尽管后弹力层剥脱式自动内皮角膜移植术（DSAEK）已广泛作为治疗大泡性角膜病变的首选方法，但术中对供体内皮的机械应力引起的术后早期角膜内皮细胞丢失仍然是一个临床挑战。目前，牵拉技术是DSAEK中移植物输送的标准程序。然而，在亚洲患者中常见的小眼或浅前房患者中，前房可能在移植物输送过程中塌陷，导致内皮细胞损伤。为了解决这个问题，我们开发了一种新的DSAEK装置，称为NS Endo-Inserter，其中移植物在平衡盐溶液中一步流入前房。本文综述了NS Endo-Inserter的特点以及使用该器械进行DSAEK的结果。
Although Descemet stripping automated endothelial keratoplasty (DSAEK) has become widespread as a first choice for the treatment of bullous keratopathy, corneal endothelial cell loss during the early postoperative period caused by intraoperative mechanical stress to the donor endothelium remains a clinical challenge. At present, a pull-through technique is the standard procedure for graft delivery in DSAEK. However, the anterior chamber is likely to collapse during graft delivery in patients with a small eye or shallow anterior chamber, as often seen in Asian patients, leading to endothelial cell damage. To solve this problem, we developed a new device for DSAEK, known as NS Endo-Inserter, in which the graft flows into the anterior chamber in a balanced salt solution in one step. This article reviews the features of NS Endo-Inserter and the outcomes of DSAEK using this device.
