摘要近年来在欧美国家角膜内皮移植术(EK)已经逐步取代穿透性角膜移植术(PKP),成为治疗角膜内皮功能失代偿的主要手术方法.该手术安全、有效,术后视觉效果好.随着显微技术的提高及手术器械的不断改进,EK术式不断创新,术后临床效果不断优化.目前临床应用的EK术式主要包括剥离后弹力层EK、剥离后弹力层自动EK、后弹力层EK及超薄植片-自动角膜刀剥离型后弹力层EK等.与传统PKP比较,EK的各种术式在保留原有手术效果的基础上,均具备各自不同的特点和优势.本文针对EK不同术式的特点、临床效果及相关并发症的研究进展进行综述,以期为临床工作提供参考.

abstractsEndothelial keratoplasty (EK) has gradually replaced penetrating keratoplasty (PKP) and has become the main method for the treatment of endothelial dysfunction in developed countries in recent years.EK is safe and effective and can achieve good postoperative vision.The surgical techniques and postoperative effects have been improved continuously along with the development of microsurgical technology and surgical instruments.The EK surgeries mainly include Descemet stripping endothelial keratoplasty (DSEK),Descemet stripping automated endothelial keratoplasty (DSAEK),Descemet membrane endothelial keratoplasty (DMEK) and ultra-thin Descemet stripping automated endothelial keratoplasty (UT-DSAEK),which have different characteristics and advantages compared with PKP.In this article,the characteristics of different EK surgeries,postoperative effects and related complications in clinical research are reviewed.
