本文介绍了作者自1962年设计并开始应用于临床的磁棒接力法摘出眼内异物,并从物理学的原理方面对这一手术方法进行了阐述。经过20年的临床应用,证实是一种行之有效的方法;采用这种手术方法,摘出成功率为96%,解决了一些难于摘出的眼内异物的手术问题。器械设计:直径为1、1.5及2毫米的软铁棒,长40～50毫米,前端钝圆,后端为平头,棒的表面 This article describes the method of removing the intraocular foreign body by the magnetic rod relay method which the author designed and started to apply to the clinic in 1962, and expounded the surgical method from the principle of physics. After 20 years of clinical application, it has been proved to be an effective method. With this surgical method, the successful rate of 96% is extracted, which solves the surgical problems of intraocular foreign bodies that are difficult to be extracted. Instrument design: diameter of 1, 1.5 and 2 mm soft iron rod, 40 to 50 mm long, front-end rounded, the back-end is flat, the surface of the stick
