1. A method of preparing an illumination fiber optics for an ophthalmic device, the method comprising:
providing an optical fiber, configured to receive illumination light at a proximal end from a light source; and
creating a light-scattering element at a distal end of the optical fiber, configured to receive the illumination light from the optical fiber at a proximal end and to emit the illumination light at a distal end in a wide angle;
wherein the creating the light-scattering element comprises:
(a) providing a hard tool with a nanostructured tool surface relief pattern; and
(b) pressing the tool surface relief pattern of the hard tool onto the distal end of the optical fiber to form a fiber surface relief pattern on the distal end of the optical fiber;
wherein the creating the light-scattering element further comprising:
laser-fusing a silica end-cap to the distal end of the optical fiber to seal air pockets of the fiber surface relief pattern.
