Abstract:
A method for modifying the refractive index of an optical polymeric material. The method comprises continuously irradiating predetermined regions of an optical, polymeric material with femtosecond laser pulses to form a gradient index refractive structure within the material. The optical polymeric material can include a photosensitizer to increase the photoefficiency of the two-photo process resulting in the formation of the observed refractive structures. An optical device includes an optical, polymeric lens material having an anterior surface and posterior surface and an optical axis intersecting the surfaces and at least one laser-modified, GRIN layer disposed between the anterior surface and the posterior surface and arranged along a first axis 45° to 90° to the optical axis. The at least one laser-modified GRIN layer comprises a plurality of adjacent refractive segments characterized by a variation in index of refraction across at least one of at least a portion of the adjacent segments and along each segment.

Claim (Index 1):
A method for providing changes in refractive power of an optical device, the method comprising:\n providing the optical device with an optical, polymeric lens material having an anterior surface and posterior surface and an optical axis intersecting the surfaces; and forming at least one laser-modified, gradient index (GRIN) layer disposed between the anterior surface and the posterior surface with continuous streams of light pulses from a visible or near-IR laser by scanning the continuous streams of light pulses along regions of the optical, polymeric material while varying the scan speed, the average laser power, or both, wherein the at least one laser-modified GRIN layer comprises a plurality of adjacent refractive segments having a continuous change in the index of refraction in relation to the index of refraction of non-modified polymeric material, and the GRIN layer is characterized by a continuous variation in index of refraction of at least one of: (i) a portion of the adjacent refractive segments transverse to the direction scanned; and (ii) a portion of the refractive segments along the direction scanned.
