Abstract
An ophthalmological device () comprises a controllable optical correction element () for the variable modulation of the wavefront of deflected femtosecond laser pulses. A control module () controls the correction element () as a function of the deflection of the femtosecond laser pulses in such a way that the femtosecond laser pulses are focused into an image area, arranged around the optical axis (z) of the light projection module (), on a defined treatment surface. It is possible by means of the adaptive and dynamic modulation of the wavefront of the deflected laser pulses for the laser pulses to be focused onto the treatment surface in an enlarged image area in conjunction with unchanged projection optics of the light projection module () such that the image field is enlarged in conjunction with an unchanging compact design of a light projection module () suitable for manual application.
