To examine variation in intraoperative clinical practice and rates of adverse events after cataract surgery across four different healthcare systems.
Multicenter cohort study.
Patients were recruited from ophthalmic clinics in the United States (n=75) ; in the Province of Manitoba, Canada (n=12) ; in Denmark (n=17) ; and the City of Barcelona, Spain (n=10).
In all, 1420 patients undergoing first eye cataract surgery were enrolled, with preoperative, perioperative, and postoperative clinical data collected on 1344 patients (95%). Main Outcome Measures : Occurrence of 23 specified intraoperative and early postoperative adverse events was measured.
Four-month postoperative visual acuity outcome also was measured.
Phacoemulsification was performed in two thirds of the extractions in the United States and Manitoba, in one third in Denmark, and in 3% in Barcelona (P<0.001).
More than 96% of extractions in North America and Denmark were performed with the patient under local anesthesia, whereas general anesthesia was used for 38% of extractions in Barcelona (P<0.001).
Rates of intraoperative adverse events were 11% to 12.8% in Manitoba, Denmark, and Barcelona and significantly lower in the United States (6%), mainly because of a lower rate of capsular rupture (P<0.01).
Significantly higher rates of early postoperative events were seen in the United States (18.8%) and Manitoba (20.4%) compared to Denmark (7. (...)
