Abstract Details


Patient Reported Outcome Measures (PROMs) collects information on the effectiveness of care delivered to NHS patients as perceived by the patients themselves. Although there is a push to extend PROMs across the National Health Service, there is currently a lack of guidance for patients undergoing cataract surgeries. It is also unclear if the generic health questionnaire recommended was suitable for cataract patients. This study assesses the performance of different questionnaires to determine their appropriateness for cataract patients in UK.


: Patients awaiting cataract surgery at Moorfields Eye Hospital between February and March 2013 were recruited for the study.


A study pack of four questionnaires, consisted of Catquest-9SF (cataract and visual function specific questionnaire), EQ-5D-5L (generic health questionnaire), NEI-SES (socio-emotional specific questionnaire) and VF-8R (cataract and visual function specific questionnaire) were given to patients to complete during pre-assessment appointment, 2 weeks post-surgery and 3 months post-surgery. Data were Rasch-analyzed when possible to allow direct comparison of the performance of the questionnaires.


Fifty-five patients were recruited to date, with 25 patients completed 3 months follow-up. All questionnaires shows correlate with visual improvement. The change in Rasch-analyzed scores for Catquest-9SF, EQ-5D-5L, NEI-SES and VF-8R at 2 weeks post-surgery were 147.37% (p=0.01), 3.89% (p=0.79), 0.48% (p=0.91) and 12.44% (p=0.23) respectively. These change at 3 months were 105.65% (p<0.01), 4.13% (p=0.37), 45.65% (p=0.09) and 41.37% (p=0.18), respectively.


Collecting patient reported outcome in cataract surgery is feasible and should be introduced into daily clinical practice. Improvements in visual function could be detected as early as 2 weeks post-surgery by Catquest-9SF, while socioemotional changes may be a delayed effect of cataract surgery. FINANCIAL INTEREST: NONE
