Abstract:
1. A method for modifying the refractive index of an intraocular lens following the surgical insertion of the intraocular lens in a human eye, the method comprising: identifying and measuring aberrations caused by the intraocular lens resulting from the surgical procedure, the intraocular lens including an optical, polymeric material; determining the position and shape of structures to be patterned into the optical, polymeric material of the lens to correct for the aberrations; and 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, wherein the irradiated regions are characterized by a change in refractive index, exhibit little or no scattering loss, and exhibit no significant differences in a Raman spectrum with respect to a Raman spectrum of non-irradiated optical, polymeric material.
