Abstract

The present technology is directed to an adjustable power intraocular lens comprising a container, an optical fluid in the container, and a transport substance in solution with the optical fluid. The container has an optical component and a peripheral component extending around at least a portion of the optical component. The optical component has an anterior optical element, a posterior optical element, and a fluid chamber having a chamber volume between the anterior optical element and the posterior optical element. The transport substance is configured to pass through the container. The adjustable power intraocular lens further comprises volume control elements in the container. The volume control elements are configured to be activated by a non-invasive energy and upon activation release the transport substance into the optical fluid to decrease the chamber volume and/or absorb the transport substance from the optical fluid to increase the chamber volume.

First claim

We claim:

1 . An adjustable power intraocular lens, comprising:
a container having an optical component and a peripheral component extending around at least a portion of the optical component, wherein the optical component has an anterior optical element, a posterior optical element, and a fluid chamber having a chamber volume between the anterior optical element and the posterior optical element; an optical fluid in the container; a transport substance in solution with the optical fluid, wherein the transport substance is configured to pass through the container; and a plurality of compartments in the peripheral component, wherein the plurality of compartments include:
a first compartment containing first volume control elements configured to release the transport substance into the optical fluid to decrease the chamber volume; and
a second compartment containing second volume control elements configured to absorb the transport substance from the optical fluid to increase the chamber volume,
wherein, in response to energy delivered non-invasively, the first volume control elements release the transport substance or the second volume control elements absorb the transport substance.

2 . The adjustable power intraocular lens of claim 1 wherein:
the first volume control elements are activated by a first type of energy delivered non-invasively; and
the second volume control elements are active by a second type of energy delivered non-invasively, and wherein the second type of energy is different than the first type of energy.

3 . The adjustable power intraocular lens of claim 2 wherein:
the first type of energy is selected from a group including laser energy, ultrasonic energy, electrical energy and infrared energy; and
the second type of energy is a different type of energy selected from the group.

4 . The adjustable power intraocular lens of claim 1 wherein:
the first volume control elements are configured to be activated by a type of energy delivered non-invasively at a first wavelength or frequency; and
the second volume control elements are configured to be activated by the same type of energy delivered non-invasively at a second wavelength or frequency different than the first wavelength or frequency.

5 . The adjustable power intraocular lens of claim 4 wherein the energy is laser energy, the first wavelength is in a first bandwidth, and the second wavelength is in a second bandwidth outside of the first bandwidth.

6 . The adjustable power intraocular lens of claim 4 wherein the energy is ultrasonic energy, the first frequency is in a first frequency range, and the second frequency is in a second frequency range different that the first frequency range.

7 . The adjustable power intraocular lens of claim 4 wherein the energy is radiofrequency energy, the first frequency is in a first frequency range, and the second frequency is in a second frequency range different that the first frequency range.

8 . The adjustable power intraocular lens of claim 1 wherein the optical fluid comprises an oil and the transport substance comprises water.

9 . The adjustable power intraocular lens of claim 1 wherein:
the peripheral component comprises an outer fluid reservoir; and
the optical component comprises an accommodating optical component in fluid communication with the peripheral component, and wherein the optical fluid flows between the peripheral component and the optical component in response to movement of ciliary muscles of a native eye.

10 . The adjustable power intraocular lens of claim 9 wherein:
the optical fluid comprises an oil;
the transport substance comprises water;
at least a portion of the transport substance released by the first volume control elements is configured to pass out of the container thereby decreasing a volume of matter in the fluid chamber; and
absorption of the transport substance by the second volume control elements causes additional transport fluid from outside the container to pass into the container thereby increasing the volume of matter in the fluid chamber.

11 . The adjustable power intraocular lens of claim 1 , further comprising a connecting barrier between the plurality of compartments and the optical component, and wherein the connecting barrier is configured to deform to adjust the chamber volume in response to the energy delivered non-invasively.

12 . The adjustable power intraocular lens of claim 1 wherein:
the first compartment is configured to contain a first volume of first volume control elements;
the second compartment is configured to contain a second volume of second volume control elements, and
the first volume is isolated from the second volume.

13 . The adjustable power intraocular lens of claim 12 wherein the plurality of compartments further include:
a third compartment configured to contain a third volume of first volume control elements; and
a fourth compartment configured to contain a fourth volume of second volume control elements,
wherein the first, second, third, and fourth compartments are configured to isolate the associated first, second, third, and fourth volumes, respectively, from one another.

14 . The adjustable power intraocular lens of claim 1 wherein the first compartment is positioned on a first side of the optical component, and wherein the second compartment is positioned on a second side of the optical component opposite the first side.

15 . The adjustable power intraocular lens of claim 1 wherein the plurality of compartments are positioned around an optical axis of the optical component.
