Abstract
An ophthalmological device () includes an optical transmission system () for transmitting femtosecond laser pulses (L) onto a projection lens () for projection onto or into the eye tissue (). The device () also includes a lens interchange device () designed for interchanging and connecting different projection lenses () to the optical transmission system (). The lens interchange device () includes a number of different projection lenses () which are connected mechanically to one another and which can be fed to the optical transmission system () by a rotational or translational movement in order to connect the former to the optical transmission system (). The lens interchange device () makes it possible for a user to flexibly and efficiently change the projection lens () so that the projection lens () can be changed or altered without great expenditure of time and without using a varifocal lens, even between different applications and treatment steps.
