To investigate the change in proportion of high-volume cataract surgeons during the period 2007 to 2016 and determine the impact of operation volume per surgeon and clinical unit on the rate of capsule complications.
Retrospective, register-based study.
Patients undergoing and surgeons performing cataract surgery at Swedish ophthalmologic departments 2007-2016.
All cataract procedures performed during a 10-year period were analyzed, and the change in operation volume of individual surgeons over time was determined. The yearly incidence of capsule complications was correlated to the operation volume of individual surgeons and clinical units.
The number of cataract procedures yearly per surgeon and clinical unit, proportion of capsule complications, and change over time in operation volume and complication rate.
The proportion of high-volume (=500 procedures yearly) and very high-volume (=1000 procedures yearly) surgeons increased from 15.0% to 34.0% and 2.1% to 10.9%, respectively (P
