Abstract Details


To assess surgeon characteristics associated with reported adverse events in penetrating keratoplasty (PK) and descemet's stripping automated endothelial keratoplasty (DSAEK) during the early postoperative period.

We compared surgeon characteristics for corneal tissues used in PK and DSAEK between 2007 and 2011 including tissues with reported adverse events. Sub-group analysis was performed to evaluate for surgeon-related adverse events, defined as those due to surgeon inexperience or intraoperative complications.


Of 13,550 tissues included, there were 204 (1.51%) reported adverse events – 135 in DSAEK and 69 in PK. The adverse event rate was 0.90% in PK versus 2.29% in DSAEK. DSAEK surgeons were more likely to be fellowship trained (P=0.04) and work in cornea sub specialty practices (P=0.02) than PK surgeons. Both overall and surgeon-related adverse event rates were significantly higher in DSAEK compared to PK (P<0.0001). Surgeons working in cornea sub specialty practices had lower adverse event rates (P=0.02 in DSAEK, P=0.01 in PK). Lower surgeon-related adverse events were also associated with greater surgeon experience (P=0.04) in DSAEK.


The rate of reported adverse events was low. Overall and surgeon-related adverse events were more common after DSAEK. A small number of high-volume surgeons account for a large proportion of all surgeries. While greater surgeon experience was associated with lower adverse events in DSAEK, the effect was minimal once a surgeon had performed at least ten cases a year.
