摘　　要：目的探讨人工晶状体术后早期囊袋阻滞综合征(capsularblock syndrome,CBS)的临床表现、发生机制、治疗和预防方法。方法收集超声乳化、人工晶状体囊袋内植入术后早期出现CBS者13例(13眼)。首先尝试Nd:YAG激光周边前囊切开术;其中1例瞳孔不能散大无法暴露周边前囊,则改行激光后囊切开术。结果13例CBS均表现出明显的撕囊口阻滞、囊袋高度扩张、人工晶状体前移位、浅前房和近视性漂移。除1例未经干预自行消失外,其余12例经Nd:YAG激光囊切开后CBS消失,前房深度平均加深(1.52±0.67)mm。结论囊袋内黏弹剂残存是造成术后早期CBS的重要因素。激光周边前囊切开术、后囊切开术可安全、有效地治疗CBS。Objective To explore the clinical characteristics,the etiology, the regimen and the prevention of early postoperative capsular block syndrome （CBS）. Methods 13 patients （13 eyes） with early postoperative CBS after phacoemulsification and in -the - bag implantation of a intraocular lens （IOL） were includ- ed in the study. Postoperative CBS was relieved by performing an anterior capsulotomy peripheral to the edge of the IOL first, if ob- servable, or a posterior capsulotomy if the pupil cannot be dilated to the edge of the IOL. Results Early postoperative CBS was characterized by occlusion of continuous curvilinear capsulorhexis, capsular hyperexpansion, IOL displacement anteriorly, anterior chamber shallowing, and an unexpected postoperative myopic shift. The CBS spontaneously resolved without intervention in 1 patient. The CBS was relieved by performing a laser capsulotomy in the oth- er 12 patients and the anterior chamber was deepened by 1.52±0.67 mm on an average. Conclusions Viscoelastic material re- tained in the capsular bag plays an important role in the develop- ment of early postoperative CBS. Laser peripheral anterior and pos- terior capsulotomies are effective and safe options.
