Abstract
An ophthalmological device for refractive correction of a cornea comprises a laser source, a focusing optical module, a scanner system and an electronic circuit. The electronic circuit is configured to control the scanner system to move the focal spot of the pulsed laser beam generated by the laser source to generate a first part of a void volume ablating cornea tissue inside the first part of the void volume, and to generate a separated second part of the void volume by separating the second part of the void volume as piece of cornea tissue to be removed from the void volume through an incision in the cornea, whereby at least a part of the separated second part is separated from the cornea by the ablated first part.
