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.
