Proposed is an apparatus for assistance in the implantation of a corneal prosthesis in a human eye. The apparatus comprises a laser device for providing focused, pulsed laser radiation, and a control program for the laser device. The control program is designed, when executed, to cause an incision figure to be produced in the tissue of the eye by means of the laser radiation, this incision figure allowing the corneal prosthesis to be inserted. The incision figure in this case comprises a bed incision located entirely in the depth of the corneal material, and further comprises an annular incision, which, within the circumferential line of the bed incision, extends from the latter, along its entire annular circumference, as far as the corneal anterior surface. Preferably, the incision figure further comprises an auxiliary incision, which extends, from a location of the eye surface outside the circumferential line of the bed incision, as far as the bed incision. |
