Purpose of reviewEndothelial keratoplasty has evolved tremendously since its inception. Thick Descemet stripping automated endothelial keratoplasty (DSAEK) grafts have made sway for slimmer ultrathin Descemet stripping automated endothelial keratoplasty (UT-DSAEK). This review discusses the recent literature comparing outcomes of UT-DSAEK, DSAEK, and Descemet membrane endothelial keratoplasty (DMEK).Recent findingsDMEK provides quick visual recovery and has remarkably low incidence of graft rejection. However, the learning curve is long compared to DSAEK. UT-DSAEK utilizes donor grafts less than 100-μm thick. Recent studies comparing DMEK and UT-DSAEK have shown DMEK has better visual outcomes with similar rejection rates.SummaryUT-DSAEK remains an excellent surgical option for endothelial keratoplasty in eyes with complex anterior segment anatomy. The visual outcomes after UT-DSAEK have been shown to be superior when compared with DSAEK. Recent studies show that DMEK provides better visual outcomes compared with UT-DSAEK.
