  • Publication number: 20220128839
    Abstract: An ophthalmic device is formed by additive fabrication, the optical device having an optical surface with a surface roughness on the order of less than 10 microns. A method is provided for making an ophthalmic device including an optical surface having a surface roughness of less than 10 microns by depositing on a stage in a first relative position a first lamina of particulates having a size less than 10 microns and in select configurations less than two microns and certain configurations less than one micron, and, synergistically stimulating the first lamina of particulates to form a first solidified layer.

  • Publication number: 20080185744
    Abstract: A thermal conductive system for curing ophthalmic devices within molds includes pairs of lower and upper heating units that are relatively displaceable for both clamping anterior and posterior mold parts together and conducting heat through the mold parts for curing the ophthalmic devices. The molds can be mounted in thermal engagement with the lower heating units, and the molds can be moved together with the lower heating units into thermal engagement with the upper heating units. Control systems individually regulate the temperatures of the heating units.

  • Patent number: 7311194
    Abstract: The present invention provides a fixture for supporting a two optic accommodating intraocular lens device. The fixture is capable of holding the device while taking measurements or performing manufacturing process steps on the device. In a preferred embodiment, the fixture supports the device along the periphery of the posterior optic thereof such that the haptics and anterior optic extend freely therefrom. As such, testing and/or processing of the optics during their accommodative and unaccomodative positions may be taken.

  • Patent number: 7281699
    Abstract: The present invention provides a holder for supporting a two optic accommodating intraocular lens device. The holder is capable of holding the device while taking measurements or performing manufacturing process steps on the device and/or packaging the device. In a preferred embodiment, the holder supports the device along the haptics thereof such that the optics remain untouched and unobstructed by the holder. As such, testing and/or processing of the optics during their accommodative and unaccomodative positions may be taken, and the device may be safely packaged and shipped with the holder.
