Intraocular lens holding devices

Abstract

Devices for implanting inside an eye and for holding an intraocular lens (IOL) are presented; the device being operable to rotate the IOL, around an optical axis of the IOL, by absorbing energy from a remote energy source; the device comprises: a stator portion configured to be fixedly positioned inside the lens capsule of the eye; a rotor portion configured to be fixedly attached to the IOL; and a movement system operable to cause rotation of the rotor portion and the IOL, the movement system comprises a plurality of actuators and at least one interaction region associated with the plurality of actuators, the plurality of actuators comprise at least two actuators operable to cause the rotation of the rotor portion and the IOL in each of the clockwise and counterclockwise angular directions, the plurality of actuators and the at least one interaction region being aligned such that at each given moment in time, each actuator of the plurality of actuators is aligned differently with respect to the interaction region associated therewith, and is configured, when being activated by said remote energy source, to engage with the associated interaction region to cause the IOL to rotate with a different incremental rotation having either a different angular distance or a different angular direction; the device may comprise a protective shielding assembly that seals the moving parts from invading biological tissue.
