An der Klinik f\u00fcr Augenheilkunde, Universit\u00e4tsklinikum des Saarlandes UKS in Homburg\/Saar, kamen Systeme von Zeiss und Schwind zum Einsatz, die wir in dieser Studie bez\u00fcglich der postoperativen Ergebnisse verglichen haben.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Patienten und Methoden<\/jats:title>\n                <jats:p>In die retrospektive Studie eingeschlossen wurden Patienten, die im Zeitraum 2007 bis 2017 mit der Diagnose MDF mittels PTK behandelt wurden. Es erfolgten 170 Operationen mittels des Lasersystems Zeiss Meditec MEL-70 (Carl Zeiss Meditec AG, Jena, Deutschland) und 98\u00a0mittels Schwind eye-tech-solutions Amaris 750S (Schwind eye-tech-solutions GmbH, Kleinostheim, Deutschland). Erhoben wurden pr\u00e4- und postoperative Werte zu Visus, Refraktion, Astigmatismus sowie Kr\u00fcmmungsdaten aus der Pentacam und Endothelzellcount.

Zu signifikanten Ver\u00e4nderungen des sph\u00e4rischen \u00c4quivalents kam es weder im pr\u00e4-\/postoperativen Vergleich noch zwischen den Lasergruppen.
