Abstract: A laser-based device for non-mechanical, three-dimensional trepanation during cornea transplants comprises a computer-assisted control and regulation unit (4) provided with at least one control computer (5, 6, 7) and at least one display unit (8, 9), as well as a laser source (2) for generating a working laser beam (3) as well as a multi-sensor processing head (1) integrated into which are: an axial beam positioning system (11) into which the working laser beam (3) can be coupled, a focal point tracking unit (12) for the z-position displacement of the focal point (13) of the working laser beam (3) an x-y-scanner unit (14, 15) for the x and y-position displacement of the working laser beam (3), an eye position sensor unit (23, 24, 35, 36) for detection of the position of the eye, and a plasma sensor unit (16, 25) for detection of the plasma glow that occurs during the cornea trepanation.

Abstract: A device is part of an injection system for injecting a foldable intraocular lens (IOL) into a human eye. The device contains a folding area with two pivotably interconnected half-shells which can be pivoted from an open starting position to a closed finishing position. A sheet-like band loop is provided which is secured with a securing end on the first half-shell and is guided displaceably on the second half-shell. In the open starting position, a receiving space for the IOL is formed between the band loop and the two half-shells. By pulling on the displaceably guided band loop, the half-shells can be moved in the direction toward their finishing position. The band loop on the one hand permits reliable and gentle folding of the IOL. At the same time, the band loop permits storage of the IOL, in the unfolded state, in the folding area.
