Abstract

Die vorliegende Erfindung betrifft ein Modul für ophthalmologische Geräte, durch welches die ophthalmologischen Geräte dann in der Lage sind, neben keratometrischen auch topographische Messungen am Auge realisieren zu können. Das vorgeschlagene Topographiemodul verfügt ist vorgesehen für ophthalmologische Geräte mit eine entfernungsunabhängige Keratometrie-Messeinrichtung. Erfindungsgemäß ist das der Erzeugung leuchtender Muster dienende Topographiemodul fest oder beweglich im Strahlengang zwischen dem ophthalmologischen Gerät und dem Auge angeordnet. Die vorhandene Steuereinheit ist in der Lage das Topographiemodul für die Erzeugung von Leuchtmustern entsprechend zu steuern. Ferner ist die vorhandene Auswerteeinheit geeignet, die von der Detektionseinheit aufgenommenen und übertragenen Reflexbilder eines Auges sowohl keratometrisch als auch topographisch auszuwerten. Mit der vorliegenden Lösung wird es möglich, dass ophthalmologische Geräte, die über eine entfernungsunabhängiger Keratometrie-Messeinrichtung verfügen, zusätzlich topographische Messungen am Auge realisieren können.
