An apparatus for LASIK is equipped with the following: a first laser radiation source for generating first laser radiation pulses having a power density for bringing about disruption in corneal tissue; first means for guiding and shaping the first laser radiation pulses into the corneal tissue; a second laser radiation source for generating second laser radiation pulses having a power density for bringing about ablation of corneal tissue; second means for guiding and shaping the second laser radiation pulses in relation to the cornea; a controller with a first treatment program for controlling the first means and the first laser radiation pulses for the purpose of producing an incision (72) in the cornea (60); and with a second treatment program for controlling the second means and the second laser radiation pulses for the purpose of reshaping the cornea and changing its imaging properties, wherein the first treatment program generates regular corneal surface structures (68) which cause a rainbow-glare effect in connection with the imaging properties of the cornea; and a third treatment program which controls the second means and the second laser radiation pulses for the purpose of removing the aforementioned regular structures (68). |
