Abstract:
An ophthalmic surgical blade, comprising:a thin elongated body having a proximal end and a distal end and a central axis of elongation;b) said proximal end including top and bottom flat parallel surfaces;c) said distal end having a single beveled edge blade portion including:i) a sharp tip lying in alignment with said axis of elongation and lying between said top and bottom surfaces;ii) cutting edges extending laterally and proximally from said tip, said cutting edges defining an angle therebetween of 75.degree. to 85.degree.;iii) angled cutting surfaces extending proximally from said cutting edges and extending proximally toward said top surface, each of said cutting surfaces defining an angle with said bottom surface of 22.degree. to 27.degree.;iv) a generally triangular surface extending from an apex at said tip and proximally diverging to a location of merger with said bottom surface, said generally triangular surface defining an angle with said top surface of 3.degree. to 5.degree.;d) said body having unsharpened side edges including two elongated guide surfaces meeting at an unsharpened apex, said guide surfaces defining an angle of 100.degree. to 140.degree..
