Surgical Instrument Contamination in 25-Gauge Vitrectomy Cases

From December 2023 to February 2024, a retrospective analysis of 96 eyes from 86 immunocompetent patients who underwent 25-gauge pars plana vitrectomy was conducted. The dataset, authored by Fumiya Miyako and shared on figshare, evaluates the incidence of surgical instrument contamination. It reports contamination in 7 cases (7.3%) and the association of preoperative antibacterial eye drops with lower contamination risk.

Use Cases

• Assessing contamination rates in microincision vitrectomy surgery based on the reported 7.3% incidence.
• Evaluating the association between preoperative antibacterial eye drops and contamination risk as described in the results.
• Analyzing the distribution of bacterial species isolated from specific instruments like the trocar, endoilluminator, and beveled probe.
• Studying postoperative outcomes like endophthalmitis incidence during a 2-month follow-up period.

Strengths

• The dataset is based on a specific cohort of 96 eyes from 86 patients.
• It provides a clear contamination rate of 7.3% (7 cases).
• It includes a defined 2-month follow-up period for tracking postoperative endophthalmitis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (9.5 KB), indicating limited scope.
