ABSTRACT:
A surgical knife blade of the type primarily intended for making incisions in the eye, though suitable for incising virtually any spherical surface, is disclosed. The blade is uniquely characterized by its construction to include cutting edge bevels of different transverse dimension on the anterior surface of the blade with respect to the transverse dimension of corresponding bevels on the posterior surface of the blade, such that the blade of this invention will incise a substantially straight, perpendicular cut into the eye or other spherical surface.
