Abstract
An intraocular lens is provided which includes a single optical part, a haptic element, which is coupled to the optical part, and an optical main axis, which penetrates a front face and a rear face of the optical part, the haptic element having a first haptic part, which is in the form of a first ring and extends around the optical part, and at least one second haptic part, which is in the form of a second ring and extends around the optical part and is elastically movable relative to the first haptic part, at least one of the two rings being uneven in the peripheral direction about the optical main axis, at least one of the two rings having exactly two ring valleys and exactly two ring hills.
Claims11
An intraocular lens, comprising:
- a single optical part having a front side and a back side;
- a haptic coupled to the single optical part;
- the intraocular lens defining a main optical axis which passes through the front side and the back side of the single optical part;
- the haptic including a first haptic part which is in a form of a first ring and encircles the single optical part, and at least one second haptic part which is in the form of a second ring and encircles the single optical part and which is elastically movable relative to the first haptic part;
- at least one of the first and second rings having an uneven form in a circumferential direction about the main optical axis;
- the first ring having exactly two first ring valleys and exactly two first ring peaks;
- the second ring having exactly two second ring valleys and exactly two second ring peaks;
- one ring valley of the exactly two first ring valleys and one ring valley of the exactly two second ring valleys being arranged at a same first azimuthal position in a circumferential direction about the main optical axis and another ring valley of the exactly two first ring valleys and another ring valley of the exactly two second ring valleys being arranged at a same second azimuthal position in the circumferential direction about the main optical axis such that the first ring and the second ring are in contact with one another at the same first and second azimuthal positions.
