Ophthalmic apparatus with a lighting and/or beam therapy ray whose surface intensity distribution can be regulated and device with such an apparatus for eye treatment

An Arrangement having an eye treatment device comprising,

• an ophthalmological apparatus having
• an observation unit;
• an illuminating unit,
• from which a illumination beam emission is emittable in order to observe the eye,
• said illumination beam emission having a planar geometric cross-sectional dimension and a two-dimensional intensity distribution;
• a spatial light modulator having spatial optical properties, but no mechanical adjustment means,
• a second beam emission differing from the illumination beam emission,
• the spatial optical properties of said spatial light modulator are alterable by irradiation with said second beam emission and again reversible,
• in order to confer said planar geometric cross-sectional dimension to a predetermined geometric cross-sectional dimension or said two-dimensional intensity distribution to a predeterminable two-dimensional intensity distribution in the form of a geometric figure with raster-free image portions,
• wherein said geometric figure is mappable using an optical unit of the illuminating optics onto the eye and/or onto the fundus of the eye, in order to evaluate the convexity of the cornea or the fundus of the eye,
• the geometric figure comprises image elements arranged in the manner of a net,
• which are useable for determining the topography of the front surface of the eye;
• and
• a data processing unit,
• wherein the observation unit has an image-recognition unit
• with which the geometric figure mapped on the retina is recognizable and analyzable,
• the analyzed data is transferable to the data processing unit and this controls the treatment device for treatment of the eye.
