白内障手术用不用抗菌素作预防性治疗,用何种抗菌素,以及何时(术前、术中、术后)应用,一向是有争论的。为此,著者将其一千余例白内障摘出手术分为二组,进行观察比较。第一组,术前一周用磺胺醋酰点眼或用氯霉素及多粘菌素的混合液点眼,每日三次,并于手术结束时结膜下注射青霉素及链霉素。第二组,术前术后均不用抗菌素治疗。两组均作术前培养。第一组 Cataract surgery has been controversial without the use of antibiotics as prophylactic treatment, with which antibiotics, and when (preoperative, intraoperative, postoperative) applications.
