By the aid of the preserving solution that was mentioned by McCarey and Kaufman, the so-called MK-medium, it is possible to preserve human corneas up to six days. Now we inform about a method for gaining graft that permits the use of the rotor trephine with its already known advantages, such as low cutting pressure, low deformation of the tissue margines and the possibility of watching the cutting process.
借助麦凯里（McCarey）和考夫曼（Kaufman）提到的保存液，即所谓的MK培养基，可以将人角膜保存长达六天。现在我们介绍一种获取移植片的方法，该方法允许使用具有其已知优点的旋转环钻，例如低切割压力、组织边缘低变形以及能够观察切割过程。
