Abstract

Intraoperative Floppy iris syndrome(IFIS) remains a challenge for surgeons during phacoemulsification. Initially, it was related to the use of tamsulosin, an alpha adrenergic receptor blocker used in benign prostatic hyperplasia. Subsequently, other alpha adrenergic receptor such as alfuzosin, terazosin and doxazosin alongwith different other class of medications and systemic risk factors were identified. Other class of medications includes 5-alpha reductase inhibitor, angiotensin receptor antagonist, benzodiazepines, antipsychotics and antidepressants. Other risk factors include increasing age, male gender, diabetes, hypertension and decreased preoperative pupil diameter. It is very important for surgeons to identify these risk factors preoperatively and take appropriate preoperative and intraoperative measures to tackle the dreaded complications of IFIS. Sometimes, it is important for an ophthalmologist to work in cooperation with physician and urologist to minimize the complications. In conclusion, awareness of the risk factors associated with IFIS, their detailed preoperative assessment and intraoperative measures and surgical intervention is crucial in addressing IFIS. Lack of awareness can turn a routine, uneventful surgery into one with significant visual morbidity.
