The most important rule in treating patients with an intraocular foreign body is that the primary goal of the intervention, while typically including foreign body removal, is comprehensive anatomical reconstruction of the injured eye so that the best possible visual outcome can be achieved. If the ophthalmologist is unable to perform such surgery, the patient should be referred to a facility where the expertise and personnel are available to address all treatable tissue lesions. If the foreign body is in the posterior segment, vitrectomy is usually necessary. With appropriate management, most eyes have a good chance of regaining and maintaining useful vision.
