Trends in infectious adverse events after elective optical keratoplasty (PK, EK, and ALK) - Ten years’ analysis from an eye bank

The overall risk of infectious adverse events after keratoplasty was 0.11%, ranging from 0.08% to 0.36%. Most (80.4%) of the adverse events occurred after EK. The majority (78.9%) of the adverse events were of bacterial etiology, of which gram-negative infections (68.4%) were the most common. The trends and microbiological spectrum of organisms associated with infections should be thoroughly documented in eye banks to gain insights and formulate guidelines on the management of adverse events.
