The implantation procedure requires the surgeon to perform a dissection of the conjunctiva as well as the attached Tenon’s capsule (a) and then mark the end points of the scleral dissection on the sclera (b). This is necessary as the scleral dissection (c) must have a length of exactly 3.5 mm with little margin for error. Afterwards, the well perfused pars plana tissue underlying the sclera needs to be coagulated (d) to ensure that the following pars plana incision (e) does not result in vitreous hemorrhage. Finally, using a special implantation tool, the Port Delivery System implant is inserted (f) into the globe and released from the tool (g). In a final step, the conjunctiva and Tenon’s capsule are closed and sutured (h)
