Effect of different residence time of povidone iodine on the disinfection effect of conjunctival sac in senile cataract surgery
摘要
Abstract
Objective To investigate the effect of different residence time of povidone iodine on the disinfection effect of conjunctival sac in senile cataract surgery.Methods A total of 396 senile patients who underwent cataract surgery in our hospital were selected and randomly divided into the long-residence group and the short-residence group,with 198 cases in each group.The patients of the long-residence group and the short-residence group were disinfected with a disposable filling 5%povidone iodine on conjunctival sac for 3 minutes and 30 seconds before surgery,respectively.The bacterial detection and bacterial distribution on conjunctival sac,and corneal epithelial cell damage were compared between the two groups.The subjective comfort conditions such as ocular itching,foreign body sensation,erythema,and photophobia after disinfection were recorded.Results There was no significant difference in the bacterial detection rate before and after disinfection between the two groups(P>0.05).The most frequently detected bacteria in the short-residence group was Staphylococcus epidermidis,accounting for 28.79%and 33.33%before and after disinfection,respectively.The incidences of ocular itching,foreign body sensation,erythema,and photophobia after disinfection in the short-residence group were significantly lower than those in the long-residence group(P<0.05),while the rate of corneal epithelial cell damage in the long-residence group was significantly higher than that in the short-residence group(P<0.05).Conclusion The use of disposable filling 5%povidone iodine for disinfection on conjunctival sac for 30 seconds before surgery can achieve a comparable disinfection effect to disinfection for 3 minutes,which has less effect on corneal epithelial cells,and higher ocular comfort.关键词
