ARTIFICIAL EYE LENS WITH LASER-GENERATED BIREFRINGENT STRUCTURE AND METHOD FOR PRODUCING AN ARTIFICIAL EYE LENS

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...

Beschreibung
Zusammenfassung:	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.
