摘要:
Disclosed is a surgical microscopy system having an optical coherence tomography (OCT) facility. The system includes microscopy optics and an OCT system providing an OCT beam path. The OCT system includes an OCT-measuring light source, and a beam scanner disposed between the OCT-measuring light source and the objective lens. A beam of OCT measuring light of the OCT system traverses the objective lens and is directed onto the object region. The OCT system further comprises a zoom system disposed in the OCT beam path between the OCT-measuring light source and the beam scanner.

A method and a system for determining a selection parameter for selecting an intraocular lens to be inserted into an eye. A data processing system, reads data indicative of an axial position of a portion of an anterior surface of an empty capsular bag of the eye. An axial position parameter is determined, which is representative of the axial position of the portion of the anterior surface, depending on the data. At least one selection parameter is determined for selecting the intraocular lens depending on the determined axial position parameter.

Die Erfindung betrifft ein Ophthalmo-Operationsmikroskop mit einem Mikroskop-Hauptobjektiv 101, einem Beobachtungsstrahlengang 105, 205, der zur Visualisierung eines Objektbereichs 108 das Mikroskop-Hauptobjektiv 101 durchsetzt und mit einem OCT-System 140, 150, 700, 800 zur Aufnahme von Bildern des Objektbereichs 108. Das OCT-System 140, 150, 700, 800 umfasst einen OCT-Abtaststrahlengang 142, 152, 702, 802, der über eine Scanspiegelanordnung 146, 156, 705, 706, 805 zum Objektbereich 108 geführt ist. Erfindungsgemäß ist eine Ophthalmoskopierlupe 132 vorgesehen, die in den Beobachtungsstrahlengang und den OCT-Abtaststrahlengang ein- und ausgeschwenkt werden kann
摘要:
The disclosure relates to an optical system for inspecting an eye, having an OCT system which is configured to generate a measurement beam, which is incident on an object region in a converging manner to form a measurement focus. The OCT system has a beam expander which is disposed along the measurement beam between the scanning system and the objective lens and generates an intermediate focus between the scanning system and the objective lens. The OCT system is configured to generate different values of a beam waist diameter of the beam waist by means of controlling the controllable beam expansion of the beam expander. At the different values of the beam waist diameter, an axial beam waist position of the beam waist is substantially identical.

Die vorliegende Erfindung betrifft ein Mikroskopiesystem zur Abbildung eines in einer Objektebene (1) des Mikroskopiesystems anordenbaren Objekts, wobei das Mikroskopiesystem ein Abbildungssystem (26) mit mehreren optischen Elementen zur Bereitstellung wenigstens eines Paars von Abbildungsstrahlengängen (2a, 2b, 2c, 2d), welche in der Objektebene (1) einen Stereowinkel (a1) einschließen, umfaßt. Dabei weist das Abbildungssystem (26) ein erstes Teilsystem (T1) auf, das eine Mehrzahl von optischen Linsen (4-8, 11, 13, 14) umfaßt, welche von beiden Abbildungsstrahlengängen (2a, 2b, 2c, 2d) des wenigstens einen Paars von Abbildungsstrahlengängen (2a-2d) gemeinsam durchsetzt sind. Weiter weist das Abbildungssystem (26) ein zweites Teilsystem (T2) auf, das eine Mehrzahl von optischen Linsen (16'-21', 16"-21", 16"'-21"', 16""-21"") umfaßt, welche jeweils von lediglich einem Abbildungsstrahlengang (2a, 2b, 2c, 2d) des wenigstens einen Paars von Abbildungsstrahlengängen (2a, 2b, 2c, 2d) durchsetzt sind. Dabei sind wenigstens zwei Linsen (4, 5, 6) des ersten Teilsystems (T1) und wenigstens zwei Linsen (16'-19', 16"-19", 16"'-19"', 16""-19"") des zweiten Teilsystems (T2) entlang eines gemeinsamen Abbildungsstrahlengangs (2a-2d) relativ zueinander verlagerbar, um jeweils eine Vergrößerung der Abbildung des in der Objektebene (1) anordenbaren Objektes zu ändern.
