An artificial eye lens (1) having an optical part (2) which has a first optical side (4) and an opposite, second optical side (5). The optical part (2) has a diffractive grating structure that contributes to an optical imaging property of the optical part (2). The diffractive grating structure is an amplitude grating (6) formed in the optical part (2) as a laser structure. A method for producing an artificial eye lens (1) where the amplitude grating (6) is produced with a laser apparatus (17), and a pulsed laser beam (22) 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.
An artificial eye lens having an optical part which has, viewed in the direction of an optical principal axis of the artificial eye lens, a first optical side and an opposite, second optical side, wherein the optical part has a diffractive grating structure that contributes to an optical imaging property of the optical part, wherein the diffractive grating structure is an amplitude grating formed at least partially as a bubble formation in the optical part between the first optical side and the second optical side as a laser-generated structure.
A method for producing an artificial eye lens, the method comprising:
An artificial eye lens produced by causing an amplitude grating to be produced in an optical part of the artificial eye lens, wherein the optical part has, viewed in the direction of an optical principal axis of the artificial eye lens, a first optical side and an opposite, second optical side, with a laser apparatus by causing the laser apparatus to generate a pulsed laser beam that acts on the optical part to form the amplitude grating, wherein the amplitude grating is formed, by the laser apparatus, at least partially as a bubble formation in the optical part between the first optical side and the second optical side.
