作者于1957年发展虹膜夹人工晶体,自1958年8月开始使用,是一种有四个环的晶体,前环在晶体上,后环在不同水平,人工晶体位于瞳孔前位置,因此与瞳孔无关联。多年来,作者在形状和环的长度以及环的放置进行小的改良。1963年在外伤性白内障囊外摘出术后放入虹膜夹人工晶体,后环被包埋于虹膜和囊膜间的粘连内。这样支持的晶体不可能在眼内移动。前环失去其作用。于1965年在外伤性无晶体而有囊膜存在的眼放入只有后环的人工晶体。瞳孔大小的改变——收缩的瞳孔可保持晶体很好地在中心;但在散大的瞳孔中,同一晶体可随眼的位置而居任何位置,可以前或后移位。为了防止任何移位,每一病人用缩瞳剂治疗,这可减少移位的发病率几乎至零。不过,这仍不能认为是理想的,因为不是每个病人规律地滴用眼
The author in 1957 the development of iris clamp artificial crystal, since August 1958 began to use, is a crystal with four rings, the first ring in the crystal, the ring at different levels, the artificial lens is located in front of the pupil, so with the pupil Not related. Over the years, the authors made minor improvements in the shape and length of the rings and the placement of the rings. In 1963 after traumatic cataract extracapsular extraction into the iris clamp artificial crystal, the ring is embedded in the iris and the capsule between the adhesions. This support of the crystal can not move in the eye. The anterior ring loses its effect. In 1965 traumatic aphakia and the presence of capsular bag into the ring after only the intraocular lens. Pupil size change - contracting pupil can keep the crystal well in the center; but in the dilated pupil, the same crystal can be anywhere in the eye with the position, you can shift before or after. To prevent any displacement, each patient treated with miosis agents, which can reduce the incidence of displacement almost to zero. However, this still can not be considered as ideal, because not every patient drops eye regularly
