An artificial lens for an eye () is described. According to the present invention, an artificial lens for an eye is now provided, in which the focal width can change. This is realized according to the invention by providing the artificial lens with two or more media () that are flexible in shape as lens elements and that the two media that are flexible in shape stand in direct contact with one another. The media that are flexible in shape are preferably disposed in an uptake container forming a lens body ().

Flexible artificial lens accommodated by means of pressure or electrical condictivity

Optical arrangement for varying a magnification or a refractive power in an optical path, wherein this optical arrangement as a whole encompasses at least two different possible magnifications or refractive powers, comprising a first optical element having a refractive power and a second optical element having a refractive power, characterized in that this optical arrangement comprises at least one optical switch, wherein the first optical element having a refractive power and the second optical element have a refractive power are spaced apart from one another.

Optical arrangement for changing a magnification or a refractive power

A changer includes an axis of rotation for at least one optical element for at least one optical path comprising an optical axis. The changer inserts the optical element into the optical path by a rotary motion or removes it from the optical path. The optical path is one of at least two spatially connected optical paths and the axis of rotation of the changer is located between two parallel lines. The parallel lines run in a plane through the interfaces of the optical axes of the optical paths with one plane, which intersects the optical axes under the same angles and is perpendicular to the plane, which is spanned by the optical axes. The parallel lines are perpendicular to the connecting line between the two interfaces of the optical axes of the optical paths with the one plane, which intersects the optical axes under the same angles.

Changer for optical elements

The invention relates to optics comprising adjustable optical elements and, if desired, lenses of fixed focal lens. By use of an appropriate controller for the adjustable optical elements, characteristics of the optics can be advantageously varied. For this purpose, systems are provided which are suitable for use as surgical stereo-microscope, objective, ocular or zoom. A zoomable imaging optics comprises lenses and of variable optical power, which are oppositely controlled by means of a controller to change an imaging ratio, so that the optical power of the one lens is increased and the optical power of the other lens is decreased. Moreover, the imaging optics may comprise still further assemblies of fixed optical power.

A stereo-examination system including an objective arrangement configured to receive an object-side beam bundle emanating from the object plane and to convert the object-side beam bundle into an image-side beam bundle and a selection arrangement configured to select at least one pair of partial beam bundles from the image side beam bundle. The system also includes an image transmission apparatus configured to generate stereoscopic images of an object positionable in the object plane from the at least one pair of partial beam bundles and an illumination arrangement. The illumination arrangement includes a light source, a beam coupler to superpose a beam cross-section of the illumination beam with the image-side beam bundle, and a field of a plurality of state-changing elements. The elements are selectively switchable between a first state directed and a second state in which light of the illumination beam is and is not directed to the object plane.

An apparatus for treating body tissue includes a treatment instrumentfor treating the body tissue and a measuring unitfor measuring the actual value of a parameter of the body tissue at at least one measuring point. An identifieris connected to the measuring unitfor identifying the body tissue to be treated on the basis of the actual value and for outputting a coordinate signal containing the coordinates of the body tissue to be treated. A positioning devicereceives the coordinate signal and moves the treatment instrumentto the body tissue to be treated. An updating deviceis connected to the measuring unitand the identifierand outputs an updating signal for triggering renewed measurement of the actual value and renewed identification of body tissue to be treated.

A microscopy system for eye surgery with an objective lens is suggested, which provides a retroillumination system to generate a so-called red reflex illumination during an eye-surgical treatment, in particular during a cataract operation.

Microscopy system for eye surgery and method of illumination

The present invention relates to a surgical microscopy system, comprising a surgical microscope, a stand comprising a base and a plurality of pivotally connected arms, the surgical microscope being mounted to one of the arms, wherein the pivotally connected arms are arranged to be movable with respect to each other such that the surgical microscope is movable relative to the base, and wherein a conventionally provided lead is replaced by one or more leads fulfilling the function of the single lead together. The present invention also relates to a surgical microscopy system, wherein data or/and energy is transmitted to the surgical microscope by wireless transmission.
