Abstract:AIM: To evaluate the efficiency and safety of 50g/L povidone-iodine solution in preventing postoperative endophthalmitis through comparing the incidence of postoperative endophthalmitis and adverse reactions after conjunctival sac washing with povidone-iodine of different concentrations.
METHODS: Totally 500 cataract patients were divided into 50g/L povidone-iodine group and 25g/L povidone-iodine group. All the operated eyes were observed during and after surgery.The patients' subjective discomfort was inquired and their signs of eyes were recorded.
RESULTS: The eye irritation of 50g/L povidone-iodine group was more significant than 25g/L povidone-iodine group. No significant difference in the corneal epithelial loss and endophthalmitis was observed between two groups.
CONCLUSION:Conjunctival sac washing with 50g/L povidone-iodine is an effective and safe measure to prevent endophthalmitis after cataract surgery.
