Removal of nonmagnetic and magnetic intraocular foreign bodies with constant visualization.

A method of removing intraocular foreign bodies, magnetic or nonmagnetic, that are invisible to ordinary viewing procedures is presented. Intraocular foreign bodies are associated with media which is opaque from the blood and debris of trauma. Early removal of nonmagnetic particles usually is impossible, while localization of magnetic foreign bodies changes with movement of the patient or the eyeball, causing wrong magnet application and additional intraocular damage. All of this is resolved by placing the inside of the eye on a "television screen" where the foreign body and the forceps are seen constantly in a two dimensional aspect, allowing removal of the object with minimal trauma.
