Abstract
An ophthalmological device for treatment 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 to generate a void volume inside the cornea by ablating cornea tissue with partially overlapping focal spots, whereby two or more focal spots partially overlap in direction of each of three dimensions of the void volume, and to move the focal spot inside the cornea to cut in the cornea a venting channel which connects fluidically the void volume to an escape area and enables venting of gas from the void volume through the venting channel to the escape area.
