Abstract Details


Intraoperative floppy iris syndrome (IFIS) is a complication characterized by a flaccid iris which billows in response to ordinary intraocular fluid currents, a propensity for this floppy iris to prolapse towards the incisions during surgery, and progressive intraoperative pupil constriction that may occur during cataract extraction in certain patients, associated widely with medications prescribed for urinary symptoms. To determine the incidence of IFIS in patients who underwent cataract surgery and the relationship with previous visits to the urology service in our environment.


Department of Ophthalmology, Hospital Parc Taulķ Sabadell, Universitat Autņnoma de Barcelona, Catalunya


A retrospective chart review of consecutive cataract surgeries performed between January 2006 and December 2007. IFIS was defined by the reported presence of any of the three signs that constitutes the syndrome: Suspicion of IFIS was defined by the presence of incidents directly related to an abnormal behavior of the iris. Surgical times were recorded, the presence of ripple iris prolapse of the iris, pupillary constriction and complications. The visits to the urology service previous to the surgery were recorded; as an indirect measure of medications prescribed for urinary symptoms intake.


The review of 4406 records identified 49 patients (56 eyes) who had IFIS or were suspected of IFIS at the time of surgery. The overall incidence of IFIS was 1.27%. The incidence of IFIS or IFIS suspected was significantly associated with the previous visit to the urology service (p = 0.01). In the group of patients with previous visit to the urology department succeeded 4 posterior capsule ruptures that could be associated with IFIS.


The incidence of IFIS may be related to the previous visit to the urology department of the patients. The occurrence of IFIS was associated with higher surgical times. The incidence of IFIS in the rate was lower than most publications but are consistent with other retrospective studies. FINANCIAL DISCLOSURE?: No
