To compare intraoperative complication rates and visual outcomes for patients treated and not treated with tamsulosin hydrochloride who underwent resident-performed phacoemulsification, and to determine whether the recognition of intraoperative floppy iris syndrome in 2005 affected the subsequent complication rates for tamsulosin-treated patients. Methods: This comparative retrospective cohort study included 101 tamsulosin-treated eyes and 404 nontamsulosin-treated eyes from January 1, 1998, to August 31, 2008. Main outcome measures were major and minor complication rates and postoperative bestcorrected visual acuity. Complication rates were compared between

The authors were unable to detect a statistically significant effect of duration of tamsulosin use on the risk of intraoperative complications in phacoemulsification surgery.
