Abstract
To evaluate the incidence of surgical instrument contamination associated with microincision vitrectomy surgery. Ninety-six eyes from 86 immunocompetent patients who underwent 25-gauge pars plana vitrectomy from December 2023 to February 2024 in our institution were retrospectively analyzed. Surgical instrument contamination was detected in 7 cases (7.3%). Bacterial species were isolated from the trocar, endoilluminator, and beveled probe. Postoperative endophthalmitis did not occur during the 2-month follow-up period. Use of preoperative antibacterial eye drops was significantly associated with lower risk of bacterial contamination. Contamination may occur 25-gauge pars plana vitrectomy, even when preoperative antibacterial eye drops are used in conjunction with povidone-iodine irrigation and adequate vitreous dissection.
