title: Management of lens-iris diaphragm retropulsion syndrome during phacoemulsification.
abstract: Lens-iris diaphragm retropulsion syndrome (LIDRS) occurs more often than recognized during small-incision phacoemulsification. This syndrome requires an infusion of fluid into the anterior chamber and is characterized by posterior displacement of the lens-iris diaphragm, marked deepening of the anterior chamber, posterior iris bowing, pupil dilation, and often significant patient discomfort. Using microendoscopy, we have observed that LIDRS is essentially a reverse pupillary block. We describe a surgical technique to mechanically break the iridocapsular block to restore normal chamber depth, relieve patient discomfort, and allow the surgeon to proceed safely with phacoemulsification.
