PURPOSE: To assess the correlation between visual acuity, visual function, and health-related quality of life before and after neodymium:YAG laser posterior capsulotomy. METHODS: A total of 150 patients with posterior capsule opacification (PCO) were examined before and after capsulotomy. Ocular examination, visual acuity, patient reports of satisfaction with vision, and disease-specific (VF-14 Index of Visual Functions) and generic (EuroQol: EQ-5D) outcomes were measured at baseline and 3 weeks after treatment. RESULTS: After capsulotomy, patients showed significant improvements in binocular visual acuity, VF-14 index, satisfaction with vision, and EQ-5D measures. The average gains in visual function and quality of life were apparent in groups with good visual outcome and poor visual outcome. The VF-14 score improvement was moderately correlated with the EuroQol Visual Analogue Scale score improvement, showing stronger correlations with changes in self-reported satisfaction with vision than did gains in binocular visual acuity. CONCLUSIONS: Measuring of the outcomes of capsulotomy by clinical indicators alone may underestimate the overall benefits of treatment. Visual acuity in conjunction with visual function and health-related quality of life questionnaires will likely prove to be better indicators of the need for and outcome of capsulotomy.
