Abstract:
An artificial eye lens having an integral optical part which has, viewed in the direction of an optical principal axis of the eye lens, a first optical side and an opposite, second optical side. The optical part is formed with a structure having birefringence, where the birefringent structure in the integral optical part is formed as a laser structure. A method for producing an artificial eye lens, where the birefringent structure is produced with a laser apparatus, and a pulsed laser beam having a pulse length of between 100 fs and 20 ps, a wavelength of between 320 nm and 1100 nm, a pulse repetition rate of between 1 kHz and 10 MHz, a focus diameter of less than 5 μm, and a power density of greater than 106 W/cm2.
