摘要:
A solution for the individual automatic rough positioning of ophthalmological equipment with respect to ensure the diagnostic or therapeutic treatment of the patient. The assembly includes a positioning aid and a control unit for the automatic alignment of the axis of vision of the eye with the optical axis of the ophthalmological equipment. The positioning aid includes a chin rest and a forehead support which have corresponding controllable actuating devices. The assembly has an additional measuring device for recording the geometry of the face of the patient.

A contact glass for ophthalmic surgery, including a concave anterior lens surface for placement on the eye and a suction channel annularly surrounding the periphery of the anterior lens surface. The suction channel allows the contact glass to be fixed to the eye by means of a vacuum, it is envisaged that the suction channel comprise a multiplicity of suction orifices, which are annularly arranged with respect to the anterior lens surface and through which the vacuum acts on the eye.
摘要:
Combined equipment for non-contacting determination of axial length (AL), anterior chamber depth (VKT) and corneal curvature (HHK) of the eye, are also important for the selection of the intraocular lens IOL to be implanted, particularly the selection of an intraocular lens (IOL) to be implanted, preferably with fixation of the eye by means of a fixating lamp and/or illumination through light sources grouped eccentrically about the observation axis.

The invention is directed to an arrangement for tiltably journalling an ophthalmologic treatment and/or examining apparatus. The arrangement includes a mount and an arcuate guide fixedly attached at an end thereof to the mount. Guide elements are mounted on the apparatus for movably guiding the apparatus along the arcuate guide to tilt the apparatus to a desired position. A pressure-spring device has a first end pivotally connected to the apparatus and a second end pivotally connected to the mount whereby the weight of the apparatus is compensated as the apparatus is tilted when moved along the arcuate guide. The arrangement further includes a mechanism for blocking and deblocking the spring action of the pressure-spring device. A lever assembly imparts a tilting movement to the apparatus. The lever assembly has a first pivot connection whereat the Lever assembly is connected to the mount and a second pivot connection whereat the lever assembly is connected to the apparatus.

For use in connection with a machine tool or the like a covering device comprising a plurality of telescopically interengaging cover boxes movable relative to each other and provided with a sealing lip forming part of a profile of elastic material. This profile comprises a head end which includes the sealing lip and is bevelled on its outside and also includes an anchoring web which engages a gap defined by the respective adjacent cover box and a respective adjacent carrier part. The lower surface of the carrier part forms the supporting surface for the respective cover box for conveying the weight of the latter onto the surface of the respective cover box therebelow. The anchoring web inserted into the gap has associated therewith teeth engaging corresponding teeth provided in the carrier part.

In a contact glass for ophthalmic surgery, which comprises a lens body (22) incorporated into a mount (37), said mount (37) having an anterior lens surface (29) designed to be placed on the eye (2), which anterior lens surface (29) is concave according to a curved surface (K), and an annular gap (44) is formed between the lens body (22) and the mount (37), via which gap a vacuum can be applied for fixing the contact glass (12) to the eye (2), it is envisaged that the mount (37) continues the curved surface (K) in an imaginary extension of the latter or at least does not protrude with respect to said curved surface.
