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.
本文介绍了一种去除眼内异物的方法，该异物无论是磁性还是非磁性的，普通观察方法均无法看见。眼内异物与因创伤导致的血液和碎屑而变得不透明的介质有关。早期去除非磁性颗粒通常是不可能的，而磁性异物的定位会随着患者或眼球的移动而改变，从而导致磁体应用错误并造成额外的眼内损伤。所有这些问题都通过将眼球内部置于一个“电视屏幕”上得以解决，在这个屏幕上可以持续从二维角度看到异物和镊子，从而以最小的创伤取出异物。
