Researchers are studying the trends in corneal transplantation procedures performed in Germany since 2001. This observational study aims to provide regular updates on the number of surgeries, the types of surgical techniques used, and the reasons for these corneal transplants. The German Ophthalmological Society's Section Cornea oversees this long-term registry to track and report these changes. The study involves all patients in Germany who have undergone various types of corneal transplantation procedures, including Penetrating Keratoplasty (PKP), Deep Anterior Lamellar Keratoplasty (DALK), Descemet Membrane Endothelial Keratoplasty (DMEK), and Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK). These procedures are observed and documented to understand evolving surgical practices and patient indications. Participants' data are collected continuously from 2001 through 2031, monitoring the absolute numbers of corneal transplants, the trends in different surgical types, and the medical reasons for transplantation. The registry provides interim assessments to keep current with the latest results, aiming for comprehensive long-term insight into corneal transplantation patterns in Germany.
