Changing practice patterns in European cataract surgery as reflected in the European Registry of Quality Outcomes for Cataract and Refractive Surgery 2008 to 2017

In Brief Purpose: To study practice patterns in European cataract surgery over a 10-year period. Setting: clinics affiliated to the Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO). Design: cohort study. Methods: The EUREQUO contains preoperative, intraoperative, postoperative parameters reported by surgeons many clinics. All data registry are anonymized. Preoperative included age, sex, visual acuity, target refraction, ocular comorbidity, surgical difficulties. Surgical anesthesia, technique, intraocular lens optic biomaterial, complications. Postoperative short-term Results: During period (January 1, 2008, December 31, 2017), total 2 714 108 extractions were EUREQUO. changed time, with decreases mean age (74.5–73.0 years), proportion women from 60.6% (100 373/165 628) 57.2% (174 908/305 845), coexisting eye diseases 30.0% (49 638/165 650) 27.0% (82 704/305 846) improvements preoperative acuity (mean logarithm minimum angle resolution [logMAR] 0.46 0.37). use topical anesthesia increased time 28.1% (26 238/93 320) 71.7% (130 525/182 083). complications showed significant decrease 2.5% (4107/165 1.2% (3573/305 846). outcome improved logMAR 0.08 0.05), as did absolute median prediction error (0.38 diopter [D] 0.28 D). Conclusions: Trends 2008 2017 have moved toward younger patients better fewer complications, predicted refractions outcomes. Preoperative, surgical, outcomes more than 2.7 million decade described.
