Optimierung der Visualisierungstechnik für Strahlenverläufe durch Intraokularlinsen zur Charakterisierung multifokaler Abbildungseigenschaften von Fresnel-Zonenplatten

Zusammenfassung

Die Anwendung der diffraktiven Eigenschaften von Fresnel-Zonenplatten bietet die Möglichkeit des Designs von Intraokularlinsen mit mehreren Fokussen. Derartige Intraokularlinsen können durch Anwendung der 2-Photonen-Polymerisation (2PP) hergestellt werden. Dieser Beitrag erläutert dieses Konzept und zeigt Prinzipien der Visualisierung von Fokuseigenschaften derartiger Implantate.

Abstract

The utilisation of the diffractive properties of Fresnel zone plates offers the possibility of intraocular lens designs with multiple foci. Such intraocular lenses can be manufactured by two-photon polymerisation (2PP). This paper explains the underlying concept and shows the principles for visualisation of the focus properties of such implants.
