1. A method for the treatment of an eye lens, wherein a cut surface is produced inside the crystalline eye lens using multiple laser pulses, and wherein two or more cut surfaces are produced simultaneously in a predetermined arrangement relative to one another, wherein a cut area with a surface area of 1 mm2 to 10 mm2 is produced. 2. The method according to claim 1, wherein bubbles are produced in the eye lens by the laser pulse, the bubbles having a diameter of at most 50 μm. 3. The method according to claim 1, wherein the thickness of the cut surface is limited to at most 5 μm. 4. The method according to claim 1, wherein the cut area is produced by at least 10,000 laser pulses. 5. The method according to claim 1, wherein two successive laser pulses are produced at a distance from one another in such a way that the faults produced by the laser pulses in the eye lens do not touch or overlap one another. 6. The method according to claim 1, wherein multiple cut surfaces are produced in a predetermined arrangement relative to one another. 7. The method according to claim 1, wherein the two or more cut surfaces are produced having forms or partial surfaces of the following bodies: spherical, spherical segment, spherical sector, spherical layer, prismatoid or prism with elliptical, elliptic annular, circular, annular, parallelepipedidal, parallelogram-shaped, rectangular, square, triangular or irregular base area and lateral area, where the base area and lateral area can be flat or curved in order to increase the ability of accommodation of an eye lens by at least two diopters. 8. The method according to claim 1, wherein a cut surface is produced inside the eye lens and the elasticity of the crystalline eye lens is enhanced by the cut surface having forms or partial surfaces of the following bodies: spherical, spherical segment, spherical sector, spherical layer, prismatoid or prism with elliptical, elliptic annular, circular, annular, parallelepipedidal, parallelogram-shaped, rectangular, square, triangular or irregular base area and lateral area, where the base area and lateral area can be flat or curved. 9. The method according to claim 1, wherein the pulse energy of each of the laser pulses is limited to a range from 1 pJ to 1 μJ.
