Abstract: Annular cornea implant for inserting into a cornea pocket of the human eye via a narrow, tunnel-shaped access, with the end shape of the cornea implant depending on the shortsightedness or astigmatism to be corrected. To enable the cornea implant to be implanted in the cornea pocket in a simple manner and in an optimum position, the implant has a shape memory which is impressed on the basis of the geometry and/or material of the implant, and is designed in such a way that the deformability from a starting shape enables the insertion of the cornea implant into the cornea pocket via the narrow access, and the cornea implant has an adjustment force in the end shape thereof, which enables an essentially independent unfolding of the cornea implant in the cornea pocket.

Abstract: The invention relates to a device for cutting the cornea of an eye in order to correct the refractive power thereof, with a ring body that can be suctioned onto the eye, with an applanator (7) for deforming the cornea, and with a blade (4) which is guided in a guide plane perpendicular to the axis of the ring body, is mounted in front of the applanator (7) and is used to cut a pocket in the corneal tissue. So as to avoid adversely affecting the cutting depth and therefore the cutting accuracy upon penetration of the holder into the corneal pocket, provision is made that the blade (4) is secured on a blade receptacle (50) of a holder or fixture in such a way that the top side (51) of the blade receptacle (50) does not protrude above the top side (44) of the blade (4), at least within the depth of penetration of the blade receptacle (50) into the cornea.

Abstract: The present invention is directed to an automated determination of the sequence of color caps in a color spot or color arrangement test, such as Farnsworth-Munsell 100-Hue Test for determining the color discrimination of human beings. To that end, on or in the color caps, locations (sites) are fixed, at which magnets can be mounted. The distribution of magnets and voids (absence of magnets) are different for each color cap, among the fixed locations in the color caps and thus encode the color caps. A different type of encoding can be attained by creating variously strong magnetic fields by use of various strength magnets in the color cap. Magnetic field detectors are mounted at suitable points in the surface in which the color caps rest in the tray. Using these magnetic field detectors and corresponding electronics, the sequence of the color caps is determined.
