摘要：
A method for modifying the refractive index of an optical, polymeric material.The method comprises irradiating select regions of the optical, polymeric materialwith a focused, visible or near-IR laser having a pulse energy from 0.05 nJ to 1000nJ. The irradiation results in the formation of refractive optical structures,which exhibit little or no scattering loss. The method can be used to modify therefractive index of an intraocular lens following the surgical implantationof the intraocular lens in a human eye. The invention is also directed to an opticaldevice comprising refractive optical structures, which exhibit little or noscattering loss and are characterized by a positive change in refractive index.
