Abstract

A new corneal trephine, using suction and disposable razor blades, comprised two cones, one revolving inside the other. A slide mechanism was attached to the inner cone that inclined a disposable razor blade either vertically or at 20 degrees, assuring clear view of either side of the incision and more accurate centering. The effective diameter of the cut was varied continuously from 8.5 to 2.0 mm.

摘要

一种新型角膜环钻，采用抽吸装置和一次性剃须刀片，由两个圆锥体组成，一个在另一个内部旋转。一个滑动机构连接到内圆锥体上，可将一次性剃须刀片垂直或倾斜20度，确保清晰观察切口的两侧，并实现更精确的定心。切口的有效直径在8.5至2.0毫米之间连续变化。
