  • Patent number: 9381081
    Abstract: For easy handling at placement of intra ocular lenses (IOLs) for cataract operations, these are equipped with helical haptics of memory materials circumferring the lens. Said haptics adhere to the rim of the lens as long as being cooled down to constriction temperature. On regaining body temperature the haptics expand and fit into the ridges of the eye's capsule sack. Accommodation then is achieved with constriction of the capsule sack by pressure transfer to the rim of the lens to form its shape, in multiplying it with some protrusion towards the pupil.

    Abstract: Systems, devices, and methods are presented for a prosthetic injectable intraocular lens. One or more silicone elastomeric patches located outside the optical path on the anterior side but away from the equator can be accessed by surgical needles in order to fill or adjust optically clear fluid within the lens. The fluid can be adjusted in order to set a base dioptric power of the lens and otherwise adjust a lens after its initial insertion. The elastomeric patches are sized so that they self-seal after a needle is withdrawn. A straight or stepped slit in the patch can allow a blunt needle to more easily access the interior of the lens.

  • Publication number: 20140163675
    Abstract: A method and related apparatus to treat a cataract where the cataractous lens is pierced and the resulting opening is mechanically maintained using a lens system device such as a pinhole device, expandable tubular leas, a stent or similar small diameter device, some of which are capable of supporting a secondary intraocular lens. The resulting passageway or lumen created in the cataractous lens allows visible light to better reach the retina, thus improving vision. This lens system device that can be placed into an in situ cataract provides for a much simpler surgical technique and reduces related pre and post operative procedures and potential complications. Intraocular lenses may also be used in concert with this invention. The apparatus and technique can be applied to humans as well as animals.

    Abstract: A deformable intracapsular implant device for shaping an enucleated lens capsule sac for use in cataract procedures and refractive lensectomy procedures. In one embodiment, the intraocular implant devices rely on thin film shape memory alloys and combine with the post-phaco capsular sac to provide a biomimetic complex that can mimic the energy-absorbing and energy-releasing characteristics of a young accommodative lens capsule. In another embodiment, the capsular shaping body is combined with an adaptive optic. The peripheral capsular shaping body carries at least one fluid-filled interior chamber that communicates with a space in a adaptive optic portion that has a deformable lens surface. The flexing of the peripheral shaping body in response to zonular tensioning and de-tensioning provides an inventive adaptive optics mechanism wherein fluid media flows between the respective chambers “adapts” the optic to increase and decrease the power thereof.
