floppy iris syndrome associated with tamsulosin(IFIS)
JCRS APRIL 2005
USA.A retrospective chart review of consecutive cataract surgeries performed in a 2-surgeon practice over a 12-month period (706 eyes; 511 patients) was used to assess the percentage of cataract patients on systemic sympathetic α-1 antagonist medications as well as the percentage of patients who manifested the IFIS.
Conclusion
Intraoperative floppy iris syndrome occurred in approximately 2% of a cataract surgery population and appeared to be caused by tamsulosin, a systemic sympathetic α-1A antagonist(Flomax) medication that is the most frequently prescribed medication for benign prostatic hypertrophy. Sphincterotomies and mechanical pupil stretching were ineffective in maintaining adequate pupil dilation in this surgical population.
