摘要:
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.
