摘要：
An eye surgical cutting tool includes a tubular outer part and an axially movable tubular inner part arranged in the outer part. The outer part has a closed distal end, and the inner part has an open distal end. Both parts have an opening in the tube. Both openings are bounded on the distal side by a distal cutting edge in the respective tube. The axial position of the distal cutting edge of the inner part as a function of the circumferential direction initially proceeds towards the proximal end, and then back to the distal end again. The tool is provided with suction means to have, during use of the cutting tool, ocular tissue extended through the opening of the outer part into the interior of the outer part and to convey severed tissue via the interior of the inner part to a proximal end of the inner part.
