In dieser Arbeit wird ein neuer Bildverarbeitungsalgorithmus zur Verbesserung der Qualit\u00e4t\n\t\t\t\t\tsolcher generierten axialen Querschnittsbilder vorgestellt und beide Methoden werden miteinander verglichen.<\/jats:p><jats:p>\n          Material und Methoden Die 3-dimensionale Punktspreizfunktion einer diffraktiven trifokalen IOL (AT LISA tri 839MP, Carl Zeiss Meditec AG, Jena, Deutschland) wurde an einer in Rostock\n\t\t\t\t\tentwickelten optischen Bank f\u00fcr unterschiedliche Pupillendurchmesser aufgenommen. Anschlie\u00dfend wurde ein speziell angepasster Bildverarbeitungsalgorithmus auf die Messungen angewandt, der\n\t\t\t\t\tdie Generierung von Durchfokuskurven erlaubt. Zus\u00e4tzlich wurden Querschnittsbilder der untersuchten IOL unter Verwendung der Lichtblattmethode in einem Fluoresceinbad aufgenommen.<\/jats:p><jats:p>\n          Ergebnisse Die Studie zeigt deutlich die \u00dcberlegenheit der neu entwickelten Methode in Bezug auf die Bildqualit\u00e4t gegen\u00fcber der Lichtblattmethode. Neben den einzelnen Fokuspunkten\n\t\t\t\t\tk\u00f6nnen in den Querschnittsbildern der neuen Methode sowohl feine Fokusstrukturen als auch Halos sichtbar gemacht werden. In den generierten Durchfokuskurven lassen sich 3 Intensit\u00e4tsspitzen\n\t\t\t\t\terkennen, die den Nah-, Intermedi\u00e4r- und Fernfokus der getesteten MIOL darstellen und mittels Lichtblattmethoden nicht darstellbar sind.<\/jats:p><jats:p>\n          Schlussfolgerung Das Zusammenspiel der optischen Bank mit dem entwickelten Bildverarbeitungsalgorithmus erm\u00f6glicht ein detaillierteres Verst\u00e4ndnis der Bildentstehung und\n\t\t\t\t\tFalschlichterscheinungen von IOLs, was mit der bisherigen Lichtblattmethode aufgrund technischer Beschr\u00e4nkungen nur begrenzt m\u00f6glich war. Dar\u00fcber hinaus lassen sich weitere Gr\u00f6\u00dfen wie z.\u200aB.\n\t\t\t\t\tdie Durchfokuskurve quantitativ
