Abstract
The present invention provides an intra-ocular lens (IOL) whose focusing performance can be modified after its implantation in the eye without a need for any invasive procedure. An IOL of the invention has an optical chamber having at least a flexible region that is deformable under influence of a fluid. The IOL further include a reservoir for storing an optical fluid in fluid communication with the optical chamber, and a valve that regulates the fluid communication between the reservoir and the optical chamber. The lens can also include a pump that is actuated by an external energy source to transfer the optical fluid between the reservoir and the optical chamber to change the amount of fluid in the optical chamber, thereby modifying the focusing performance of the IOL.
Claims49
An intraocular lens, comprising
- an optical chamber for receiving an optical fluid and having at least a flexible region deformable under influence of a fluid,
- a refractive optical fluid having an index of refraction greater than about 1.337,
- a reservoir for storing an optical fluid and being in fluid communication with said chamber,
- a valve for regulating the fluid communication between said optical chamber and said reservoir.
The IOL of clain 25, wherein said oscillatory magnetic field has an oscillation frequency substantially similar to said resonant vibrational frequency of said flexible diaphragm to induce a large amplitude oscillation of said flexible diaphragm, thereby causing a flow of the optical fluid through the housing of the pump between the inlet opening and the outlet opening.
An intraocular lens, comprising,
- an optical chamber having at least a flexible region deformable under influence of a fluid,
- a reservoir for storing an optical fluid and being in fluid communication with said chamber,
- a valve for regulating the fluid communication between said optical chamber and said reservoir, and
- a vapor-operated pump capable of being actuated by an energy source positioned external to the eye.
A method for adjusting a focusing performance of an intraocular lens externally of the eye, comprising
- providing an intraocular lens comprising
- an optical chamber for receiving an optical fluid having at least a flexible region deformable under influence of a fluid,
- a refractive optical fluid having an index of refraction greater than about 1.337,
- a reservoir for storing an optical fluid and being in fluid communication with said chamber,
- a valve for regulating the fluid communication between said optical chamber and said reservoir, and
- a pump capable of being actuated by an external energy source;
- actuating said pump by the external energy source to transfer a selected volume of the optical fluid between said reservoir and said optical chamber, thereby adjusting the focusing performance of the intraocular lens.
