Problems associated with the 25-gauge transconjunctival sutureless vitrectomy system during and after surgery.
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.


CONCLUSIONS
Though certain problems exist during and after surgeries using TSV, this system is both convenient and safe for various vitreoretinal procedures.
