摘　　要：目的:评价50g/L聚维酮碘溶液对降低白内障术前结膜囊病原菌的有效性。方法:选择行白内障超声乳化联合人工晶状体植入术的患者45例58眼,选取术眼在入院时,点用加替沙星眼液后及使用聚维酮碘结膜囊消毒后三个时间点,取结膜囊拭子送检进行细菌培养。结果:入院时,点用加替沙星滴眼液后及50g/L聚维酮碘点眼消毒后细菌培养的阳性率分别为:79.3%,41.9%,3.4%,培养阳性率明显逐渐降低。结论:眼科临床所用消毒剂50g/L聚维酮碘术前点眼消毒可有效抑制结膜囊细菌,避免术后眼内炎的发生。AIM： To evaluate the sterilizing effects of 50g/L povidone Iodine used in conjunctival sag before cataract surgery. METHODS： Totally, 58 eyes of 45 cataract patients underwent phacoemulsification aspiration with intraocular lens implantation.The cojunctival sac secretions at three time points （ admission, before and after disinfection with povidone iodine） were obtained and then cultured under the same condition and at the same time.The results were observed and identified. RESULTS： At the three points, the positive rate of bacterial culture was 79.3%, 41.9% and 3.4%, respectively. The positive rate significantly reduced gradually. CONCLUSION：The application effect of 50g/L povidone iodine in killing conjunctival sac bacteria is remarkable, which can avoid the postoperative endophthalmitis effectively.
