Surgically acquired foreign body is a serious complication of microscopic surgery.1 In fornix-based trabeculectomy with mitomycin C, sponges soaked with mitomycin C are placed under the conjunctival flap for 3–5 min, after which the sponges are removed with a toothed forceps. Sponges may be lost under the conjunctival flap because in fornix-based trabeculectomy, the sponges are inserted deep into the conjunctival–scleral interface. Numerous complications due to retained cellulose sponges after trabeculectomy with mitomycin C such as granulomas or conjunctival hole formation have already been reported.2 3

We used DELICOT (Cat# 63-01, American Surgical Sponges, Lynn, Massachusetts; figure 1) as a device to deliver mitomycin C to the sclera during trabeculectomy.
