AIM:To systematic evaluate the preventive effect of non-steroidal anti-inflammatory drugs(NSAIDs)on the cystoid macular edema(CME)after the cataract surgery.

METHODS:Searching literature which were published by March 2015 and which were the random control test(RCT)on the preventive effect of NSAIDs on CME after the cataract surgery in PubMed, EMbase, Cochrane Library, MEDLINE, CNKI, Wanfang Data, Chongqing Weipu and Chinese biomedical literature database and through Internet with computer. Meanwhile, relevant articles, journals, conference papers and their reference were manually retrieved. According to inclusion and exclusion criteria,the study objects were limited.Revman5.0 software provided by the Cochrane Collaboration was used to analysis the incidence of CME after cataract surgeries.

RESULTS:A total of 7 RCT were included in the study(1422 cases, 712 cases in the trial group, 710 cases in the control group). Using NSAIDs before and after cataract surgeries could significantly reduce the post-operative incidence of CME(OR=0.31, 95%CI:0.18～0.52, P<0.001).

CONCLUSION:Using NSAIDs before and after cataract surgeries can significantly reduce the incidence of postoperative CME. Due to the small sample size and the medium methodological quality, the conclusion is not powerful enough. More high-quality RCTs with larger sample size are needed to make the evaluation more objective, accurate and comprehensive.
