  • Accommodative ocular implant
    Patent number: 8795358
    Abstract: The invention relates to a device (1) for the vision correction of an eye (6), comprising: a converter (3, 3A, 3B, 5A, 5B) which can generate an electrical and/or magnetic and/or electromagnetic signal in response to the mechanical energy generated by a movement of the eye; and a soft lens (2) intended to be aligned with the eye. The converter is positioned in relation to the lens such that the electrical and/or magnetic and/or electromagnetic signal generated during the movement of the eye causes the optical properties of the lens to change. The invention is characterised in that the lens (2) includes a polymer material (7) containing a material (4) having a refractive index that can vary under the action of the electrical and/or magnetic and/or electromagnetic signal generated during a movement of the eye.
    Type: Grant
