Abstract:
1. A device for eye surgery, the device configured to hold a fluid other than air between a focusing lens and a cornea of an eye during treatment of the eye, the device comprising: suction ring configured to be placed on an eye to be treated, the suction ring having a first suction region adjacent a first end of the suction ring, the first suction region configured to secure the suction ring against the eye through application of a vacuum to a first fluid pathway of the first suction region; and a container member coupled to the suction ring by applying a partial vacuum to a second fluid pathway of a second suction region of the suction ring adjacent a second end of the suction ring, opposite the first end of the suction ring, the container member having a longitudinal axis and an interior chamber for receiving the fluid, the container member including a wall extending from a first axial end of the container member adjacent to the suction ring to an opposite second axial end of the container member and extending around the longitudinal axis, the wall closing the container member laterally to define the interior chamber, wherein a first opening for supplying the fluid to the interior extends through the wall adjacent the first axial end of the container member and a second opening for venting the interior extends through the wall adjacent the second axial end of the container member, wherein the first and second openings are offset relative to one another along the longitudinal axis of the container member, and wherein the second axial end of the wall of the container member is configured to be coupled to the focusing lens of a laser system such that only the fluid is positioned between the focusing lens of the laser system and an outer surface of the eye when the interior chamber is filled with the fluid.
