角膜异物是眼科常见的急诊之一,因此剔除角膜异物是一项经常性的处置。由于异物的种类、大小、重量及飞来的速度不同,进入角膜的深浅也不同,处理方法也随之而异。在处理嵌夹于角膜内的磁性金属异物时,有条件的地方,可以借助电磁铁帮助吸取。但在条件较差的基层单位,操作中会遇到一些困难,有时需转院治疗。我们自1980年以来改造了角膜异物针,使之带有磁性,在挑取角膜磁性金属异物时,操作方便,效果满意,方法简便易
Corneal foreign body is one of the common emergency department of ophthalmology, so the removal of corneal foreign body is a recurrent treatment. Due to the type of foreign body, size, weight and flying speed is different into the depth of the cornea is also different, the treatment methods vary. In the treatment of embedded in the cornea within the magnetic metal foreign body, the conditions of place, you can help with the help of electromagnetism. However, in poorly-equipped grass-roots units, they encounter some difficulties in their operation and sometimes need to be referred for treatment. We have reconstructed the corneal foreign body needle since 1980 to make it magnetic. When picking corneal magnetic metal foreign body, it is easy to operate, the effect is satisfactory and the method is simple and easy.
