title: Closed chamber pupilloplasty with an injectable shape memory alloy clip in enucleated porcine eyes in the laboratory setting.
abstract: A novel surgical technique and novel surgical instrumentation for closing a pupil defect in a closed chamber eye is described. The technique was performed in a laboratory setting using ex-vivo porcine eyes using a 30-gauge deployment system to repair iris defects. Given the difficulty of suturing in a closed chamber eye, the use of an injectable, shape memory alloy clip offers the advantages of rapid, easy deployment and increased strength over conventional suture techniques.
