Abstract Purpose To analyse the relationship between patient‐reported outcome measures and clinical outcome measures in 42 individual S wedish cataract surgery settings. Methods The study material consisted of follow‐up data on cataract extractions collected by the S wedish N ational C ataract R egister in 2008–2011. Patient‐reported outcome was measured using the Catquest‐9 SF questionnaire. A total of 9707 pairs of questionnaires completed before and after a cataract extraction were analysed together with clinical data. The analyses were performed for each clinic. Results For almost all clinics, a factor related to a poor patient‐reported outcome after surgery was a good preoperative self‐assessed visual function. For some clinics, up to 50% of the patients stated that they were very satisfied with their vision before surgery. For single clinics, different factors such as large anisometropia (≥3D), capsule complications, biometry prediction error (≥3D) and ocular comorbidity were related to a poor patient‐reported outcome. In situations where the clinical outcome was good and the patient‐reported outcome was poor, problems with near‐vision activities after surgery was the main factor noted. Conclusions Analysing factors related to a poor patient‐reported outcome for each clinic showed large variation. Weak indication for surgery, refractive problems after surgery, surgical complications and a poor chance of visual recovery due to ocular comorbidity were among the reasons for a poor patient‐reported outcome. Post‐operative care in terms of establishing a good near vision seemed to be another problem for some clinics.
