Applications for a corneal mattress suture in anterior limbal wound repairs

We describe the use of a corneal mattress suture to manage two complications of trabeculectomy: first, to repair an anterior conjunctival tear/disinsertion in a limbus-based conjunctival flap; and, second, to restore wound integrity by reinforcing a focal section of scleromalacia or to close a perforation remaining from a previous cataract wound encountered during complicated trabeculectomy. In each setting, a single, double-armed 10-0 nylon corneal mattress suture is used as an anchor to establish a watertight limbal-wound closure. Additionally, for repairing an area of a scleromalacia/perforation, the corneal mattress suture can be used to incorporate a graft of Tenon's fascia into the wound.
