the present invention relates to a planning device for determining control data for a treatment device (1) that allows surgical tattooing of the cornea (22) of an eye (3) of a patient, a corresponding treatment device ( 1) and a method for preparing and generating control data for a treatment device for the surgical tattoo of the cornea of a patient's eye, as well as methods for the surgical tattoo of the cornea (22) of an eye (3). the purpose of this invention is to describe the devices and methods for preparing and performing a corneal tattoo to provide an artificial iris, which makes it possible, in a cosmetic sense, to provide an artificial iris that can barely be distinguished from a natural iris and, in a medical sense, an artificial iris that fulfills the many functions of a natural iris as much as possible with little secondary effort on the cornea (22). this objective is achieved using the corresponding devices and methods, which, based on the measurement data and functional data entered, define a substantially annular surface (32) that is located within the cornea (22) and which is bounded by an edge circular inner (15) with an inner diameter and by a circular outer edge (16) with an outer diameter, where the annular surface (32) has a distance and an inclination with respect to the corneal surface (23), and, for this annular surface (32), a set of control data to control the laser device (l) is generated, which defines a pattern of target points (6) in the cornea (22) with perforation zones (4) with partial or complete intersection, in which, after the application of the pulsed laser beam (2), the corneal tissue is cut and the outer edge (16) of the annular surface (32) has a constant distance relative to the outer edge of the iris ( 14).a presente invenção refere-se a um dispositivo de planejamento para determinar dados de controle para um dispositivo de tratamento (1) que permite a tatuagem cirúrgica da córnea (22) de um olho (3) de um paciente, um disp
