眼球内异物遗留,属磁性者,若 X 线定位准确,施行磁吸术,一般都不感困难。惟非磁性者,目前尚无可靠的方法。Reed 氏等认为铜为非磁性异物,如进入眼内,电磁铁吸出是无能为力,故常常不能取出或在困难中钳出而损伤眼球。我院过去对此类患者亦感棘手。乃自1962年秋起用各种不同方法不断通过动物试验,初步获得一些钳取异物成功的经验,以后开始在临床上应用。至1963年5月在两例合并外伤性白内障的球内非磁性异物均成功地钳出。其中一例在受伤 Legacy foreign body left, is a magnetic person, if the X-ray positioning accuracy, the implementation of magnetic suction, generally do not feel difficult. However, non-magnetic, there is no reliable method. Reed’s think copper is a non-magnetic foreign body, such as into the eye, aspiration of the electromagnet is powerless, it is often not removed or difficult to clamp out and damage the eye. In the past, our hospital was also very troublesome for such patients. Since the fall of 1962, animal experiments have been continuously carried out by various methods and preliminary experience gained in the successful application of foreign body pliers has been obtained. Clinical application has since started. To May 1963 in the two cases of traumatic cataract intracapsular non-magnetic foreign bodies were successfully pliers. One of the cases was injured
