Abstract
Accommodating intraocular lenses including an optic having an anterior element and a posterior element defining an optic fluid chamber, wherein the optic is aspheric across all powers throughout accommodation or disaccommodation. Intraocular lenses, optionally accommodating, where an optic portion is centered with a midline of a height of the peripheral portion, the height measured in the anterior to posterior direction.
Claims18
An intraocular lens, comprising:
- an optic portion comprising an anterior element, a posterior element, and an optic fluid chamber defined therebetween;
- and
- a haptic coupled to the optic portion comprising a haptic fluid chamber defined therein, wherein the haptic fluid chamber is in fluid communication with the optic fluid chamber through a plurality of fluid channels that allow fluid to flow from the haptic fluid chamber to the optic fluid chamber and from the optic fluid chamber to the haptic fluid chamber, wherein the haptic comprises a closed free end,
- wherein each of the plurality of fluid channels terminate at an uncovered aperture defined within the optic portion.

An intraocular lens, comprising:
- an optic portion comprising an anterior element, a posterior element, and an optic fluid chamber defined therebetween;
- a haptic coupled to the optic portion comprising a haptic fluid chamber defined therein, wherein the haptic fluid chamber is in fluid communication with the optic fluid chamber through a plurality of fluid channels that allow fluid to flow from the haptic fluid chamber to the optic fluid chamber and from the optic fluid chamber to the haptic fluid chamber, wherein the haptic comprises a closed free end,
- wherein the plurality of fluid channels comprise a first fluid channel terminating at a first uncovered aperture defined within the optic portion and a second fluid channel terminating at a second uncovered aperture defined within the optic portion.
An intraocular lens, comprising:
- an optic portion comprising an anterior element, a posterior element, and an optic fluid chamber defined therebetween;
- a first haptic coupled to the optic portion comprising a first haptic fluid chamber, wherein the first haptic fluid chamber is in fluid communication with the optic fluid chamber through a first pair of fluid channels;
- and
- a second haptic coupled to the optic portion comprising a second haptic fluid chamber, wherein the second haptic fluid chamber is in fluid communication with the optic fluid chamber through a second pair of fluid channels, wherein the second pair of fluid channels are positioned diametrically opposed to the first pair of fluid channels.
