摘要： A system and a method for testing a condition of a subject's nervous system using virtual reality technology are described. The method includes displaying a visual stimulus to the subject in a virtual reality environment. Eye and body movements of the subject are tracked as the subject focuses on the visual stimulus. The body movements may include head movements. Based on the eye and body movements, the condition of the subject's nervous system is evaluated and then results of the evaluation describing the subject's nervous system condition is reported to a user, such as a clinician, for further analysis thereof.

摘要： A method for video stabilisation having the following steps: a) providing the a surgical microscope, comprising an image sensor, and a movement detection device which detects a movement of the image sensor and generates corresponding sensor movement data; b) detecting an object field and generating video data of the object field by means of the image sensor and generating image movement data by evaluating the video data; and c) correcting the video data, comprising c1) calculating displacement vector data which only or predominantly indicate a movement of the image sensor but do not or only subordinately indicate a movement within the object field, using the combined use of the sensor movement data, wherein the image movement data which indicate changes in movement of the object field are weighted and/or filtered on the basis of the sensor movement data, and c2) correcting the video data by means of the displacement vector data.

摘要： A container has an ophthalmic injector holding an intraocular lens and a first vessel at least partially filled with a fluid. The intraocular lens is surrounded by the fluid and the first vessel is provided with a lid which closes the first vessel in a fluid-tight manner and which is releasably connected to the first vessel. A second vessel is coupled to the first vessel. A fluid-tight closure is provided between the first vessel and the second vessel, wherein the lid is coupled to the closure by a coupler, and, when the lid is released from the first vessel, the closure is configured, via the coupler, to pass from a closed position to an open position, such that the fluid can flow from the first vessel into the second vessel.

摘要： A device for producing control data for a laser device for the surgical correction of defective vision. The device produces the control data such that the laser emits the laser radiation such that a volume in the cornea is isolated. The device calculates a radius of curvature RCV* to determine the control data, the cornea reduced by the volume having the radius of curvature RCV* and the radius of curvature being site-specific and satisfying the following equation: RCV*(r,φ)=1/((1/RCV(r,φ))+BCOR(r,φ)/(nc−1))+F, wherein RCV(r,φ) is the local radius of curvature of the cornea before the volume is removed, nc is the refractive index of the material of the cornea, F is a coefficient, and BCOR(r,φ) is the local change in refractive force required for the desired correction of defective vision in a plane lying in the vertex of the cornea, and at least two radii r1 and r2 satisfy the equation BCOR(r=r1,φ)≠BCOR(r=r2,φ).

摘要： A low cost fundus camera uses LED light sources placed adjacent the camera's imaging stop, and thereby eliminates the need for optics for introducing the light source to the camera's optical path. Lens reflex in the pupil relay is avoided by using only reflective optics in the pupil relay. Reflex from the LED is mitigated by actuating each LED separately, one at a time, and capturing a separate image with each actuated LED. Reflex-free regions of each captured image are extracted and combined to create a composite reflex-free image.

摘要： The claimed embodiments relate to methods for characterizing a laser beam (24) of a laser processing system (30). The method includes a) providing an aperture arrangement (10) with a plurality of apertures (14) in a work plane (300) of the laser processing system (30) such that the apertures (14) extend within the work plane (300). The method also includes b) scanning the laser beam (24) along a scanning direction (200) parallel to the work plane (300) across the aperture arrangement (10) in such a way that the laser beam (24) at least partially sweeps over the apertures (14). The method also includes c) determining a respective energy of the laser beam (24) transmitted through the apertures (14) during the scanning process, and d) determining an extent of the laser beam (24) along the scanning direction (200) using the determined energy of the laser beam (24) transmitted through a first aperture (14a) of the plurality of apertures (14) and determining an energy parameter of the laser beam (24) on the basis of the determined energy of the laser beam (24) transmitted through a second aperture (14b) of the plurality of apertures (14). In this case, the first aperture (14a) has a predetermined extent along the scanning direction (200), which is smaller than the mean diameter of the laser beam (24) in the work plane (300). In addition, a second aperture (14b) has an extent that is larger than the laser beam (24) in the work plane (300) and is designed to transmit the laser beam (24) essentially completely.
