Vergleich der sterilen Spendertomographie in der Hornhautbank mit der Tomographie des Transplantates nach perforierender Keratoplastik

Abstract: Zusammenfassung Hintergrund Seit 2018 verwenden wir die sterile Spendertomographie in der Hornhautbank routinemäßig, um refraktive Überraschungen nach Keratoplastik zu vermeiden. Ziel dieser Studie war es, Spendertomographieparameter mit Tomographieparametern des Transplantates nach perforierender Keratoplastik (PKP) zu vergleichen. Methoden Diese Studie umfasste 193 Spendergewebe der Hornhautbank, die für eine PKP verwendet wurden (Transplantatdurchmesser 8,2 ± 0,7 mm). Messungen wurden mit dem optischen Koh… Show more

“…The method lasts about 12 minutes -2 minutes for measurement and 10 minutes for evaluation. In the future, sterile donor tomography could enable: (1) the harmonisation of donor and recipient tomography [23,24], poten-tially minimising persistent residual astigmatism after suture removal for a particular donor-recipient pair; and (2) the improvement of the IOL power calculation in a classical triple procedure by means of regression analysis between pre-and postoperative total refractive power of donor corneal tissues [25]. These projects are currently being researched in Homburg/Saar.…”

“…It measures 5 μm in thickness and is formed by single-layered hexagonal endothelial cells. This layer plays a critical role in keeping the cornea clear and transparent by pumping out water from the cells through an active transport system of electrolytes and liquids [29,65]. Through a membrane-bound Na + -K + -ATPases, the endothelium regulates the outflow of the aqueous humour from the stroma and provides a barrier function between the anterior chamber of the eye and the cornea [11].…”
