<p><P>PROBLEM TO BE SOLVED: To provide a device for treating eye tissue using femtosecond laser pulses. <P>SOLUTION: The ophthalmological device 1 comprises an optical transmission system 5 for transmitting femtosecond laser pulses L onto a projection lens 3 for projecting the femtosecond laser pulses L onto or into the eye tissue 21. The device 1 also comprises a lens interchange device 4 designed for interchanging and connecting different projection lenses 3 to the optical transmission system 5. The lens interchange device 4 comprises a number of different projection lenses 3 which are connected mechanically to one another and which can be fed to the optical transmission system 5 by a rotational movementϕin order to connect the former to the optical transmission system 5. The lens interchange device 4 makes it possible for a user to flexibly and efficiently change the projection lens 3 so that the projection lens 3 can be changed or altered without great expenditure of time and without using a varifocal lens, even between different applications and treatment steps. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
