A half-strength povidone-iodine (Betadine) solution was used topically as part of the preoperative chemical preparation of the eye. Aerobic and anaerobic bacterial cultures of the conjunctiva were taken before and after the chemical preparation in 30 consecutive patients; the second eye served as a control. In the control eyes, no significant change in the number of colonies or species of bacteria was found. In the povidone-iodine-treated eyes, the numbers of colonies decreased 91% and the number of species decreased 50% (statistically significant). We therefore recommend that a half-strength povidone-iodine solution be used as part of the chemical preparation of the eye for surgery.
一种半强度聚维酮碘（碘伏）溶液被局部用于眼部术前化学准备。对30例连续患者在化学准备前后采集结膜的需氧和厌氧细菌培养样本；另一只眼作为对照。在对照眼中，细菌菌落数量或种类未发现显著变化。在聚维酮碘处理的眼中，菌落数量减少了91%，种类数量减少了50%（具有统计学意义）。因此，我们建议使用半强度聚维酮碘溶液作为眼部手术化学准备的一部分。
