An ophthalmological device () comprises an optical transmission system () for transmitting femtosecond laser pulses to a projection objective () for projecting the femto-second laser pulses onto or into eye () tissue. The ophthalmological device () further comprises an objective changing device () for changing and connecting the projection objective () to the optical transmission system (). The objective changing device () comprises more than one different projection objectives () connected mechanically with each other, and the objective changing device () is configured to convey one of the projection objectives () to the optical transmission system () for connecting the respective projection objective () to the optical transmission system (). The objective changing device () makes it possible to adapt the laser-based ophthalmological device () for new applications without the need for extensive reconfigurations and/or costly vario-lense objectives.
