ATM: To analyze the result of bacterial culture and antibiotics sensitivity tests in conjunctival sacs of cataract patients in China before operation, so as to provide theoretical evidence for aseptic preparation of cataract surgery.

METHODS: Database including the VIP Database for Chinese Technical periodicals, Wanfang database, CNKI and CBM Disc were searched to collect the relevant articles about bacterial culture and antibiotics sensitivity tests in conjunctival sacs of cataract patients in China before operation. The relative factors were analyzed by Meta-analysis.

RESULTS: A total of 7 reports with 11499 eyes were selected. The number of positive specimens of bacterial culture in non-infectious cataract patients before operation was 2993(26.03%)from 11499 specimens G⁺ C(86.40%), G⁺ B(8.10%), G^-B(4.13%)and G^-C(1.37%)constituted predominant bacteria in the conjunctive sac of cataract patients in China before operation, mainly staphylococcous epidermidis(67.30%), staphylococcous aureus(12.53%)and micrococcus(6.98%). Most of them were susceptible to tobramycin, vancocin, ciprofloxacin and gentamycin, and improved the tolerance of tobramycin and ciprofloxacin.

CONCLUSION: Staphylococcous epidermidis is the most frequent bacteria isolated in the conjunctival sac of eyes before cataract surgery. Most of themare susceptible to tobramycin, vancocin, ciprofloxacin and gentamycin, and improve the tolerance of tobramycin and ciprofloxacin.
