Provided is an intraocular lens (1), formed from a capsular tension device (10), and an elastically deforming optical part (20). The capsular tension device (10) further comprises: a forward support part (11) which is disposed in a state of contacting the inner face of the anterior capsule; an aft support part (12) which is disposed aft of the forward support part (11) in a state of contacting the inner face of the posterior capsule while facing the forward support part (11); and a coupling part (13) which couples the forward support part (11) and the aft support part (12) in a state of having a bias in the direction of separation of the forward support part (11) and the aft support part (12). By the bias of the coupling part (13), the forward support part (11) presses the inner face of the anterior capsule, and the aft support part (12) presses the inner face of the posterior capsule. The curvature of the optical part (20) at a central part (21) changes in conjunction with movement of the coupling part (13) which either brings the forward support part (11) and the aft support part (12) into proximity or separates same in accordance with the movement of the lens capsule. |
