Abstract:
1. A method of treating a vision disorder in a patient, comprising the placement of a fluid-focussed, accommodating intraocular lens (IOL) entirely within an eye of the patient, wherein the lens comprises: a substantially cylindrical fluid chamber having a cylinder wall and an axis, the fluid chamber including a first fluid and an axially displaced second fluid, the fluids being non-miscible and having different indices of refraction, a fluid contact layer where the first fluid and the second fluid contact each other so as to form a meniscus that functions as a lens, said fluid contact layer arranged on the inside of the cylinder wall, a first electrode separated from the first fluid and second fluid by the fluid contact layer, a second electrode acting on the second fluid, a range finder placed in communication with the fluid-focussed, accommodating lens, the range finder including at least an autofocusing sensor and a power source, the range finder controlling the focal length of the lens, the fluid contact layer having a wettability by the second fluid which varies under the application of a voltage between the first electrode and the second electrode, such that the shape of the meniscus varies in dependence on the voltage, wherein the wettability of the fluid contact layer by the second fluid is substantially equal on both sides of the intersection of the meniscus with the contact layer when no voltage is applied between the first and second electrodes, the method comprising the steps of: removing the content of the lens capsule of the eye of the patient; placing the fluid-focussed, accommodating intraocular lens inside a capsular bag of the eye of the patient; fixating the fluid-focussed, accommodating intraocular lens within the capsular bag by way of a securing device that holds and centers the fluid-focussed, accommodating intraocular lens in the capsular bag; and manipulating the application of voltage in order to change the radius of curvature in the meniscus and thereby the focal length of the lens.
