摘要： The present solution is directed to the orientation of an eye for diagnostic and/or therapeutic purposes, wherein the line of sight need not coincide with the optical axis of the examination apparatus or treatment apparatus. The invention includes a fixating light source for generating a positionable fixating mark, a device for coupling this fixating mark into a beam path of an ophthalmological apparatus whose imaging optics project the fixating mark on the eye to be examined and/or treated, and a control unit by which the image of the fixating mark can be displayed at different distances and angular positions with respect to the optical axis of the ophthalmological apparatus so that the eye to be examined and/or treated is oriented to this fixating mark by foveal focusing and occupies a defined position with respect to the optical axis of the ophthalmological apparatus.

摘要： A polarization beam splitter selectively decouples detection light onto a detector such that it has a polarization direction that differs from the emitted illumination light. This enables the detection of the light scattered back in the eye lens at a high level of accuracy, since stray light from reflections at optical components of the light path is suppressed. In the generating of photo disruptions or other incisions, the ray exposure of the retina may be reduced in that the incisions being furthest away from the laser are induced first such that laminar gas inclusions with an existence duration time of at least 5 seconds result. In this manner the laser radiation propagated in the direction of the retina in further incisions are scattered and partially reflected such that the influence impinging upon the retina is reduced.

摘要： An ophthalmic instrument for the application of laser radiation in a patient's eye, particularly for the examination and/or surgical laser treatment of the cornea and the lens of the eye, includes a femtosecond laser, an objective and optical assemblies. The optical assemblies are arranged in front of the objective, and selectively vary the focus position in the coordinate direction X,Y and Z either within the region of the cornea or within the region of the lens of the eye. The objective or at least one lens group is movable relative to the eye. The variation of the position of the lens group or objective shifts the focus position from the cornea to the lens of the eye and vice versa.

摘要： The invention relates to a device for machining an object by laser radiation, in particular by using the photodisruption method. Said device comprises an observation device for imaging the object and a laser scanning device by which the laser radiation is passed over a predetermined sector of the object for scanning said sector. According to the invention, such a device includes the observation device with a first lens for imaging the object; the laser scanning device with a second lens, through which the laser radiation is guided, in which both lenses with regard to the dimension of the regions to be produced in the images and/or with regard to their focal intercept are different from each other. This invention alternately images the respective region of the object in a first operating mode by the first lens and in a second operating mode by the second lens. It is thus possible to use in both operating modes a lens adapted to the intended imaging purpose.
