Abstract
A method for producing a surgical knife of a very small size for use in ophthalmic surgery under a microscopic environment having a sharp edge without causing reflection of lights. The surgical knife comprises a handle, and a blade attached to the handle. The blade has a sharp polished cutting edge, a rough machined surface provided inside of the cutting edge having a relatively rough surface area, and an inner flat area. An anti-reflection treatment is provided on an upper and lower surfaces of the blade except for the cutting edge, thereby prohibiting reflection or emission of lights from the knife.
