The surface is surrounded by a number of intake openings (45), where the surface is circular in shape, and low-pressure acts on the eye through the openings. An intake channel (44) surrounds the edge of the surface, and the openings open out into the channel. The surface is designed at a lens body (22) that is held in a holder (37), and the openings are formed in the holder.
