Purpose To study associations between intraoperative difficulties and changes in patient‐perceived and postoperative visual function and visual satisfaction after cataract surgery. Methods Swedish multicenter, prospective, cross‐sectional, nonrandomized, National Cataract Register study. A total of 10 979 patients ( n = 10 979) who underwent cataract surgery from 2008 to 2011 completed the Catquest‐9 SF questionnaire before and 3 months postoperatively. Using Rasch analysis, we converted the nonparametric grading of the answers to parametric data and performed parametric statistical analyses. Multiple regression models were used to examine possible predictors associated with self‐assessed visual function after cataract surgery. Results Greater improvement in self‐assessed visual function was seen in patients in whom trypan blue dye was used; those without a posterior capsular tear or an ocular comorbidity; and those who were younger, female and had low preoperative corrected distance visual acuity ( CDVA ) or high postoperative CDVA compared with their counterparts. Significantly higher self‐assessed postoperative visual function was seen in patients in whom trypan blue dye was used and those with no posterior capsular tear or ocular comorbidity and no use of capsular hooks; and those who were younger and had low preoperative or high postoperative CDVA compared with their counterparts. The risk of general dissatisfaction after cataract surgery was significantly greater in patients with a posterior capsule tear, ocular comorbidity or low postoperative CDVA , and those in whom mechanical pupillary stretching was performed. Conclusion Several intraoperative difficulties, posterior capsular tear, ocular comorbidity, age, gender, and preoperative and postoperative CDVA s affect patient improvement and self‐assessed visual function after cataract surgery.
