Accommodative intraocular lens
An accommodative intraocular lens capable of effectively exerting a focus adjustment function includes an optical portion and a plurality of support portions arranged around the optical portion. The support portion includes an anterior support portion and a posterior support portion, and the anterior support portion presses an anterior capsule and the posterior support portion presses a posterior capsule by the elastic force of the support portion. When the lens capsule is in a distance vision state or in a near vision state, as the pressing force of the anterior capsule against the anterior support portion increases or decreases, the anterior support portion deflects backward or returns forward while maintaining the radial position of the base end portion, so that the tip end portion of the anterior support portion moves backward or forward greatly while maintaining the radial position, and the optical portion moves backward or forward accordingly.
INTRAOCULAR LENS WITH A SPREADABLE HAPTIC
Provided is an intraocular lens having an optical body and having at least one haptic element coupled to the optical body, wherein the at least one haptic element has a first haptic component and at least a second haptic component formed adjacent thereto, which is movable elastically relative to the first haptic component, and having a principal optical axis that penetrates through a front side and a reverse side of the optical body, wherein the haptic element, measured in the direction of the principal optical axis, has a maximum of a first height, wherein the second haptic component is displaceable relative to the first haptic component from a non-spread position to a spread position in such a way that the haptic element, measured in the direction of the principal optical axis, attains a maximum of a second height which is greater than the first height, and, in the spread position, the second haptic component can be locked in place relative to the first haptic component, wherein the first haptic component has at least a first spreading element, and the second haptic component has at least a second spreading element, wherein the first spreading element and the second spreading element, viewed in circumferential direction around the principal optical axis, at least in the spread position, are in a mutually overlapping arrangement and directly adjacent to one another at least in some regions.
Foldable intraocular lens and method of making
A foldable intraocular lens for providing vision contains an optic body that includes an optical zone and a peripheral zone entirely surrounding the optical zone. The optic body has an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis. The anterior face comprises a central face, a peripheral face, and a recessed annular face therebetween that is disposed posterior to the peripheral face. The intraocular lens further comprises at least one haptic that is integrally formed with the peripheral zone. The haptic comprises a distal posterior face, a proximal posterior face, and a step edge disposed at a boundary therebetween. The haptic further comprises a side edge disposed between the optic edge and the step edge. The proximal posterior face and the posterior face of the optic body form a continuous surface. An edge corner is formed by the intersection of the continuous surface with the optic edge, the side edge, and the step edge.

Rotational Stable Intraocular Lens Anchored in Asymmetrical Capsulorhexis
The invention discloses an intraocular lens construction with the lens construction including one or more rotational haptics extending away from the optical component which haptic provide coupling of the lens construction to the rim of at least one asymmetrical capsulorhexis in the capsular bag. The lens construction, fitted with at least one anterior rotational haptic can be positioned inside the capsular bag, or the lens construction fitted with at least one posterior rotational haptic can be positioned at the sulcus plane in front of the capsular bag. Such a lens construction provides rotational stability any type of intraocular lens including any toric intraocular lens.
Intraocular lens
An accommodating intraocular lens (IOL) is provided. The IOL includes an optic having an anterior face and a posterior face. One or more centration lips are disposed directly on the posterior and/or anterior face of the optic or directly on the posterior and/or anterior face of a carrier that holds the optic. Anterior centration lips are configured to center the optic in a lens capsulotomy opening. Posterior centration lips are configured to fixate the optic in a lens capsule and also center the optic in a lens capsulotomy opening.
