We present a technique to achieve ultrathin Descemet-stripping automated endothelial keratoplasty (DSAEK). Using a simple method of controlling artificial anterior chamber pressure and drying the corneal surface, it was possible to thin the donor cornea at a rate of 11 μm a minute. When the donor cornea was between 500 μm and 510 μm, a single pass was made using a 350 μm microkeratome head followed by a peripheral dissection. The resulting mean graft thickness was 83.2 μm ± 14.9 (SD) (range 50 to 98 μm) with a mean peripheral graft edge thickness of 106...

PURPOSE: Although the functional results following DMEK are better than after DSAEK, DSAEK still seems to be the standard procedure, as surgeons fear losing grafts during DMEK graft preparation. Therefore, eye banks offer precut DMEK grafts for direct use by the surgeon. Here, we analysed the functional results and complication rates for a precut technique compared to fresh preparations. METHODS: We retrospectively compared 453 standard to 11 precut (1-2 days before surgery) DMEK cases...
