Intraoperative floppy iris syndrome: case report In a study of 5 patients with cataract, a patient [age and sex not stated] was described, who developed intraoperative floppy iris syndrome (IFIS) during treatment with dexmedetomidine as a sedative therapy. The patient, who had cataract, was scheduled to undergo cataract surgery. Subsequently, the patient was admitted and in the preoperative holding area the patient was administered with mydriatics cyclopentolate, phenylephrine and tropicamide. The pupils were found well dilated with the use of these mydriatics. The surgery was performed under unspecified topical anaesthesia and IV sedation with dexmedetomidine [dose not stated]. Within 5–10 minutes, the patient became constricted, suddenly quite and the iris became floppy. This clinical presentation was consistent with IFIS associated with dexmedetomidine. The patient was treated with epinephrine. However, the pupils were dilated to 3–4mm. Subsequently, suturing of the main corneal temoral incision was perfomed to prevent prolapsing of iris. The patient was also treated with unspecified topical steroids and the patient’s vision had recovered. Dersu I.
