PURPOSE: To report a series of cases involving Ahmed Glaucoma Valve M4 (AGV) explantation and to discuss the surgical technique to remove the drainage device. METHODS: Four cases were identified that presented with AGV M4 postoperative complications necessitating tube shunt removal. Three patients presented with conjunctival erosion and 1 patient with persistent diplopia. AGV M4 implants were removed successfully between 1.5 and 9 months after implantation. RESULTS: Successful explantation of the AGV M4 novel implant was achieved in all cases without intraoperative or postoperative complications. CONCLUSIONS: If necessary, AGV M4 explantation can be successfully performed in the early postoperative period.
