  • Patent number: 8945213
    Abstract: A sealing device for use inside a capsular bag after the natural lens has been removed has a plug part adapted to seal a rhexis in a capsular bag, thus preventing displacement through the rhexis of a lens-forming liquid material injected through the rhexis and adapted to replace the natural lens and form an intraocular lens implant. The plug part has a slightly larger area than the capsulorhexis and is made of a deformable polymer. The sealing device further has a removable adjuster connected to the plug part, the adjuster protruding anteriorly from an outer surface of the plug part and being capable of positioning the plug part to a desired location.

  • Patent number: 8900299
    Abstract: A method for prevention of migration of epithelial cells in a capsular bag of an eye of a mammal is provided. The method comprises removing the natural lens of the eye from the capsular bag; introducing an object with at least one sharp edge into the capsular bag, in such a way that said sharp edge contacts the inside of the capsular bag to form a barrier preventing migration of epithelial cells across said barrier; and injecting a lens-forming composition into the capsular bag.

  • Patent number: 7981154
    Abstract: The present invention is in the field of ophthalmic surgery and relates to a method for the prevention of capsular opacification, especially after extraction of the natural lens from the lens capsule of the eye. Particular methods disclosed include replacing the natural lens with a capsule filling implant comprising an injectable material and injecting an agent capable of inhibiting the proliferation of lens epithelial cells, migration of lens epithelial cells, and/or production of extra-cellular matrix by lens epithelial cells into a space between the inserted capsule filling implant and the lens capsule using an instrument having a hydrophobic outer surface such that the composition reaches a germinative zone of the capsular bag.

  • Patent number: 7794697
    Abstract: The present invention addresses the treatment of ocular conditions by the enhancement of lens regeneration. Enhancement of lens regeneration is accomplished by the administration of a composition comprising a polysiloxane polymer having functional acryl groups useful in the preparation of intraocular lenses (IOLs).

  • Publication number: 20070106380
    Abstract: A method for implanting an intraocular lens into the eye of a subject includes placing the intraocular lens into the eye of a subject and administering a drug in an amount sufficient to maintain an accommodative state of the eye. The method further includes permitting at least a portion of the intraocular lens to become coupled to at least a portion of the eye while maintaining the eye in the accommodative state. In certain embodiments, the method may include forming an intraocular lens while maintaining an accommodative state of the eye. In such embodiments, the method may exclude permitting at least a portion of the intraocular lens to become coupled to at least a portion of the capsular bag.
