Abstract:
Tamsulosin is an alpha(1)-adrenergic antagonist known to be linked with intraoperative floppy-iris syndrome (IFIS), which is characterized by iris atonicity and a propensity toward progressive intraoperative pupil constriction and iris prolapse. We present 2 strategies for managing IFIS-associated iris prolapse. Placement of a single subincisional iris retractor following reposition of the prolapsed iris was the more successful approach. We recommend consideration of this approach in all cases of iris prolapse.
