[Managing complications in intraoperative floppy iris syndrome]

The intraoperative floppy iris syndrome (IFIS) describes an ophthalmologically relevant phenomenon which is observed after systemic intake of alpha blockers for treatment of benign prostate hyperplasia. This leads to an increase in intraoperative complications in cataract surgery characterized by a flaccid iris which billows in response to currents with a tendency to prolapse towards the area of surgery. This results in damage to the iris by the instruments used or posterior capsule rupture with loss of lens material. We describe the preoperative and intraoperative measures and techniques to deal with this challenging situation in order to minimize development of IFIS and reduce the complication rate.
