  • 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: 20110251630
    Abstract: A handheld instrument for marking a cornea, comprising: a handle; a pendulum coupled to the handle; an eye contact element coupled to the pendulum, the eye contact element comprising an eye contact surface; and a corneal marker comprising a marking element, the corneal marker being rotatably coupled to the pendulum. The marking element is disposed within the eye contact element at a position such that the marking element is capable of contacting a cornea when the eye contact surface is in contact with the eye.

  • Publication number: 20060037871
    Abstract: The present invention provides a holder/package for supporting a two optic accommodating intraocular lens device. The holder/package is capable of holding the device, for example while taking measurements or performing manufacturing process steps on the device and/or for packaging and shipping of the device. In a preferred embodiment, the holder/package supports the device along first and second haptics thereof with the optics substantially untouched by the holder/package.

  • Publication number: 20050070859
    Abstract: The fitment is an elongated connector providing a conduit for aspirant to flow from a pump cartridge to an interior of the collection bag. The connector has a first end configured for attachment to the pump cartridge and a second end for positioning within the interior of the collection bag. The second end also includes at least one notch formed in the connector. The notch acts to prevent the collection bag from sealing off the conduit during surgery so that a sufficient amount of air will remain within the bag to allow a surgeon to air vent an aspiration path during surgery.

  • Publication number: 20050070871
    Abstract: A peristaltic pump cartridge 30 for use in ophthalmic surgery includes a housing 62, a length of surgical tubing 50 attached to the housing 62 for engagement with a pump head 14 of a peristaltic pump 10, and an aspirant collection bag 64 attachable to the housing 62. The bag 64 includes a fitment 98 heat-sealed to the bag 62. No adhesive is required to form a liquid-tight seal between the bag 62 and the fitment 98. The fitment 98 is attachable to the housing 62 for providing a conduit for aspirant to be pumped through the tubing 50 and into an interior of the bag 64.
