Effect of domestic povidone iodine on conjunctival sac disinfection.

OBJECTIVE To analyze the effect on disinfecting conjunctival sac by 1% domestic povidone iodine.METHODS A total of 200 patients(200 eyes) receiving intraocular surgery were randomly and equally divided into 2 groups(group A and group B).1% Domestic povidone iodine solution was used to irrigate the conjunctival sac before intraocular surgery in group A while 0.8% gentamicin solution was used in group B.Conjunctival cultures were obtained before and after the conjunctival sac was irrigated.RESULTS Before the conjunctival sac was irrigated,the positive rates of conjunctival cultures were 33% in group A and 32% in group B vs 2% in group A and 11% in group B after irrigation.CONCLUSION Irrigating the conjunctival sac with 1% domestic povidone iodine solution before operation is more effective in reducing the rate of contamination than with 0.8% gentamicin solution.Irrigating the conjunctival sac with 1% domestic povidone iodine solution is a good measure to prevent postoperative endophthalmitis.
