RESUMEN
Objective To analyze the therapeutic effect of povidone iodine diluent conjunctival sac combined with levofloxacin eye drops on cataract surgery to provide a basis for clinical treatment. Methods 400 patients with cataract surgery were enrolled in our hospital from January 2017 to June 2017. They were divided into two groups according to the random number table (n=200, 312 eyes) and the combined treatment group (n= 200, 325 eyes). In the conventional treatment group, levofloxacin was used to prevent postoperative infection. The combined treatment group was treated with povidone iodine dilution on the basis of conventional treatment group to prevent postoperative infection , Compared with the two groups of patients before surgery, postoperative, 2d postoperative bacterial culture and adverse reactions occurred. Results The positive rate of bacterial culture was 0.62％ on the 2nd day in the combined treatment group and 5.77％ in the conventional treatment group (P<0.05). The incidence of adverse reaction was 0.92％ in the combined treatment group and the conventional treatment group The incidence of reaction was 2.88％ (P<0.05). Conclusion The effect of povidone iodine diluent conjunctival sac rinse combined with levofloxacin eye drops on the prevention of cataract surgery is very good, which can greatly reduce the positive rate of bacterial culture and reduce the incidence of adverse reactions in patients.
