Abstract

Ophthalmic surgical blades (734) are manufactured from either a crystalline or polycrystalline material, preferably in the form of a wafer. The method comprises preparing the crystalline or polycrystalline wafers by mounting them and machining trenches into the wafers. Methods for machining the trenches, which form the bevel blade surfaces (752), include a diamond blade saw, laser system, ultrasonic machine, a hot forge press and a router. The wafers are then placed in an etchant solution which isotropically etches the wafers in a uniform manner, such that layers of crystalline or polycrystalline material are removed uniformly, producing single, double or multiple bevel blades (734). Nearly any bevel angle can be machined into the wafer which remains after etching. The resulting radii of the blade edges is 5-500 nm, which is the same caliber as a diamond edged blade, but manufactured at a fraction of the cost. The ophthalmic surgical blades can be used for cataract and refractive surgical procedures, as well as microsurgical, biological and non-medical, non-biological purposes.
