    • A method for modifying the refractive index of an optical, polymeric material. The method comprises irradiating select regions of the optical, polymeric material with a focused, visible or near-IR laser having a pulse energy from 0.05 nJ to 1000 nJ. The irradiation results in the formation of refractive optical structures, characterized by a change in refractive index, exhibit little or no scattering loss, and exhibit no significant differences in the Raman spectrum with respect to the non-irradiated optical, polymeric material. The method can be used to modify the refractive index of an intraocular lens following the surgical implantation of the intraocular lens in a human eye. The invention is also directed to an optical device comprising refractive optical structures, wherein the refractive structures are characterized by a change in refractive index, exhibit little or no scattering loss, and exhibit no significant differences in the Raman spectrum with respect to the non-irradiated optical, polymeric material.
    • 用于改变光学聚合物材料的折射率的方法。 该方法包括用具有0.05nJ至1000nJ的脉冲能量的聚焦,可见或近红外激光照射光学聚合物材料的选择区域。 照射导致折射光学结构的形成,其特征在于折射率的变化,显示很少或没有散射损失,并且在拉曼光谱方面相对于未照射的光学聚合物材料没有显着差异。 该方法可以用于在人眼中手术植入人工晶状体后修改眼内透镜的折射率。 本发明还涉及一种包括折射光学结构的光学器件,其中折射结构的特征在于折射率的变化,表现出很少的或没有散射损耗,并且在拉曼光谱方面相对于未辐照的表现没有显着的差异 光学,聚合材料。
