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： An accommodative intraocular lens for implantation in an eye within a natural capsular bag includes a first lens part with an optical body transparent to light and defining an optical axis, front and rear optical body surfaces, haptics connected permanently to the optical body and designed to come into engagement with the capsular bag, a flexible membrane connected permanently to the haptics or the optical body, the membrane having a center axis which runs congruently or parallel to the optical axis and is transparent to light, and a second lens part with a hollow cylinder which can be positioned with a proximal end on the front membrane surface of the first lens part such that the hollow cylinder and the membrane can be displaced along the optical axis towards the front optical body surface and thus the rear membrane surface undergoes a change in the radius of curvature thereof.

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： The invention relates to a floor stand for an optical detection device, having a foot part comprising multiple bearing points or a planar standing surface that span a base plane, having a first stand arm which is pivotably connected to the foot part by a first joint on the foot part, and which is connected to a second stand arm by a second joint remote from the foot part, wherein the length of the first stand arm is dimensioned such that the distance between the base plane and the second joint is smaller than the sum of the maximum value for the eye level when seated and the maximum value for the length of the lower leg including the foot when the first stand arm is aligned at 45 degrees in relation to the base plane.

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.

摘要： A method for carrying out a system test of a laser processing system is disclosed. The method includes the execution of a functional test of a control element of the laser processing system. The method further includes the determination of a variable parameter and the determination of an influence of the determined variable parameter on an intended execution of a laser processing by means of the laser processing system. The execution of the functional test of the control element and the determination of the variable parameter overlap at least partially in time.
