The invention relates to an image reversion system () which enables an image reversion and beam transposition of a plurality of observation beam paths (and) to be carried out simultaneously. The system includes at least one Porro prism system and is designed in such a way that it can be arranged in a convergent beam path. The inventive system is suitable as an image reversion system in an ancillary module for operational microscopes used in ophthalmoscopy due to the low overall height thereof.

A medical instrument arrangement includes an operation microscope system ( ) and a carrier unit ( ) carrying the operation microscope ( ). The medical instrument arrangement is at least partially covered by a drape ( ). The air inside the drape ( ) is removed by a suction unit. The drape ( ) is fixed to a portion of the carrier unit ( ) at a collar ( ). By operating the suction unit at different suction rates, disturbing vibrations of the system during a surgical procedure can be minimized.

An applicator for treatment of an elevated internal ocular pressure by means of laser radiation has a handpiece, which releasably surrounds a fiber optic light guide on its exit side end. A sleeve portion is releasably connected to the exit side end of the light guide, a condensing optical element being provided in the sleeve portion, optically dimensioned and arranged in the sleeve portion at a distance from the exit side end of the light guide such that the applied laser radiation can be focused in the ciliary body of the eye on contact of the sleeve portion with the surface of the eye.
