ABSTRACT:
A probe for suctioning of ocular tissue includes a hollow suction needle having a lateral opening in a needle region to be placed on the ocular tissue to be suctioned, a laser radiation source, a hollow mirror surface defining an ellipsoidal cavity within the needle region and forming a reflective device with a first focal point within the cavity and a second focal point outside of the cavity for location in the tissue to be suctioned, and a light guide disposed within and extending through the suction needle and interconnecting the laser radiation source and the ellipsoidal cavity. The laser radiation is directed by the light guide to the first focal point and reflected by the hollow mirror surface to the second focal point.
