A device for marking a lenticule, the device comprising: a laser device configured to mark the lenticule in a cornea of an eye using pulsed laser radiation having a plurality of ultrashort pulses, the laser device comprising one or more controllable components (12, 16) configured to control a focus of the pulsed laser radiation; and a control computer configured to instruct the one or more controllable components (12, 16) to: create a lenticule marking in the cornea with the pulsed laser radiation; and create the lenticule in the cornea with the pulsed laser radiation, characterized in that the control computer is configured to instruct the one or more controllable components (12, 16) to create the lenticule marking by: determining a lenticule depth (z l) of the lenticule, and calculating a marking depth (z m) of the lenticule marking as 50 to 300 micrometers (μm) deeper than the lenticule depth (z l); and determining a lenticule perimeter shape and size of the lenticule, and establishing a marking perimeter shape and size of the lenticule marking that substantially matches the lenticule perimeter shape and size. a laser device configured to mark the lenticule in a cornea of an eye using pulsed laser radiation having a plurality of ultrashort pulses, the laser device comprising one or more controllable components (12, 16) configured to control a focus of the pulsed laser radiation; and a control computer configured to instruct the one or more controllable components (12, 16) to: create a lenticule marking in the cornea with the pulsed laser radiation; and create the lenticule in the cornea with the pulsed laser radiation, characterized in that the control computer is configured to instruct the one or more controllable components (12, 16) to create the lenticule marking by: determining a lenticule depth (z l) of the lenticule, and calculating a marking depth (z m) of the lenticule marking as 50 to 300 micrometers (μm) deeper than the lenticule depth (z l); and determining a lenticule perimeter shape and size of the lenticule, and establishing a marking perimeter shape and size of the lenticule marking that substantially matches the lenticule perimeter shape and size. create a lenticule marking in the cornea with the pulsed laser radiation; and create the lenticule in the cornea with the pulsed laser radiation, characterized in that the control computer is configured to instruct the one or more controllable components (12, 16) to create the lenticule marking by: determining a lenticule depth (z l) of the lenticule, and calculating a marking depth (z m) of the lenticule marking as 50 to 300 micrometers (μm) deeper than the lenticule depth (z l); and determining a lenticule perimeter shape and size of the lenticule, and establishing a marking perimeter shape and size of the lenticule marking that substantially matches the lenticule perimeter shape and size. determining a lenticule depth (z l) of the lenticule, and calculating a marking depth (z m) of the lenticule marking as 50 to 300 micrometers (μm) deeper than the lenticule depth (z l); and determining a lenticule perimeter shape and size of the lenticule, and establishing a marking perimeter shape and size of the lenticule marking that substantially matches the lenticule perimeter shape and size.
