We describe a new methods to produce an instrument to scrap the cornea. It is made from either a fine needle or a cannula. The material is flattened by means of a laminator or a hammer and a flat metal surface. A sandpaper is used to rough the front end and round it. The tip is slightly bent and the device is submitted to ethylene oxide for sterilization. A handle may be used to hold the instrument, which may be reusable, after washing and sterilization using local heat at the tip, or gas.
