  • Publication number: 20240103201
    Abstract: Methods and apparatus for additive manufacture of an article corresponding with an energy transmissibility image. The article may include a contact lens or intraocular lens. The improvements are directed to repeated application of a monomer according to a pattern corresponding with the energy transmissibility image, such as grayscale image. The method may include intermittent pinning of deposited polymerizable mixture, partial cure, and final cure of the deposited polymerizable mixture. A pattern of multiple defined areas may be manufactured, with each area representing an amount of energy transmissibility associated with that area.
    Type: Application

  • Patent number: 11874435
    Abstract: Improved methods and apparatus for additive manufacture of an ophthalmic lens, such as a contact lens or intraocular lens. The improvements are directed to repeated application of a monomer according to a pattern of energy transmissibility, such as grayscale image. The method includes intermittent pinning of deposited polymerizable mixture and final cure of the deposited polymerizable mixture. A pattern of multiple defied areas may be manufactured, with each area representing an amount of energy transmissibility associated with that area. Each area may have a light value based upon a scale, such as an 8 bit, 16 bit, 32 bit, 64 bit scale or other scale. In some embodiments, each area may refer to a smallest single component of a digital image.

  • Patent number: 11789181
    Abstract: Improved methods and apparatus for additive manufacture of an article with surface qualities conducive to use as an optical element, such as a contact lens. The improvements are directed to repeated application of a monomer according to a pattern of energy transmissibility, such as gray scale image. The method includes intermittent pinning of deposited polymerizable mixture and final cure of the deposited polymerizable mixture. A pattern of multiple defined areas may be manufactured, with each area representing an amount of energy transmissibility associated with that area. Each area may have a light value based upon a scale, such as an 8 bit, 16 bit, 32 bit, 64 bit scale or other scale. In some embodiments, each area may refer to a smallest single component of a digital image.
