Three-lens intraocular lens system

A three-lens intraocular lens (IOL) system, comprising:

• a first, anterior lens;
• a second, posterior lens rigidly connected to the first lens by at least one rigid member such that the second lens is a fixed distance, d from the first lens along an axis;
• a third, center, moveable lens positioned between the first lens and the second lens and adapted to move linearly along the axis anteriorly in a direction of the first lens or posteriorly in a direction of the second lens to change an optical power of the system;
• and
• an articulating actuator that contacts the moveable lens and a capsular bag of an eye when the IOL system is implanted in the capsular bag, the articulating actuator adapted to move the moveable lens linearly along the axis;
• wherein a distance t1 between the center of the moveable lens and the first lens along the axis changes by between 0.1 mm and 0.3 mm, inclusive, in response to a movement of the articulating actuator.

• an articulating actuator that contacts the moveable lens and a capsular bag of an eye when the IOL system is implanted in the capsular bag, the articulating actuator adapted to move the moveable lens linearly along the axis, the articulating actuator comprising:
• a lever point;
• a first arm located between the lever point and the moveable lens and adapted to contact the moveable lens;
• a contact adapted to contact an interior surface of the capsular bag when the IOL system is implanted in the eye;
• and
• a second arm located between the contact and the lever point;
• wherein the first and second arm form an angle θ;
• and
• wherein the articulating actuator is adapted such that the first arm pivots around the lever point to form a more acute angle with the second arm when the capsular bag tightens and to move the moveable lens posteriorly towards the second lens as a result.
