Abstract
An artificial eye lens () having an optical part () which has a first optical side () and an opposite, second optical side (). The optical part () has a diffractive grating structure that contributes to an optical imaging property of the optical part (). The diffractive grating structure is an amplitude grating () formed in the optical part () as a laser structure. A method for producing an artificial eye lens () where the amplitude grating () 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 10W/cm.
