Forceps used for implanting posterior chamber lenses of the Shearing or Sinskey/Kratz type have the disadvantage that they do not permit the lens to be safely guided during implantation. This advantage is avoided by a special pair of forceps (made by Klein ophthalmological instruments of Heidelberg, Germany). The branches of the forceps are designed in such a way that the angle between them and the lens is constantly 130 degrees, thus insuring an unobstructed view into the eye while inserting the lens. Moreover, the lens cannot shift laterally around the branch inserted into the hole. Slight opening of the branch causes the lens to slide off the forceps. With these new implantation forceps the lens can thus be inserted into the eye safely and in a predetermined position during the first stage of implantation.
用于植入剪切式或辛斯基/克拉茨型后房型人工晶状体的镊子存在这样的缺点，即在植入过程中无法安全地引导晶状体。德国海德堡的克莱因眼科器械公司制造的一种特殊镊子避免了这一缺点。该镊子的分支设计成使其与晶状体之间的角度始终为130度，从而在插入晶状体时确保能无阻碍地观察眼内情况。此外，晶状体不会围绕插入孔的分支横向移动。分支的轻微张开会使晶状体从镊子上滑落。因此，使用这些新型植入镊子，在植入的第一阶段就能将晶状体安全地插入眼中并置于预定位置。
