    Abstract: Postoperative lens position is predicted on the basis of known measured values, such as the corneal thickness, the depth of the anterior chamber, the eye length, and the distances of the capsular bag equator and/or of the lens haptic from the anterior surface of the lens. In addition, the calculation also takes into account the attitude of the intraocular lens, for which purpose additional parameters of the pseudophakic eye are used that have not previously been taken into consideration. The proposed method is suitable for a more exact prediction of the strength and nature of an intraocular lens to be implanted in a pseudophakic eye in the context of cataract surgery or of a refractive intervention. The method is based on the use of suitable calculation methods, e.g. geometric optical formulae, or of ray tracing.

The optical system includes a distal optical element, at least one relay lens and an eyepiece lens in which the optical system can be integrated within at least one instrument or be provided using a releasable module. Additionally, at least one of a viewing assembly and illumination assembly of at least one medical diagnostic instrument can be assembled using a series of components that are connected by interlocking features.

  • Patent number: 10548459
    Abstract: A medical imaging system comprises a teleoperational assembly and a processing unit configured for receiving a roll position indicator for an imaging instrument coupled to the teleoperational assembly. The imaging instrument has a view angle other than 0° relative to an optical axis of the imaging instrument, and the imaging instrument is a stereoscopic imaging instrument including first and second image sources. The processing unit is further configured for: obtaining first image data from the imaging instrument at a first roll position; obtaining subsequent image data from the imaging instrument at a second roll position; and, responsive to a roll movement of the imaging instrument between the first and second roll positions, transitioning between presentation of the first image data on a user display and presentation of the subsequent image data on the user display. The transition includes changing a position of presentation of the first and second image sources.

  • Patent number: 10545326
    Abstract: An illumination and observation system (1) for an ophthalmic surgical microscope (2) has first, second, third and fourth observation pupils (4, 5, 8, 9) for two observers, a coaxial illumination (6, 10, 11) in the first, third and fourth observation pupils to generate a red reflex (13) therein, and a main illumination (7) in the second observation pupil. For widely illuminating the surroundings, the main illumination has a larger illumination field than the coaxial illumination in any of the first, third and fourth observation pupils. For superior observation quality and a visible and homogenous red reflex in the second observation pupil, the main illumination overlaps at least 50% with the second observation pupil. The main illumination may be aligned within ±5° to an optical axis (12) of the second observation pupil and to overlap the coaxial illumination at least 50% with the first, third and fourth observation pupils.

  • Patent number: 10545325
    Abstract: An illumination and observation system (1), in particular for an ophthalmic microscope, comprises a first observation pupil (4) and a second observation pupil (5) for the eyes of an observer such as an assistant. Further, the system comprises a coaxial illumination (6) in the first observation pupil (4) and a main illumination (7), the coaxial illumination (6) being adapted to generate a red reflex (13) in the observed eye in operation and the main illumination having a larger field of illumination than the coaxial illumination (6, 10, 11). To facilitate usage of the system (1) and/or the microscope (2) and to create a superior stereoscopic view using the red reflex (13), a control subsystem (21, 27) is provided which is adapted to automatically adjust an intensity of the main illumination (7) depending on a change in an intensity of the coaxial illumination (6).

  • Patent number: 10481686
    Abstract: An image display device includes: an image display section that displays an image for a user and allows the user to visually recognize external light; a line-of-sight direction and distance detecting section that detects a line-of-sight direction of the user and a distance to an object located in the line-of-sight direction; and a display control section that controls display operation of the image display section. The image display section includes a focal point and convergence changing section that changes a convergence and a focal point of a display image to be projected. The display control section controls the focal point and convergence changing section based on the line-of-sight direction and the distance to the object detected by the line-of-sight direction and distance detecting section.

  • Patent number: 10478058
    Abstract: An optical coherence tomography (OCT) image composed of a plurality of A-scans of a structure is analyzed by defining, for each A-scan, a set of neighboring A-scans surrounding the A-slices scan. Following an optional de-noising step, the neighboring A-scans are aligned in the imaging direction, then a matrix X is formed from the aligned A-scans, and matrix completion is performed to obtain a reduced speckle noise image.

  • Patent number: 10441464
    Abstract: Systems and methods automatically locate optical surfaces of an eye and automatically generate surface models of the optical surfaces. A method includes OCT scanning of an eye. Returning portions of a sample beam are processed to locate a point on the optical surface and first locations on the optical surface within a first radial distance of the point. A first surface model of the optical surface is generated based on the location of the point and the first locations. Returning portions of the sample beam are processed so as to detect second locations on the optical surface beyond the first radial distance and within a second radial distance from the point. A second surface model of the optical surface is generated based on the location of the point on the optical surface and the first and second locations on the optical surface.

  • Patent number: 10437028
    Abstract: The first and second optical elements are held so as to be rotatable relative to each other about an optical axis. An aberration, which can cancel an aberration caused by a color separation prism, is generated from a synthesis of aberrations generated by the first and second optical elements in a case in which the second optical element is positioned at a first position with respect to the first optical element. The aberration generated by the first optical element is cancelled by the aberration generated by the second optical element in a case in which the second optical element is positioned at a second position with respect to the first optical element. The second optical element is positioned at the first position in a case in which the lens device is to be used in a 3-CCD type first camera device, and the second optical element is positioned at the second position with respect to the first optical element in a case in which the lens device is to be used in a single-CCD type second camera device.

  • Patent number: 10426338
    Abstract: A wearable eye tracking system includes a pair of looping coils in a Helmholtz configuration and an additional looping coil. In one configuration, areas enclosed by the pair of looping coils in the Helmholtz configuration are in parallel with each other, while an area enclosed by the additional looping coil is offset from (i.e., not parallel with) the areas enclosed by the pair of looping coils. In this configuration, the pair of looping coils generates uniform magnetic fields between the two areas of the pair of looping coils in a first direction orthogonal to the areas of the pair of looping coils, and the additional looping coil generates additional non-uniform (or divergent) magnetic fields in a second direction transversal to the first direction.
