AIM: To evaluate the sterilizing effects of 50g/L povidone Iodine used in conjunctival sag before cataract surgery.<p>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.<p>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. <p>CONCLUSION: The application effect of 50g/L povidone iodine in killing conjunctival sac bacteria is remarkable, which can avoid the postoperative endophthalmitis effectively.
