Modified Wise closure of the conjunctival fornix-based trabeculectomy flap.

We present modifications to the Wise fornix-based conjunctival trabeculectomy flap technique that have minimized early wound leakage in our experience. A retrospective chart review of 509 consecutive eyes revealed a 2.9% leak rate in the first postoperative month and 1.6% returned to the operating room to resuture a persistent leak. If meticulously performed, this modified closure technique may provide watertight closure as commonly as limbal-based techniques.
