Sponsor's own description
Intraoperative Floppy Iris Syndrome (IFIS) is a potencial complication encountered during cataract surgery in patients treated with α1-adrenergic receptor antagonists (α1-ARAs) for lower urinary tract symptoms. Therefore, careful assessment of pharmacological history is essential during the preoperative biometric evaluation of patients indicated for cataract surgery. In this study, the investigators expand the standart preoperative assessment by incorporating measurements of iris thickness at the level of the dilator and sphincter pupillae muscles, as well as pupil diameter, using anterior segment optical coherence tomography in patients receiving α1-ARAs. The aim of the study was to determine whether these parameters are associated with the intraoperative risk of IFIS development.
