Abstract:
The present invention relates to the digitalization of images, and more specifically to a system for activating the digital acquisition of an image with a digitalization device coupled to an optical instrument such as, for example, a microscope, a telescope, a retinograph or a colposcope, which is activated with the foot. Furthermore, the digitalization device is coupled to the optical instruments by means of an adapter element which maybe able to adapt to different sizes or shapes of such devices and instruments, the adapter having a simple manufacturing process, and a reduced manufacturing cost.
Abstract:
OCT-enabled injection for vitreoretinal surgery may involve using an OCT image to detect when a surgical injector penetrates a desired tissue layer of the eye for receiving an injection. The injection may be triggered or automatically actuated based on the detection of the surgical injector from the OCT image.
Abstract:
Die Erfindung betrifft ein Operationsmikroskop (10) für das Erzeugen eines Beobachtungsbildes eines Objektbereichs (12) mit einem Beobachtungsstrahlengang (24, 26), der ein Hauptobjektivsystem (16) durchsetzt. Das Operationsmikroskop (10) enthält eine Strahlengang-Schalteinrichtung (72, 76) für das Auskoppeln von Bildinformation, die in einem ersten Schaltzustand in dem Beobachtungsstrahlengang (24, 26) geführtes Licht auf einen ersten Strahlengang (80, 84) mit Licht der Intensität IT1 und auf einen zweiten Strahlengang (82, 86) mit Licht der Intensität IT2 aufteilt, wobei der erste Strahlengang (80, 84) zu einem Okulareinblick (32, 34) und der zweite Strahlengang (82, 86) zu einer Bilderfassungseinrichtung (40, 46) geführt ist, und die in einem zweiten Schaltzustand das in dem Beobachtungsstrahlengang (24, 26) geführte Licht mit der Intensität IU in den zweiten Strahlengang (82, 86) umlenkt. Erfindungsgemäß weist die Strahlengang-Schalteinrichtung (72) für das Auskoppeln von Bildinformation einen in den Beobachtungsstrahlengang (24) hinein und aus dem Beobachtungsstrahlengang (24) heraus bewegbares Strahlteilerelement (94) auf und enthält ein in den Beobachtungsstrahlengang (24) hinein und aus dem Beobachtungsstrahlengang (24) heraus bewegbares Umlenkelement (92), wobei das Strahlteilerelement (94) bei Anordnen in dem Beobachtungsstrahlengang (24) das darin geführte Licht auf den ersten Strahlengang (80) und den zweiten Strahlengang (82) aufteilt und wobei das Umlenkelement (92) bei Anordnen in dem Beobachtungsstrahlengang (24) das darin geführte Licht in den zweiten Strahlengang (82) umlenkt.
Abstract:
Fluorescence microscopy apparatus for the analysis of a fundus of a sample eye, based on the use of an optical equipment configured to generate a Bessel beam inside a sample eye and an objective configured to increase the numerical aperture of an "objective-cornea-lens" assembly by reducing the overall focal length of the fluorescence microscopy apparatus, also allowing a significant increase in spatial resolution compared to conventional microscopy systems.

Abstract:
Examples of adapters (100) for an ophthalmological imaging apparatus (200, 300) are described herein. The adapter (100) is to support a mobile phone (204) having a camera (206) to capture images of a human eye. The adapter (100) may include a bracket (102) to hold the mobile phone (204). The adapter (100) may also include a coupling unit (106) to couple the bracket (102) to an optical unit (202, 302). The optical unit (202, 302) includes a lens to provide a magnified view of one of an anterior segment and a posterior segment of the human eye. A focal point of the camera (206) of the mobile phone (204), when placed in the bracket (102), and a focal point of the lens lie on a central axis (X) of the coupling unit (106).
Abstract:
The invention relates to an Illumination and observation system (1) for a microscope (2), in particular a microscope for performing eye surgery, a microscope and a microscopying method. The Illumination and observation system (1) comprises a first, second, third and fourth observation pupil (4, 5, 8, 9) for the eyes of two observers such as a surgeon and an assistant, a coaxial illumination (6, 10, 11) in the first, third and fourth observation pupil (4, 8, 9) to generate a red reflex (13) in the first, third and fourth observation pupil (4, 8, 9), and a main illumination (7) in the second observation pupil (5). In order to provide a wide illumination of the surroundings, the main illumination has a larger field of illumination than the coaxial illumination (6, 10, 11) in any of the first, third and fourth observation pupil (4, 8, 9), To provide superior observation quality, in particular for the observer using the second observation pupil (5) and further to be able to generate a visible and homogenous red reflex in the second observation pupil (5), it is provided according to the invention that the main illumination overlaps at least 50 % with the second observation pupil (5) to generate a red reflex (13) in the second observation pupil (5). Further improvements relate to align the main illumination (7) within ±5° to an optical axis (12) of the second observation pupil (5) and to overlap the coaxial illumination (6, 10, 11) at least 50 % with the respective first, third and fourth observation pupil (4, 8, 9).
