| 摘要 |
The invention relates to a device for LASIK having the following: a first laser radiation source (12) for generating first laser radiation pulses (14) having a power density for bringing about disruption of the corneal tissue; first means (24, 44, K) for guiding and shaping the first laser radiation pulses into the corneal tissue; a second laser radiation source (46) for generating second laser radiation pulses (48) having a power density for bringing about ablation of corneal tissues; second means (40, 42, 44, 24) for guiding and shaping the second laser radiation pulses relative to the cornea; a controller (50) having a first processing program (56a) for controlling the first means and the first laser radiation pulses for generating a cut (72) in the cornea (60; and having a second processing program (56b) for controlling the second means and the second laser radiation pulses for reshaping and modified the imaging properties of the cornea, wherein the first processing program generates regular corneal surface structures causing a rainbow effect in the imaging properties of the cornea; and a third processing program (56c) controlling the second means and the second laser radiation pulses for removing the indicated regular structures (68).
