Iris damage occurred in 2 patients due to the inadvertent forceful injection of a cannula. Despite luer lock syringes, the J-shaped cannula was injected during cortical removal in one eye and during hydration of the incision at the end of the procedure in the second eye. Iris damage should be added to the growing list of injuries that can result from cannula-related complications.
