  • Patent number: 9730786
    Abstract: An intraocular lens with an anterior ridge designed to provide a space in front of the lens optic.
    Type: Grant

    Date of Patent: August 15, 2017
    Inventor: James Stuart Cumming
  • Patent number: 9655717
    Abstract: An intraocular lens having an optic and at least one semi-rigid, haptic connected to the optic, both of which may be acrylic. The intraocular lens can have a fixed longitudinal length, e.g., the same fixed length pre-operatively and post-operatively. The intraocular lens can resist deformation, despite contraction and relaxation of the ciliary muscle and fibrosis within the capsular bag, after implantation into the eye using, for example, by the semi-rigid haptics. The intraocular lens can be sufficiently flexible to be compressed from an original configuration to a compressed configuration for insertion into the eye through a small incision and return to the original configuration after implantation into the eye.

  • Patent number: 9655716
    Abstract: A plate haptic for an accommodating intraocular lens. The plate haptic has a haptic body that is substantially rigid in a longitudinal direction and substantially flexible in a transverse direction. A chassis is integral to the haptic body. The chassis causes the haptic body to be substantially more rigid in a longitudinal direction than in a transverse direction.

  • Patent number: 9629711
    Abstract: An intraocular lens including a flexible optic and at least one rigid plate haptic connected to the optic. The at least one rigid plate haptic can include a rigid structure. The at least one rigid plate haptic can be resistant to bending from pressure exerted on a distal end of the at least one haptic by contraction of the ciliary muscle. The intraocular lens can be a non-accommodating IOL having a longitudinal length that is fixed and configured to resist deformation by the action of the ciliary muscle. Various embodiments also include accommodating intraocular lenses.

  • Publication number: 20160213463
    Abstract: A plate haptic is used with an intraocular lens optic. The plate haptic comprises: a distal portion having a plurality of opposing projections extending substantially laterally therefrom; and a proximal portion comprising a connecting portion connecting the lens optic to the haptic. The intersection of the proximal portion with each lateral portion forms a plurality of appendages, or paddles, to substantially surround the optic.
