The metallic foreign body shows some rusting, an indication that it has rested on the iris for a while. Remnants of fibrin surround the foreign body. One would have to compare with the iris color of the other eye to know if some siderosis has already caused the brownish coloration of this iris. This is a typical injury after chiseling.
