DMEK: the Grand Prix of cornea transplant surgery

Descemet membrane endothelial keratoplasty (DMEK) is the most recent iteration of endothelial keratoplasty. With DMEK, restoration of true corneal anatomy is achieved. The majority of outcomes of DMEK surpass those of any of its predecessors - visual acuity, speed of recovery, refractive shift and stability as well as immunologic rejection are all better than before. As surgical techniques are continuously being refined, so endothelial cell densities and complications rates are steadily improving. All of these account for DMEK gaining popularity with corneal surgeons as well as patients suffering from corneal endothelial disease. This review highlights the recent advances in this exciting field of corneal surgery and addresses current challenges and contentious issues.
