Illustrations of the graft-repositioning technique using an infusion cannula (A, E) Before repositioning, the DMEK graft is dislocated to the upper right side. B, F The infusion cannula is inserted into the anterior chamber, and the infusion switch is turned on and off several times. The anterior chamber deepens, and the graft detaches from the posterior surface of the cornea through aqueous flow, with the air bubble smaller than the graft. C, G The eye is tilted in the displaced direction, and a blunt needle is stroked from the sclera to the center of the cornea. D, H After performing the repositioning technique, the graft moves to the center. As with conventional DMEK, the anterior chamber is replaced with gas or air, and the grafts are attached DMEK, Descemet’s membrane endothelial keratoplasty
