Title: TECHNIQUE FOR CONTROLLING A CORNEAL ABLATION LASER
Abstract:
A technique for controlling a corneal ablation laser (240) is described. As to a device aspect of the technique, a device (220) comprises a parameter interface (222); a first determination unit (226); a second determination unit (224); a computation unit (228); and a control unit (230). The parameter interface (222) receives an adjustment parameter. The first determination unit (226) determines a first point (502) on a corneal surface (104a). The second determination unit (224) determines a second point (504) on the corneal surface (104a) that is different from the first point (502). The computation unit (228) determines a third point (718) on a line between the first point (502) and the second point (504) according to the adjustment parameter. The computation unit (228) further generates a control program (246) that centers an ablation profile on the third point (718). The control unit (230) controls the corneal ablation laser (240) according to the control program (246).
