Introduction: This poster shows a surgical technique to remove ferrous intraocular foreign bodies (IOFB).

Materials and Methods: 10 IOFB injuries were treated in the year 2007 in the Department of Ophthalmology, Civico Hospital, Palermo.

Surgical technique: After performing pars plana vitrectomy to free the IOFB from vitreous fibrils and vitreous hemorrhage, we use an intraocular forceps to grasp the IOFB and to extract it trough the sclerotomy. An external electro-magnet (EEM) is placed on the sclerotomy to stop the IOFB during its manipulation and the eventual extension of the sclerotomy.

Results: In all treated cases the IOFB has been always removed avoiding its fall into the vitreous chamber. During the removal of the IOFB, because of the irregularity of its shapes or of the sclerotomy too thin, the IOFB can fall on the retinal surface with serious consequences if posterior pole is touched. The strenght of the EEM keeps the IOFB on the sclerotomy.

Conclusions: The described surgical technique allows an absolute control of the IOFB during the phase of its removal trough the sclerotomy.
