1. A method of implanting lens device for treatment of an eye, the method comprising:
forming a capsulorhexis in a capsular bag of an eye;
inserting an intraocular lens device in the eye, the intraocular lens device comprising:
(i) a lens body having an optical axis, the lens body comprising:
a first membrane comprising a first perimeter region and a central, accommodating surface configured to outwardly bow;
a static element having a second perimeter region, the static element positioned opposite the first membrane;
a shape deformation membrane extending along an arc of the lens body and configured to undergo displacement relative to the first perimeter region of the first membrane; and
a fixed volume of optical fluid,
wherein an inner surface of the first membrane, an inner surface of the shape deformation membrane and an inner surface of the static element collectively form a sealed chamber of the lens body that contains the fixed volume of optical fluid;
(ii) a stabilization system comprising a haptic having an inner region positioned posteriorly relative to a posterior region of the lens body and an outer region extending radially outward from the inner region, wherein a channel is formed between a posterior-facing surface of the lens body and an anterior-facing surface of the inner region; and
(iii) a first force translation arm separate and positioned opposite from a second force translation arm, wherein the first and second force translation arms are movable relative to the lens body to cause inward movement of the shape deformation membrane relative to the first perimeter region of the first membrane causing outward bowing in an anterior direction of the central, accommodating surface;
positioning at least an outermost edge of the haptic of the stabilization system inside the capsular bag of the eye;
positioning each of the first and second force translation arms outside the capsular bag so an outer region of each of the first and second force translation arms are able to be in direct contact with a ciliary structure of the eye; and
rotating the intraocular lens device around the optical axis.
