糖尿病性白内障患者超声乳化术后角膜水肿相关因素

摘要

白内障是眼科首位致盲性眼病.近些年,超声乳化术因为其时间短、损伤小的特点逐渐成为治疗白内障的首选方法,被眼科医生普遍采用.随着技术的不断提高,超声乳化术所造成的严重并发症越来越少,但术后并发角膜水肿细胞密度的危险阈值是1000个/mm2,当细胞密度低于阈值时,角膜水肿的发生率成倍增长.角膜水肿的现象并不罕见,尤其是在糖尿病性白内障患者中,角膜水肿的发病率更高.现就角膜水肿的概念、发病机制及糖尿病性白内障患者超声乳化术后角膜水肿的相关因素做一综述.%Cataract is the first ophthalmological blinding eye disease. In recent years, phacoemulsification has become the preferred method for the treatment of cataract due to its short time and small damage, which is widely used by ophthalmologists. With the continuous improvement of technology, serious complications caused by phacoemulsification become less and less. But the phenomenon of postoperative corneal edema is not uncommon. The incidence of corneal edema is especially high in patients with diabetic cataracts. This paper reviewes the concept of corneal edema, pathogenesis and the related factors of corneal edema after phacoemulsification in diabetic cataract patients.
