9A94.1

ICD-11 MMS 2026-01

Floppy iris syndrome

Description

This is a complication that may occur during cataract extraction in certain patients. This syndrome is characterised by a flaccid iris which billows in response to ordinary intraocular fluid currents, a propensity for this floppy iris to prolapse towards the area of cataract extraction during surgery, and progressive intraoperative pupil constriction despite standard procedures to prevent this.
