DEVICE AND PROCESS FOR IMPLEMENTING A TRANSPLANTATION OF THE CORNEA

摘要

A device for implementing a transplantation of the cornea in respect of the human eye includes instruments for detaching from the eye a corneal segment (44) to be replaced, the instruments including a program-controlled laser apparatus which has been set up to make available focused pulsed laser radiation, the laser apparatus including a control program which provides for such a generation of an incision in the cornea by means of the laser radiation that the corneal segment to be replaced is only partly separated from the remaining corneal tissue of the eye. According to an embodiment, the control program for a penetrating keratoplasty provides for the generation of a ring incision (42) in the cornea (36), which along its entire periphery severs the corneal tissue as far as the posterior surface (40) of the cornea and along at least a part of its periphery terminates at a distance from the anterior surface (38) of the cornea.
