Abstract:
An ophthalmic surgical blade comprising:a thin elongated body having a proximal end and a distal end and a central axis of elongation;the proximal end including top and bottom flat parallel surfaces;the distal end having a single beveled edge blade portion including:a sharp tip lying in alignment with the axis of elongation and lying between the top and bottom surfaces;cutting edges extending laterally and proximally from the tip, the cutting edges defining an angle therebetween of 40.degree. to 140.degree.;angled cutting surfaces extending proximally from the cutting edges and extending proximally toward the top surface, each of the cutting surfaces defining an angle with the bottom surface of 15.degree. to 50.degree.;a generally triangular surface extending from an apex at the tip and proximally diverging to a location of merger with the bottom surface, the generally triangular surface defining an angle with the top surface of 1.degree. to 10.degree.; andthe body having unsharpened side edges including two elongated guide surfaces meeting at an unsharpended apex, the guide surfaces defining an angle of 95.degree. to 160.degree..
