Accommodating intraocular lens system with separation member

An accommodating intraocular lens, comprising:

• an anterior portion having an anterior viewing element comprising an optic having refractive power;
• a posterior portion having a posterior viewing element, said viewing elements positioned to move relative to each other along an optical axis in response to action of the ciliary muscle of the eye;
• at least one of the anterior and posterior portions having at least one separation member with a contact surface, said at least one separation member configured to prevent contact between said anterior viewing element and said posterior viewing element by inhibiting relative movement of said anterior and posterior portions toward each other beyond a minimum separation distance;
• wherein said contact surface contacts an opposing surface of said intraocular lens over a contact area when said portions are at said minimum separation distance, at least one of said surfaces having an adhesive affinity for the other of said surfaces, said contact area being sufficiently small to prevent adhesion between said surfaces when said anterior portion and said posterior portion are separated by said minimum separation distance.
