An opthalmologic cutting device having a base support section for attachmentwith a movement generating device and a tip with a blade section. The blade sectionpreferably has upper and lower edges, and a forward aspiration free edge extendingbetween them, with the upper edge having a shorter longitudinal length comparedwith the lower edge and where the forward edge slopes down from a distal end of theupper edge to a distal end of the lower edge, and the lower edge presenting a materialcontact surface that is thinner in thickness than the upper edge. A slope backin the proximal direction of the forward edge of, for example, 10 to 45 degreeswith a straight and/or curving forward edge or a combination of a straight andforward edge sections is preferred. Embodiments of the blade include a bladeconverging in thickness from top to bottom and one having a curved upper forwardedge region and one with a lower edge that has a distal straight section and a recessedsection positioned proximal of said distal straight section. The forward edgeis also preferably defined by longitudinally diverging, opposing side walls.
