ABSTRACT:
The inner needle in a guillotine type ocular cutter is ground and placed within the swaged outer needle in an interference fit, so that a radial force is exerted by said inner needle on said outer needle to better shear the ocular tissue. Further, a positive stop is effected on the drive shaft controlling the inner needle so that the distance from the end of the outer needle port to the tissue is minimized. Alternately, the drive shaft has a dwell exerted on it.
