ABSTRACT
Intraoperative floppy iris syndrome (IFIS) has been recently identified as a new small pupil syndrome during phacoemulsification. This syndrome is characterized by three intraoperative features a flaccid iris stroma that undulates and bellows in response to intraocular fluid currents; a propensity for the floppy iris stroma to prolapse toward the tip of phacoemulsification and side-port incisions despite proper wound construction; and progressive intraoperative pupil constriction despite standard preventive preoperative pharmacologic measures designed to prevent this. It is now mostly considered that IFIS is associated with the use of tamsolusin, a highly selective alpha-1A receptor antagonist for the treatment of benign prostatic hypertrophy. It is recommended that a careful history of the use of alpha-1 blocking agents be taken before cataract surgery to anticipate the occurrence of IFIS. A combination of strategies could decrease the complications of IFIS. These procedures include preoperative use of atropine, intracameral injection of dilute phenylephrine or epinephrine, the use of super-cohesive ophthalmic viscosurgical devices, lower phacoemulsification vacuum and aspiration settings and various iris hooks or pupil dilators.
