We investigate the application of femtosecond laser pulses to the eye lens experimentally. For this purpose we have determined the optimum laser parameters for laser cuts within artificial lenses as well as porcine and sheep lenses in vitro. For low pulse energies, we demonstrate low damage laser cuts that allow a resolution of a few micrometers without occurrence of interfering cavitation bubbles. Furthermore, this talk will discuss the effect of different cut patterns with regard to an increase of the lens elasticity. In addition to simple structures, we currently investigate geometries that are the result of finite element simulations. In order to characterize the mechanical and optical properties of these lenses we have implemented an accommodation setup for the extracted eyeballs.
