  • Methods of manufacturing coated contact lenses
    Patent number: 11067831
    Abstract: Methods are disclosed for manufacturing a coated contact lens that comprises a polymeric lens body comprising an acid group, a first coating polymer comprising a first amine group ionically bound to the acid group, and a second coating bound to the first coating polymer through covalent linkage between a nitrogen atom of a second amine group on the first coating polymer and an amine-reactive group of the second coating polymer. In some examples the lenses exhibit improved surface properties compared to uncoated lenses, such as reduced adhesion, increased wettability, increased lubricity, and/or increased lipid resistance.

  • Flexible, adjustable lens power liquid crystal cells and lenses
    Patent number: 11003016
    Abstract: A flexible optical element adopting liquid crystals (LCs) as the materials for realizing electrically tunable optics is foldable. A method for manufacturing the flexible element includes patterned photo-polymerization. The LC optics can include a pair of LC layers with orthogonally aligned LC directors for polarizer-free properties, flexible polymeric alignment layers, flexible substrates, and a module for controlling the electric field. The lens power of the LC optics can be changed by controlling the distribution of electric field across the optical zone. Lens power control can be provided using combinations of electrode configurations, drive signals and anchoring strengths in the alignment layers.

  • Complex catalog match system
    Patent number: 10649972
    Abstract: Systems and techniques are provided for a data matching system having a plurality of clients and a master catalog. In a learning phase of a client, the data matching system builds a client matching table for the client and matches the input request to a specific entry in a particular set of entries in the master catalog. In a post-learning phase of the client, the data matching system uses the client matching table to match the input request to a specific entry in a particular set of entries in the master catalog. In a specific implementation, the data matching system uses a two-step match to build the client matching table. In a first step, a plurality of a set of entries in the master catalog is selected for the input request. In a second step, a particular set of entries is selected using a confidence score.

    Abstract: A contact lens has a central region and an annular region surrounding the central region, the central region having a first optical power and the annular region having a second optical power. In a method of measuring the add power, the wavefront aberration of the contact lens is measured; a polynomial is fitted to the measured wavefront aberration. Terms of the polynomial correspond to types of aberration comprising defocus and astigmatism and residual aberrations. The add power is calculated as a defocus corresponding to the residual aberrations.
