Preoperative Preparation of Eye with Chlorhexidine Solution Significantly Reduces Bacterial Load Prior to 23-Gauge Vitrectomy in Swedish Health Care

Bacteria in the conjunctiva present a potential risk of vitreous cavity infection during 23-gauge pars plana vitrectomy (PPV). Current preoperative procedures used in Sweden include irrigation with chlorhexidine solution (CHX) 0.05% only and no iodine solutions. We evaluated the bacterial diversity and load before and after this single antibacterial measure.
