Abstract

The invention relates to a treatment apparatus and a method for providing control data for an ophthalmological laser (12) of a treatment apparatus (10) for generating a laser-induced refractive index change, comprising, as steps, determining (S10) irradiation positions (16) for irradiation by laser pulses for the laser-induced refractive index change, wherein first and second laser pulse lengths (28, 30) are provided for the irradiation of the irradiation positions, wherein the first laser pulse length (28) has a shorter laser pulse length than the second laser pulse length (30); setting (S12) preset irradiation positions (24) to the second laser pulse length (30); and providing (S14) the control data for controlling the ophthalmological laser (12), which includes the adjusted second laser pulse length (30) for the preset irradiation positions (24).
