An intraocular lens has an optic body, a haptic element mounted on the optic body and having a haptic curvature and a plurality of recesses on the side of the haptic element facing the optic body, a first actuator configured to reversibly change the haptic curvature of the haptic element such that the haptic element is moved away from the optic body from a rest position, a brace arm mounted on the optic body and the longitudinal brace arm end which is configured to be provided a recess when the haptic element is in the rest position, and a second actuator configured to reversibly change, with a change in a property of the second actuator, a brace arm curvature of the brace arm such that the recess in which the longitudinal brace arm end is to be provided can be adjusted with the property of the second actuator.

A plunger for an injector to inject an intraocular lens into the capsular bag of an eye has a deformable cushion and a contact surface with a cutout in which an imaginary reference point is arranged. The plunger has two points groups, each having a design point arranged on an outer contour, an inner contour point arranged on an inner contour, and a reference point. For each of the point groups, the distance from the design point to a circle or a closed curve is equal to the distance from the inner contour point to the reference point, the design point, the inner contour point and the reference point lie on a straight line, and the inner contour point lines between the design point and the reference point. The distance from the inner contour point to the reference point is different for at least two of the point groups.

Systems and methods involving an intraocular implant with input and/or output electronics are described. In some embodiments, the system includes an intraocular lens having at least one optic operably coupled to a haptic, one or more input electronics on the haptic and/or the optic; and one or more output electronics on the haptic and/or the optic for receiving and/or transmitting data.

An intraocular lens (IOL) injector cartridge having one or more modifications from conventional designs which reduce stress and strain in the optic of the IOL during passage through the cartridge. One change includes adding axially-oriented ribs in a funnel portion of the cartridge to enable the cartridge wall to flex outward during passage of the IOL, which is compressed to a great degree in the cartridge lumen. Another modification involves providing a longitudinal step along a segment of the inner lumen which biases one free edge of the optic to tuck or dive under the other free edge and encourage spiral folding as the IOL progresses along the gradually narrowing lumen. The third option is modifying the shape of the lumen within the extreme distal end of the cartridge where the lumen is smallest so that it is neither circular nor oval. Each or all of these modifications may be incorporated into a single cartridge.

An intraocular lens insertion device which dramatically reduces the possibility that a plunger damages an intraocular lens, and which can safely and surely insert an intraocular lens into an eye is provided. An intraocular lens insertion unit comprises a lens disposing part for disposing an intraocular lens, a plunger for pushing out the intraocular lens disposed at the lens disposing part, a transition part for deforming the intraocular lens pushed out by the plunger, and a nozzle for ejecting the deformed intraocular lens. The plunger has a lens contact part for contacting the outer edge of the intraocular lens, and a protrusive part for pushing the lens contact part downward the intraocular lens by the deformation of the intraocular lens, both lens contact part and protrusive part are provided at the leading end of the plunger.

The invention is directed to an intraocular lens having an optical body, two haptic elements and first and second sets of a plurality of ropes corresponding to respective ones of the first and second haptic elements. The ropes are secured to the optical body and to the haptic element and have a severing sequence. The haptic elements each have a compressed state, a partly compressed state and an uncompressed state. In the compressed state, the first rope of the severing sequence is configured to deform the haptic element in a direction toward the optical body as a result of which the first rope is under a tensile stress and the rest of the ropes are stress-free and, by the ropes being severed successively in the severing sequence, the haptic element can be brought firstly to the partly compressed state. All the ropes are severed in the uncompressed state.

A semi-loaded intralocular lens injector device and related methods are described. In some embodiments, an intraocular lens is stored in a non-deformed configuration in a cassette separate from the injector device. When the cassette is inserted into a cavity of the injector device, a projection extending into the cavity deforms the intraocular lens into a predetermined configuration.

An intraocular support system is provided. This apparatus provides support when natural support structures are absent, diminished, or damaged. The apparatus may include a base that inserts into the internal scleral wall in the sulcus in an arched fashion that does not perforate the external scleral wall. It may be self-retaining with barb protrusions. It may include stabilizers that rest on the ciliary body. The base may include a modular junction that allows interchangeable extensions. The extensions may provide varied functions including intraocular lens support, capsular bag support, and accommodation. It may be applied in acute surgical conditions or in planned cases.
