Abstract: A method for enhancing digital images during a microsurgery, e.g., an eye surgery, includes collecting digital images of target anatomy using a digital camera as the target anatomy is illuminated by warm white light. The method includes identifying, via a processor in communication with the digital camera, a predetermined stage of the microsurgery. Within the images, the processor digitally isolates a first pixel region, e.g., a pupil pixel region, from a second pixel region, e.g., an iris pixel region, and adjusts a characteristic of constituent pixels thereof. The method, possibly recorded as instructions in a computer-readable medium, may be used to enhance a red reflex at predetermined stages of an eye surgery. A system includes a lighting source for emitting warm white light having a color temperature of less than about 4000°K, the camera, and the processor.

Abstract: An ophthalmic system for generating a topography of an anterior corneal surface of an eye comprises an illuminator, cameras, and a computer. The illuminator illuminates the anterior corneal surface of the eye with a Placido pattern, which reflects the Placido pattern. Each camera generates an image of the reflected Placido pattern to yield multiple images. At least one camera is oriented off an axis of the eye. For each image, the computer calculates a curvature value for each data point of the image, where a data point corresponds to a surface point of the anterior corneal surface. The calculations yield curvature values for each surface point. The computer determines the curvature at each surface point from one or more curvature values for the surface point. The computer generates the topography of the anterior corneal surface from the curvatures at the surface points of the anterior corneal surface.

Abstract: A retina viewing system and method of using the same includes an ophthalmic microscope, a disposable lens attachment, and an electronic control unit (ECU). The microscope has an optical head and a set of internal focusing lenses, the latter providing the microscope with a variable working distance or focal length. The disposable lens attachment includes a resilient body with a proximal end connected to the optical head and a distal end connected to a high-power/high-diopter distal lens. The ECU executes instructions for viewing a retina or other intraocular anatomy of a patient eye. Execution of the instructions causes the ECU to automatically adjust the variable working distance or focal length of the microscope when viewing an image of the retina through the distal lens.

Abstract: Examples relate to a surgical microscope system, and to a system, a method and a computer program for a surgical microscope system. The system comprises one or more processors and one or more storage devices. The system is configured to obtain intraoperative sensor data of at least a portion of an eye from a Doppler-based imaging sensor of the surgical microscope system. The system is configured to process the intraoperative sensor data to determine infor- mation on a blood flow within the eye. The system is configured to generate a visualization of the blood flow. The system is configured to provide a display signal to a display device of the surgical microscope system based on the visualization of the blood flow within the eye.

Abstract: An optic system assists visualization of eye elements during ophthalmic surgery. The system has optic devices aimed at affecting light emitted by an ophthalmic microscope for observing an eye during surgery. This affecting can be by selecting the wave-length spectrum of the emitted light, tilting a light path of the emitted light and/or by changing the light path of the emitted light from the source to the eye under surgery.

Abstract: An eye implant has a body including (a) a receiver, (b) a first mounting clip and (c) a second mounting clip. The receiver is adapted to hold an intraocular device to be implanted in an eye. The receiver, the first mounting clip and the second mounting clip generally extend along a common arc. A method for implanting an eye implant into an eye of an individual or patient includes the steps of making a comeal incision of the eye, inserting the eye implant into the eye through the comeal incision and securing the eye implant so that the eye implant is bounded by an edge of the pupil and an iridocorneal angle of an anterior chamber of the eye.

Abstract: The ophthalmologic microscope has an illumination device (9) for projecting light onto an eye (10) to be observed and a microscope device (8) with a camera (16) to view the eye. The illumination device (9) generates pulsed light. The light is pulsed at least at twice the frame rate of the camera to reduce flicker. The illumination device (9) uses an array of micro-mirrors as spatial light modulator (24), and the mirrors are controlled for a balanced deflection over the frame cycles, which allows to increase the service life of the microscope.
