Abstract: Improved corneal lenticule extraction tools which integrate defined angles, tip features, and the use of vacuum into the tool to aid in the removal of the lenticule. The tool has a body and a tip each with an internal air channel. The tip has a straight portion and a curved portion at a distal end, with one or more orifices disposed on the curved portion. The body either has a mechanism for generating a vacuum in the internal air channel, such as a resilient diaphragm, or is connected to an external vacuum source. Use of tip features and angles helps the surgeon find tissue edges during tissue removal. The use of vacuum aids to draw the tissue to the tool and to hold the tissue by the tool. The improved tools improve speed of extraction as well as completeness of extraction so that no tissue is left behind.
