Clinical application of 25 G transconjunctival sutureless vitrectomy system / 中华眼底病杂志

ABSTRACT

Objective To evaluate the practicability and safety of 25-gauge (25G) transconjunctival sutureless vitrectomy system (TSV25G) and describe the preliminary experience. Methods Eighteen patients underwent TSV25G. The time of procedures of setting-up the three-port cannulae and closing the cuts were recorded. The pre- and post-operative ocular tension, visual acuity and complications were observed. Results The average time of setting-up the three-port cannulae and closing the cuts was 1 minutes 24 seconds and 32 seconds, respectively. The average preoperative ocular tension was 16.3 mm Hg(1 mm Hg=0.133 kPa); the average postoperative ocular tension at the first day, first week, and first month was 13.0, 15.9, and 16.4 mm Hg, respectively. The visual acuity before and one month after operation the was HM/20 cm～0.2 and HM/50 cm～0.6, respectively. No postoperative complication was found. Conclusion TSV25G may simplify the operation, minimize the surgical induced trauma, and decrease the operating time and the postoperative inflammatory response.
