The surface characteristics of 16 intraocular foreign bodies (IOFB) were studied by scanning electron microscopy (SEM) and with an energy dispersive X-ray analyzer (EDXA). The surfaces of all the IOFBs were rough, stringy and nodular in form, and rusted with sharp edges. Many particle-like contaminants were also adhering to the surface. The nature of these particles could be determined with the use of the EDXA. The spectrum showed two peaks, oxygen and iron, indicating that iron foreign bodies are always oxidized.
