Apparatus and method for preparing and performing a corneal tattoo

摘要

The present invention provides a planning device (P) for determining control data for the treatment device (1) for preparing a surgical tattoo of the cornea (22) of the eye (3) of the patient, and the cornea (22) of the eye (3). A method of preparing and generating control data relating to a surgical tattoo of a). It is an object of the present invention to provide an artificial iris that is indistinguishable from a natural iris from a cosmetic point of view and that can meet the maximum number of functions of the natural iris with little side effects on the cornea 22 from a medical point of view. It is to describe the apparatus and method for preparing and executing. This object is limited by the generally circular inner edge 15 having an inner diameter and the generally circular outer edge 16 having an outer diameter, based on the measured and functional data introduced. Defining an entirely annular surface 32, the annular surface 32 having a distance and an inclination with respect to the surface of the cornea 23, and with respect to the annular surface 32, the perforation zones 4 are partially or A control data set is generated for the control of the laser device L which defines the pattern of the target points 6 of the cornea 22 which overlaps completely, and the tissue of the cornea is applied by applying a pulsed laser beam 2. The outer edge 16 of the cut and annular surface 32 is achieved by the apparatus and method, having a constant distance to the outer edge of the iris 14.
