The tank is connected via a tank valve to a tank feed line which has a first valve for shutting off the tank feed line, wherein during the pressure test prior to the tank being filled through the tank feed line a flow of medium, with the first valve closed, is directed into the tank via a bypass line bridging the first valve, wherein the flow of medium is throttled in the bypass line such that a tank feed pressure acting on the tank valve rises in a controlled manner, wherein the tank valve opens particularly when the tank feed pressure exceeds the pressure prevailing in the tank.

Abstract: A method of performing a capsulotomy comprises applying a light-absorbing agent to a lens capsule of an eye 1; illuminating the lens capsule using a first light beam and recording an image of the lens capsule using a camera 43; analyzing the recorded image and determining whether the light absorbing agent has been correctly applied to the lens capsule; if it is determined that the light absorbing agent has been correctly applied to the lens capsule, directing a shaped second light beam 19 onto a predetermined line on the lens capsule in order to modify a structure of a tissue of the lens capsule. The first light beam can be generated by defocusing the second light beam using a lens 37.

Prior to filling the storage tank (8), a cold accumulator (7) provided upstream of the filling coupling (19) on the end section (30a) of the tank supply line (30) is cooled to a predetermined operational temperature such that the medium which, in a first phase of the filling of the storage tank (8), flows through the tank supply line (30) where it is in particular warmed, is cooled by the cold accumulator (7) to a predetermined desired temperature. When the tank supply line (30) has been cooled due to the effect of the medium flowing back, said cold accumulator (7) is cooled again in a second phase of filling the storage tank (8) by a medium flowing back.
