PURPOSE: To describe a mechanism for wound incompetence after phacoemulsification with corneal incisions resulting in early postoperative wound leakage.
DESIGN: Observational case series.
METHODS: Three patients who had uneventful phacoemulsification through a clear corneal incision were identified because of a postoperative wound leak. A corneal tongue, consisting of an everted triangular flap of posterior corneal stroma, the Descemet membrane, and endothelium, was observed in the wounds of all cases.
RESULTS: One wound leak resolved after pressure patching. The other two necessitated wound revisions. None of the patients developed endophthalmitis.
CONCLUSIONS: In phacoemulsification with corneal incisions, an everted flap of posterior corneal tissue, a corneal tongue, may prevent normal anatomical apposition of the surgical wound edges leading to potential wound incompetence. This event may increase the risk of endophthalmitis after clear corneal phacoemulsification.
