Objective: To report the initial experiences with the 25-gauge transconjunctival sutureless vitrectomy (TSV) system, including intraoperative and postoperative problems. Methods: We retrospectively reviewed the medical records and surgical videotapes of 50 consecutive patients who underwent vitrectomy performed by one surgeon using the TSV system. Results: Intraoperatively, we encountered such problems as difficulty in inserting the microcannula, which led to deformity, instability of the microcannula, self-disconnection of the infusion tip and resultant lens damage, and conversion to 20-gauge conventional vitrectomy. Postoperatively, there were 8 cases with hypotony (IOP < 6 mm Hg) on day 1, 6 cases with elevated IOP, and 3 cases with retinal detachment during follow-up. Conclusion: Though certain problems exist during and after surgeries using TSV, this system is both convenient and safe for various vitreoretinal procedures.
