Residual Anterior Chamber Nuclear Mass after Phacoemulsification: A Case Report

晶状体核块或晶状体碎片残留常发生于白内障超声乳化术中出现后囊破裂的患者中；手术中顺利，无后囊破裂的患者中，术后晶状体核块残留发生很少。术后残留晶状体核块可以继发眼压升高、角膜水肿、葡萄膜炎和其它并发症，这种并发症可能导致视功能障碍。本文报道一例Ⅳ级硬核年龄相关性白内障患者，白内障超声乳化及人工晶状体植入手术过程顺利，术中没有发生后囊破裂等并发症的患者，术后1周发现前房晶状体核块残留，导致角膜水肿，经二次手术行前房冲洗术取出残留晶状体核块，术后恢复良好。 Residual lens nucleus or lens fragments often occur in patients with posterior capsule rupture during phacoemulsification, but rarely in patients without posterior capsule rupture. Intraocular pressure, corneal edema, uveitis and other complications can be secondary to residual lens nucleus after surgery, which may lead to visual dysfunction. This paper reported a case of age-related cataract with grade IV hard nucleus. Phacoemulsification and intraocular lens implantation was successfully performed. Posterior capsule rupture didn’t occur during the operation. One week after the operation, a residual lens nucleus was found in the anterior chamber, which led to corneal edema. The residual lens nucleus was removed by anterior chamber irrigation and recovered well.
