Abstract:
1. A surgical ophthalmic knife blade for forming an incision in ocular tissue comprising: an ocular surgical blade body extending in a first plane and defining a top planar side and a bottom planar side, wherein the top planar side and the bottom planar side each extend in a respective plane substantially parallel to the first plane, the blade body comprising two opposing cutting edge segments, the two cutting edge segments extending from a tip, each of said two cutting edge segments being configured by blending a first and a second portion along the cutting edge segment, the first portion is concave and the second portion is convex, the first and second portions meet at a juncture which forms a smooth connection, wherein one of the first and second portion extends from the bottom planar side of the blade body, and the other of the first and second portion extends from the top planar side of the blade body, whereby the first and second portions form a hollow design, whereby significantly reduced force is required to penetrate the ocular tissue, resulting in less wound trauma.
