  • Ophthalmic Apparatuses and Methods
    Publication number: 20070004852
    Abstract: Blue light blocking chromophore (BLBC) ophthalmic devices are disclosed. In an embodiment, BLBC is relatively concentrated in the device center gradually decreasing to the device edge to create a BLBC gradient.

  • Infinite refractive index gradient (IRIG) polymers for ocular implant and contact lens applications
    Publication number: 20070004863
    Abstract: Infinite gradient refractive index ophthalmic devices and methods of making same. The method involves diffusing a monomer which polymerizes to a lower or higher corresponding opposite refractive index polymer into a lower or higher index polymer structure and polymerizing same to create the gradient structure. The resulting polymeric structure is used to manufacture ophthalmic devices, e.g., intraocular lenses.

  • Ultra violet, violet, and blue light filtering polymers for ophthalmic applications
    Publication number: 20060252844
    Abstract: Opthalmic devices, particularity intraocular lenses (IOL), with improved contrast sensitivity and methods of making same. In one aspect, blue light blocking chromophores (BLBC) are diffused into, e.g. an IOL lens body to create a BLBC gradient in the lens. Orange dyes are preferred BLBCs.
