眼內异物是危害工农兵健康的一种眼科常见病,后果很严重,特別是铁、铜等金属异物,如不及早摘出,可能丧失视力,并破坏整个眼球。据河南医学院统计,工农兵病人占眼內异物病人中的92.33％。眼內异物摘出手术的成败关鍵在于术前定位的准确性;特別是非磁性异物,如铜、铝、石、合金等,因不能用电磁铁吸引,所以对定位的要求更高。河南医学院在提高非磁性异物定位的准确性方面,前后进行了10余次革新,设计出方格定位法。经过反复
Intraocular foreign body is a common eye disease endangering the health of workers and peasants, the consequences are serious, especially iron, copper and other metal foreign bodies, if not excerpt, may lose vision and damage the entire eye. According to Henan Medical College statistics, workers and peasants accounted for 92.33% of patients with intraocular foreign body. Intraocular foreign body extraction surgery is the key to the success or failure of preoperative positioning accuracy; especially non-magnetic foreign bodies such as copper, aluminum, stone, alloy, etc., can not be attracted by the electromagnet, so the positioning of the higher. Henan Medical College to improve the accuracy of non-magnetic foreign body positioning, before and after more than 10 innovations, design grid positioning method. After repeated
