1. A device for ophthalmic surgery, the device comprising:
- a functional element having a first end region and an opposing second end region, the first end region of the functional element sized and shaped to be coupled to a portion of a laser system and the second end region of the functional element including an applanation element configured to engage a portion of a cornea of an eye to be treated; and
an eye-suction device configured to be selectively, fixedly engaged to the second end region of the functional element and configured to be selectively, fixedly engaged to the eye to be treated, the eye-suction device having a body defining a first fluid pathway of a first suction region, a second fluid pathway of a second suction region, and a third fluid passageway of a third suction region, wherein the first, second, and third suction regions are in fluid communication with at least one vacuum source such that;
application of a partial vacuum to the first suction region fixedly secures the eye-suction device to the eye to be treated upon which the eye-suction device has been placed;
application of a partial vacuum to the second suction region fixedly secures the eye-suction device to the second end region of the functional element; and
application of a partial vacuum to the third suction region fixedly secures the cornea of the eye to be treated to the applanation element of the functional element.

Abstract
The invention relates to a suction ring (2) for ophthalmic surgery, with a first suction region (4), which is designed to suck the suction ring onto an eye (18), and with a second suction region (10), which is designed to aspirate a functional element (12). The functional element and/or the suction ring may exhibit measuring means. The functional element may be formed in the manner of a container, so that it can receive a liquid which in operation is located between the cornea of the eye and a lens.

15. A device for ophthalmic surgery, the device comprising:
-
a container element having a first end region, an opposing second end region having a focusing lens, and a wall extending between the first end region and the second end region to define an interior cavity of the container element, wherein a first opening extends through the wall in fluid communication with the interior cavity adjacent the first end region and a second opening extends through the wall in fluid communication with the interior cavity adjacent the second end region such that a fluid is supplied into the interior cavity to fill a space between the focusing lens and a cornea of an eye to be treated without an applanation element being positioned between the focusing lens and the cornea of the eye to be treated; and an eye-suction device configured to be selectively, fixedly engaged to the first end region of the container element and configured to be selectively, fixedly engaged to an eye to be treated, the eye-suction device having a body defining a first fluid pathway of a first suction region and a second fluid pathway of a second suction region, wherein the first and second suction regions are in fluid communication with at least one vacuum source such that; application of a partial vacuum to the first suction region fixedly secures the eye-suction device to the eye to be treated upon which the eye-suction device has been placed; and application of a partial vacuum to the second suction region fixedly secures the eye-suction device to the first end region of the container element. - View Dependent Claims (16, 17, 18, 19, 20)
