[Problems deserving attention in preventing infection in cataract surgery].

Endophthalmitis is one of the most serious complications of cataract surgery. The surgeons try to reduce the incidence of endophthalmitis. In order to prevent postoperative infection, irrigation of the conjunctival sac with povidone iodine and injection of antibiotics into the anterior chamber before the end of the surgery are used. Although there are a lot of reports about the concentration, mode and duration of povidone iodine application, there is no consensus. There are many options for antibiotics, including cefuroxime, vancomycin and moxifloxacin. Side effects of using povidone iodine and antibiotics have also been reported. An aseptic surgical mask plays an important role in isolating bacteria for prevention of infection. However, whether it could completely isolate bacteria can not be determined. In this article, several issues concerning the prevention of infection after cataract surgery are discussed. We hope that there will be a multi-center and large-sample research to assist in drawing up operating specifications. (Chin J Ophthalmol, 2017, 53: 805-809).
