Abstract: The invention relates to a treatment apparatus having a modular intraocular lens, which comprises a first part having a haptic and a marking, visible in optical coherence tomography, with known dimensions of said marking and a second part having an optics body and which has a convergence state, in which the second part is in contact with the first part, and a spaced-apart state, in which the second part is spaced apart from the first part, having an optical coherence tomography device, which is configured to record, by means of optical coherence tomography, an OCT cross-sectional image which shows the first part arranged in a capsular bag of an eye and which shows dimensions of the marking in the OCT cross-sectional image, and having an evaluation unit which is configured to create a corrected OCT cross-sectional image by transforming coordinates of the OCT cross-sectional image in such a way that dimensions of the marking in the corrected OCT cross-sectional image are closer to the known dimensions of the ma

Abstract: A treatment apparatus for a cataract treatment of an eye includes a modular intraocular lens including a first part, which includes a haptic configured to contact a capsular bag of the eye in a region of the equator of the capsular bag and thereby to span the capsular bag, and a second part, which includes an optic body, and has a convergence state, in which the second part contacts the first part, and a spaced-apart state, in which the second part is arranged spaced apart from the first part, a measurement system configured to determine, based on a first measurement, a position of the first part in the eye and in the spaced-apart state of the modular intraocular lens, and a controller configured to determine, based on the position of the first part, a refractive power of the optic body which is to be inserted into the eye.

Abstract: An apparatus for OCT-based imaging, a microscopy system and a method for operating a microscopy system, include at least one OCT radiation source and at least one connection device for connecting the apparatus to the microscopy system, an optical connection configured to be established between the OCT radiation source and the light-guide element of the apparatus in a connected state, wherein the microscopy system includes means for detecting a connection state change, and a change-conditional adjustment of the mode of operation of the microscopy system being performable upon the detection of a connection state change.

Abstract: A microscope is provided which includes an optical module, an OCT module, and a control device. The optical module is configured to generate optical image representations. The OCT module is configured to generate tomographic recordings. The control device is configured to determine the relative spatial position of a marking element, in each case from an optical image representation of the marking element and from a tomographic recording of the same marking element.
