title: Iris intraocular foreign bodies: safe and successful removal through limbus.
abstract: Metallic iris intra ocular foreign body (IOFBs) with minimal ocular damage pose an interventional challenge. We report safe removal of metallic intraocular foreign bodies embedded on the iris, in three cases by use of intraocular magnets. Two eyes had a clear lens with best corrected visual acuity (BCVA) of 20/20, while the third eye had a BCVA of 20/200 with siderotic cataract. Ultrasound biomicroscopy confirmed the superficial impaction of IOFB into the iris. Foreign bodies were successfully removed via the limbal route with a 20 g intravitreal magnet atraumatically in all 3 cases with preservation of their pre-operative BCVA. Case series highlights the usefulness and safety of intraocular magnet for removal of metallic iris foreign bodies in selected cases. Prior ultrasound biomicroscopy to know the actual depth of penetration of IOFB into the iris and preoperative confirmation of magnetic property of IOFB are essential.
