Zusammenfassung:	The lens has a front surface (29) designed for fixing at an eye, and a low-pressure fixing device for fixing the lens at the eye. 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. Bei einem Kontaktglas für die Augenchirurgie, das eine zum Aufsetzen auf das Auge (2) ausgebildete, konkave Linsenvorderfläche (29) und eine den Rand der Linsenvorderfläche (2) ringförmig umgebenden Saugkanal (44) aufweist, über den das Kontaktglas (12) am Auge (2) mittels Unterdruck befestigbar ist, ist vorgesehen, daß der Saugkanal (44) zum Auge (2) hin eine Vielzahl von ringförmig angeordneten Ansaugöffnungen (45) aufweist, durch die hindurch der Unterdruck auf das Auge (2) wirkt.
