Summary: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.
