This document discusses signs, predisposing factors, timing, and management of a posterior capsule tear during cataract surgery. A posterior capsule tear can be identified by sudden pupil dilation, a falling away nucleus, or visible vitreous or capsule in the phaco tip. Risk factors include surgeon hand position, poor visibility from fluid, globe torsion, or underlying pathology. Tears often occur late in surgery during nucleus removal or capsule polishing. Management involves injecting viscoelastic to cover the tear and prevent vitreous prolapse, removing any lens fragments, and determining if an anterior or sulcus IOL placement is possible depending on tear size.
