Device and method for the performance of ophthalmological operations
First Claim
1. A device for treating glaucoma by creating openings between the anterior aqueous chamber and Schlemm'"'"'s canal of an eye, comprising a probe adapted for insertion in the anterior aqueous chamber such that one end of the probe is guidable to a separating tissue between the anterior aqueous chamber and Schlemm'"'"'s canal, a separation means arranged at the end of the probe for cutting the separating tissue, and a suction channel extending through the probe and ending in a orifice at the end of the probe, wherein the separation means is arranged in the suction channel at the orifice such that the separating tissue sucked into the suction channel is removable by the separation means.

Abstract
The invention relates to a device for performing ophtalmological operations, especially for treating glaucoma. Said device comprises a probe (8) in which a suction channel (12) is arranged. A cutting tool (11) is arranged in the suction channel (12), by which means separating tissue extending to Schlemm'"'"'s canal and being sucked into the suction channel (12) can be removed. The device enables openings to be created between the front chamber and Schlemm'"'"'s canal in a targeted and careful manner.

23. A method for treating glaucoma by creating openings in a separating tissue between the anterior aqueous chamber and Schlemm'"'"'s canal of an eye comprising the steps of
inserting one end of a probe with a suction channel and a separation means in the anterior aqueous chamber, sucking in a piece of the separating tissue in the suction channel, and detaching the sucked in piece of the separating tissue using the separation means to create an opening.

25. A device for treating glaucoma by creating openings between the anterior aqueous chamber and Schlemm'"'"'s canal of an eye, comprising
a probe adapted for insertion in the anterior aqueous chamber and shaped in such a manner that one end of the probe is guidable to a separating tissue between the anterior aqueous chamber and Schlemm'"'"'s canal, a cutter arranged at the end of the probe in the suction channel at the orifice such that the separating tissue sucked into the suction channel can be cut off by the cutter, and a suction channel extending through the probe and ending in a orifice at the end of the probe, wherein the cutter is arranged.
