Excerpt

Intraocular foreign bodies (IOFB) are relatively common, presenting in 17% to 41% of penetrating ocular trauma cases.1 They can produce damage to various ocular structures and potentiate a risk for endophthalmitis, retinal detachment, and metallosis, warranting prompt IOFB extraction.1,2 Moreover, IOFBs can be in various shapes, sizes, and composition. They can be removed using a variety of instruments and techniques depending on their size, shape, magnetic properties, location, composition, and associated ocular damage. During IOFB removal, the instrument and the technique offering the greatest control, and the least amount of surgical trauma, should be preferred. However, there are some important issues regarding their removal from the posterior segment. One of them is the difficulty in grasping large, round IOFBs, and the ones with irregular surfaces, such as glass material, with the routine IOFB forceps commercially available because of their smaller bite size. Second, if the scleral incision prepared for IOFB removal is not long or wide enough for its size, and it is stuck in this site, it frequently falls back onto the retina uncontrollably, creating a risk for damaging the retina and the macula.
