Abstract #49188 Published in IGR 14-1
Fixation of External Drainage Device With Injectable Shape-memory Alloy Clips
Olson JL; Erlanger MJournal of Glaucoma 2013; 22: 569-571
PURPOSE: To describe a novel surgical technique and novel surgical instrumentation for fixating an extraocular drainage device used for glaucoma-filtering surgery. MATERIALS AND METHODS: The technique was performed in a laboratory setting using ex-vivo porcine eyes. We describe the surgical technique of using injectable, 25-gauge shape-memory clip system to fixate an Ahmed drainage device. RESULTS: The use of an injectable, shape-memory alloy clip provides the advantages of rapid, easy deployment and decreased risk of late suture failure. Importantly, the injectable, shape-memory clips can be used in surgical situations where suturing is difficult and time intensive, such as those encountered during glaucoma drainage device placement. CONCLUSIONS: The use of an injectable, shape-memory alloy clip is a promising new surgical tool and technique for fixating an extraocular drainage device used for glaucoma surgery.
