Intra-operative floppy iris syndrome (IFIS) is a recently described phenomenon seen in patients undergoing cataract surgery who have taken tamsulosin, an alpha 1a-adrenergic antagonist used for benign prostatic enlargement. Incidence of even 90% has been reported in studies with majority of them being severe in nature. Prevention of intra-operative floppy iris syndrome by withdrawing tamsulosin pre-operatively has not shown consistent result. The risk of dangers of intra-operative floppy iris syndrome may be decreased by using preoperative atropine or by using visco-adaptive devices, intra-operatively.
术中虹膜松弛综合征（IFIS）是一种最近才被描述的现象，见于接受白内障手术且服用过坦索罗辛的患者，坦索罗辛是一种用于治疗良性前列腺增生的α1a肾上腺素能拮抗剂。在研究中，甚至有90%的发生率报道，其中大多数情况较为严重。术前停用坦索罗辛预防术中虹膜松弛综合征的效果并不一致。术前使用阿托品或术中使用粘弹性适应装置，可能会降低术中虹膜松弛综合征的危险风险。
