activities, and independence.
- Data were collected from consecutive patients across 35 Swedish ophthalmology departments.
Main Results:
- The Catquest showed a strong correlation between visual disability and general vision opinion (P < .001).
- High test-retest reliability and internal consistency were observed (P < .001).
- Pre-operative patient responses differed significantly from a control group (P < .0001).
Conclusions:
- The Catquest is a valid and reliable disease-specific instrument for evaluating visual function in cataract surgery patients.
- It provides valuable data for quality assessment of cataract extraction.
- The questionnaire aids in understanding patient-reported visual outcomes.
