November 2017 in “DOAJ (DOAJ: Directory of Open Access Journals)” This study found an IFIS incidence rate of 3.18% among cataract surgeries in a Chinese hospital and identified reserpine, clozapine, and post-panretinal photocoagulation as new risk factors.
August 2024 in “Journal of Personalized Medicine” In this study using a rabbit model, higher incidences of intraoperative floppy iris syndrome were observed in animals given the α-blocker tamsulosin, suggesting a potential association with increased iris billowing during eye surgery.

June 2011 in “Acta Ophthalmologica” This study found that current use of benzodiazepines, α1-blockers (like tamsulosin, alfuzosin, terazosin), finasteride, and possibly rivastigmine is associated with increased risk of intraoperative floppy iris syndrome in cataract surgery patients.
