摘要

这项工作的目的是提出一种新的技术,安全有效地获得移植物的Descemet膜内皮角膜移植术(DMEK),由于其快速的学习曲线和降低移植物撕裂的风险。该技术涉及到内皮细胞的周围剥离,首先使用30号针在角膜周围360度的施瓦尔贝线内1毫米处做一个浅表切口。然后应用台盼蓝显示解剖边界,并使用DMEK Sinskey钩沿整个周长提起1mm外周移植物。该技术继续将Descemet的膜从基质中分离出来,这是通常的做法。与其他技术相比,该技术通过使用标准针头降低了成本,故障率低。

30-Gauge Needle Descemet Membrane Endothelial Keratoplasty Graft Obtention: A novel, safer and cheap technique.

This work aims to present a novel technique for obtaining grafts for Descemet Membrane Endothelial Keratoplasty (DMEK) safely and efficiently, thanks to its fast learning curve and reduced risk of graft tears. The technique involves the peripheral dissection of the endothelium starting with a superficial incision made using a 30-Gauge needle, 1 mm inside Schwalbe's line across 360º of the corneal periphery. Trypan Blue is then applied to visualize the dissection boundary, and a DMEK Sinskey hook is used to lift 1 mm of the peripheral graft along the entire circumference. The technique continues with the separation of Descemet's membrane from the stroma, as is commonly performed. This technique reduces costs by employing a standard needle and achieves low failure rates compared to other techniques.
