Abstract
Embodiments disclosed herein are directed to intraocular lens systems having a plurality of materials therein, with at least some of the materials having a diffraction pattern therein and an electrically-modifiable index of refraction collectively configured to selectively alter an effective focal length of the intraocular lens system. Methods of modifying a focal length of an intraocular lens system are also disclosed.
Claims49
An intraocular lens system, comprising:
- a diffractive lens configured to be implanted in an eye of a subject, the diffractive lens including,
- a first material having a first outer surface;
- a second material having a second outer surface remote from and generally facing away from the first outer surface, wherein at least the first material includes an electrically-modifiable index of refraction;
- and
- an electrically-modifiable diffraction pattern defined between the first material and the second material;
- a first electrode on the first outer surface of the first material;
- a second electrode on the second outer surface of the second material;
- and
- a controller including a processor, operably coupled to the first and second electrodes, the controller configured to selectively bias one or more of the first and second electrodes effective to modify at least the electrically-modifiable index of refraction, the electrically-modifiable diffraction pattern, and an effective focal length of the intraocular lens system from a first effective focal length to a second effective focal length over a selected duration of time that is greater than a duration required for an average human eye to accommodate between the first effective focal length and the second effective focal length.

An intraocular lens system, comprising:
- a diffractive lens configured to be implanted in an eye of a subject, the diffractive lens including,
- a first material having a first outer surface;
- a second material having a second outer surface remote from and generally facing away from the first outer surface, wherein each of the first material and the second material includes an electrically-modifiable index of refraction;
- and
- an electrically-modifiable diffraction pattern at an interface of the first material and the second material;
- a first electrode adjacent to the first material;
- a second electrode adjacent to the second material;
- and
- a controller including a processor, operably coupled to the first and second electrodes, the controller configured to selectively bias one or more of the first and second electrodes effective to modify at least the electrically-modifiable index of refraction, the electrically-modifiable diffraction pattern, and an effective focal length of the intraocular lens system from a first effective focal length to a second effective focal length over a selected duration of time.

An intraocular lens system, comprising:
- a diffractive lens configured to be implanted in an eye of a subject, the diffractive lens including,
- a first material having a first outer surface, a first electrically modifiable index of refraction, and a first diffraction surface defining a first diffraction pattern;
- a second material having a second outer surface remote from and generally facing away from the first outer surface, a second electrically-modifiable index of refraction, and a second diffraction surface defining a second diffraction pattern that is substantially complementary to the first diffraction pattern;
- a first electrode in electrical contact with the first outer surface of the first material;
- a second electrode in electrical contact with the second outer surface of the second material;
- and
- a controller including a processor, operably coupled to the first and second electrodes, the controller configured to selectively bias one or more of the first and second electrodes effective to modify at least the first electrically-modifiable index of refraction, the first diffraction pattern, and an effective focal length of the intraocular lens system from a first effective focal length to a second effective focal length over a selected duration of time that is greater than a duration required for an average human eye to accommodate between the first effective focal length and the second effective focal length.
