TREATMENT APPARATUS FOR OPERATIVELY CORRECTING DEFECTIVE VISION OF AN EYE METHOD FOR PRODUCING CONTROL DATA THEREFOR AND METHOD FOR OPERATIVELY CORRECTING DEFECTIVE VISION OF AN EYE

摘要

The present invention relates to a treatment device for surgical correction of near or far vision in an eyeball (3), the treatment device (1) being controlled by a control device (12) and applying a laser beam (2) Wherein the control device 12 is adapted to control the laser device L such that the lenticular volume 18 is isolated in the cornea 5 so that the distance between the volume and the cornea 18 increases, The laser beam 2 can be controlled to emit the laser beam 2 into the cornea 5 so as to form the cornea 5. The control device 12 pre-defines the lenticular-shaped volume 18 such that when the laser device L is controlled, the volume has a minimum thickness d _{M in the} range of 5 to 50 μm. In the case of myopia correction, the minimum thickness d _M is on the edge of the volume 18 and the minimum thickness d _{M in} the case of primitive calibration is in the area of the visual axis OA.
