A cluster of symptoms and signs that appear to be related to wound closure developed in 10 of 105 consecutive patients (9.5%) who underwent uncomplicated planned extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PC IOL) implants. These signs and symptoms included foreign body sensation, conjunctival injection and infiltrates localized to the scleral wound, and scleral excavation underlying the running 10-0 nylon suture possibly resulting from localized scleral edema. The clinical presentation ranged from 1 to 6 weeks. Conjunctival stains demonstrated eosinophils and polymorphonuclear leukocytes in some cases. Gram stains, conjunctival cultures, and results of suture toxicology studies were negative. The authors believe that these findings represent a previously unreported complication after ECCE: acute inflammation primarily localized to the conjunctiva and sclera adjacent to the cataract wound. The etiology of this postoperative complication is yet to be determined.
在105例连续接受无并发症计划性囊外白内障摘除术（ECCE）并植入后房型人工晶状体（PC IOL）的患者中，有10例（9.5%）出现了一组似乎与伤口闭合相关的症状和体征。这些症状和体征包括异物感、结膜充血以及局限于巩膜伤口处的浸润，还有在连续的10-0尼龙缝线下方出现的巩膜凹陷，这可能是由局限性巩膜水肿所致。临床表现持续时间为1至6周。结膜染色显示在某些病例中有嗜酸性粒细胞和多形核白细胞。革兰氏染色、结膜培养以及缝线毒理学研究结果均为阴性。作者认为这些发现代表了ECCE术后一种此前未报道过的并发症：急性炎症主要局限于白内障伤口附近的结膜和巩膜。这种术后并发症的病因尚待确定。
