20140243443 | HYDROPHILICITY ALTERATION SYSTEM AND METHOD - A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age. | 08-28-2014 |
20160145378 | SELF-WRITING WAVEGUIDE WITH NANOPARTICLES - Technologies are generally described for fabricating a self-writing waveguide. Two photo-reactive liquid monomers, each infused with a photo-initiator, may be mixed and dissolved in a carrier solvent to form a mixture. Nanoparticles may be added to the mixture to form a gel. A focused light beam may be provided to cure one of the monomers, initiating polymerization to form a core of the self-writing waveguide. An optional exposure to an optical source, a heat source, or an electron beam source may cure the other monomer, initiating polymerization to form a cladding of the self-writing waveguide. The self-writing waveguide may be formed in a substantially tubular structure or a planar film structure. | 05-26-2016 |
