To compare Kaplan-Meier survival curves and funnel plots for the audit of surgeon-specific corneal transplantation outcomes. We obtained data on all patients with Fuchs endothelial dystrophy (FED) receiving a first corneal transplant in one eye between January 2012 and December 2017. We produced 2-year Kaplan-Meier graft survival curves to compare a simulated individual surgeon's graft survival rate to national pooled data. We used funnel plots to compare all surgeon outcomes to the national graft survival rate with superimposed 95 and 99.8% confidence limits. We defined an outlier as a surgeon who performed ≥10 transplants and had graft survival below the 99.8% national lower limit. To assess the effect of the surgeon case mix, we also compared unadjusted and risk-adjusted graft survival rates. There were 3616 first corneal transplants for FED patients with complete data, performed or overseen by 196 surgeons. The 2-year national graft survival rate was 88%. The median change from the unadjusted to the risk-adjusted graft survival rate for individual surgeons was 0% (IQR: 0%- -2%). Of the 108 surgeons who had performed ≥10 transplants, we identified two outliers based on the unadjusted graft survival funnel plot, compared to four outliers based on the risk-adjusted graft survival funnel plot. Funnel plots provide a visually accessible method for comparing individual graft survival rates to the national rate. Risk-adjustment accounts for clinical factors, and this has advantages for audit and clinical governance.
