Abstract:

Intraoperative floppy iris syndrome (IFIS) occurs in 2% of cataract surgeries. Its occurrence is mainly related to the application of alpha 1 adrenergic receptor antagonist and some antihypertensive medications, and the genenal condition such as hypertension may also participate in it. In response to these already known risk factors, IFIS cases with iris floppy, progressive pupil reduction and self prolapsing from the surgical incisions, the combined application of a variety of techniques and treatments, as alpha 1 adrenergic activator, viscoelastic agent, iris retractor, pupil dilator and so on, would greatly reduce the related complications.
