PURPOSE: To introduce a new non-trocar system for 25-gauge transconjunctival pars plana vitrectomy (PPV).
DESIGN: Study of a new surgical instrument.
METHODS: This new non-trocar system for 25-gauge transconjunctival PPV consists of a contact lens ring featuring four projections containing 1.0-mm diameter holes located 3.0 mm from the ring edge, a wedge-shaped 25-gauge infusion cannula, and two plugs.
RESULTS: The ring is fixed with 7-0 silk sutures at the 3- and 9-o'clock positions on the limbus. Using the 25-gauge needle, three conjunctival and scleral incisions (n = 3) are made at the projection holes located inferotemporally, superonasally, and superotemporally. No intra- or postoperative complications were encountered in 14 patients treated by this non-trocar 25-gauge transconjunctival PPV.
CONCLUSION: Using the system introduced here, 25-gauge transconjunctival PPV can be performed without suturing sclerotomies and without intra- or postoperative complications.
