• Selected nonmagnetic, intraocular foreign bodies can be successfully removed from the posterior segment by a modification of the pars plana vitrectomy technique using foreign-body forceps. Opacities of the ocular media are cleared and the foreign body mobilized using the vitrectomy instrument. The foreign body is extracted, under direct visualization, with forceps. Reflex-free illumination is provided by an intraocular, fiberoptic light source. The globe is supported with a double Flieringa ring to prevent collapse after removal of the formed vitreous. Retinal reattachment surgery can be performed during the same operation if indicated.
