The main objectives of this study were: To assess the incidence of the intraoperative floppy-iris syndrome associated with tamsulosin and to analyse the incidence of intraoperative and postoperative complications as compared to a control group. Secondary objectives were: to describe the pupillary modifications associated with tamsulosin and to quantify the endothelial cell loss.A prospective review of 38 eyes of 38 patients was performed. Patients were assigned to two different groups. Group 1 (cases) included 19 eyes of 19 male patients taking tamsulosin, and group 2 (controls) included 19 eyes of 19 male patients not taking tamsulosin.Only two patients (10%) of our study had the complete triad seen in floppy-iris syndrome; 9 patients (47%) showed 2 of the 3 main features of the syndrome and only 2 patients showed iris billowing during phacoemulsification. None of the patients in group 2 showed any of the characteristic intraoperative features. The complication rate was similar in both groups.Intraoperative floppy-iris syndrome occurred in 67% of the patients treated with tamsulosin. The only postoperative secondary effect was a lower pupil reactivity in patients taking tamsulosin.
