目的　总结白内障超声乳化术中囊膜阻滞综合征的诊治经验。方法　 1997年 6月～ 2 0 0 0年 6月 3a内 12 5 2例白内障患者行超声乳化联合后房型人工晶状体植入术 ,发现 5例患者 (5眼 )在行环行撕囊、水分离后眼压突然升高、前房变浅、虹膜前移、晶状体核与环行撕囊后的前囊膜紧贴。其中初始 1例发生晶状体后囊破裂、晶状体核坠入玻璃体腔 ,对此 1例进行玻璃体切割联合巩膜缝线固定后房型人工晶状体植入术。之后 4例用冲洗针头轻轻地拨动晶状体核 ,使前房与晶状体核后空间沟通 ,眼压下降 ,并顺利完成超声乳化联合后房型人工晶状体植入术。结果　患者经术中处理后眼压均恢复正常。术后 1周视力达 0 .5～ 0 .7。结论　囊膜阻滞综合征是与环行撕囊相关的一种并发症 ,对此并发症的认识将有助于采取恰当的术中防治措施 Objective To summarize the diagnosis and treatment of capsular block syndrome in phacoemulsification. Methods A total of 125 cases of cataract patients from June 1997 to June 2003 were treated with phacoemulsification and posterior chamber intraocular lens implantation. Five patients (5 eyes) underwent circumferential capsulorhexis and water separation Intraocular pressure suddenly increased, shallow anterior chamber, iris forward, the nucleus and the anterior capsulorhexis after the anterior capsule close. Among them, the first case had a posterior capsule rupture and the nucleus of the lens crashed into the vitreous cavity. In this case, vitrectomy combined with scleral suture fixation and posterior chamber intraocular lens implantation was performed. After 4 cases with a needle gently dial lens nucleus, the anterior chamber communicating with the lens nuclear space, intraocular pressure drop, and the successful completion of phacoemulsification and posterior chamber intraocular lens implantation. Results The intraocular pressure returned to normal after intraoperative treatment. Visual acuity reached 0.5 ~ 0.7 after 1 week. Conclusions Blockade syndrome is a complication associated with atrial capsulorhexis, and awareness of this complication will help to provide appropriate intraoperative prevention and control measures
