  • Publication number: 20240065828
    Abstract: Disclosed herein is a one-piece intraocular lens holder that may contain an interocular lens. The one-piece holder comprises a first portion, a second portion, and at least one integral hinge that connects the first portion to the second portion, wherein one portion comprises an integral annular support that accommodates an intraocular lens and the other portion comprises an integral adaptive feature that exerts a force on the intraocular lens when the intraocular lens is positioned on the integral annular support and the two portions are in a closed position.

  • Publication number: 20230404745
    Abstract: Sterile packaging for an intraocular lens (IOL) delivery system includes a sealed container with an IOL delivery system contained therein, with a cap sealing the container. One or more tamper-evident solutions are provided on the packaging to ensure an indication of non-sterility. This configuration solves certain issues with prior packaging, such as clumsy transfers and bulky packaging which creates storage issues and mitigates sterility barrier risk associated with pouch or blister packaging or other non-rigid package types.

  • Publication number: 20230225857
    Abstract: An intraocular lens (IOL) injector cartridge having one or more modifications from conventional designs which reduce stress and strain in the optic of the IOL during passage through the cartridge. One change includes adding axially-oriented ribs in a funnel portion of the cartridge to enable the cartridge wall to flex outward during passage of the IOL, which is compressed to a great degree in the cartridge lumen. Another modification involves providing a longitudinal step along a segment of the inner lumen which biases one free edge of the optic to tuck or dive under the other free edge and encourage spiral folding as the IOL progresses along the gradually narrowing lumen. The third option is modifying the shape of the lumen within the extreme distal end of the cartridge where the lumen is smallest so that it is neither circular nor oval. Each or all of these modifications may be incorporated into a single cartridge.

  • Patent number: 11000271
    Abstract: A method of attaching a surgical suture to a needle and testing the attachment includes dispensing a length of suture from a spool by using a first suture gripper, and using a surgical needle gripper for holding a surgical needle stationary. A leading end of the suture is inserted into and attached to a receiving end of the surgical needle. A second suture gripper is located between the first suture gripper and the spool. After the second suture gripper is closed for gripping the suture, the second suture gripper is advanced downstream toward the surgical needle to reduce the tension on the suture. The tension on the suture is reduced by moving the second suture gripper a pre-determined distance. The first suture gripper is opened for releasing the suture and the first suture gripper is moved toward the suture spool for re-grasping the suture at a location between the second gripper and the suture spool.
