Claim Text:
1. An accommodating intraocular lens for implantation within a capsular bag of an eye, comprising: an optic having an outer periphery and centered about an optical axis; an outer support structure configured to be positioned within the capsular bag of the eye and having a first arcuate arm and a second arcuate arm disposed about the optic and along an outer periphery of the intraocular lens and spaced apart from the optic, the outer periphery of the intraocular lens having a generally oval shape with a major axis and a minor axis, the first arcuate arm having a first proximal end terminating in a first distal end and a second proximal end terminating in a second distal end, the second arcuate arm having a third proximal end terminating in a third distal end and a fourth proximal end terminating in a fourth distal end, the outer support structure including a first void located on the minor axis and between the first distal end of the first arcuate arm and the third distal end of the second arcuate arm such that the first distal end and the third distal end are not in contact with each other and a distance between the first distal end and the third distal end is less than a diameter of the optic along the major axis, the outer support structure including a second void diametrically opposed to the first void across the optic located on the minor axis between the second distal end of the first arcuate arm and the fourth distal end of the second arcuate arm such that the second distal end and the fourth distal end are not in contact with each other and a distance between the second distal end and the fourth distal end is less than a diameter of the optic along the major axis; a first plate-like intermediate member having a proximal end attached to the optic at a portion of the outer periphery of the optic that is positioned on the major axis, and a distal end attached to first and second proximal ends of the first arcuate arm; and a second plate-like intermediate member diametrically opposed to the first plate-like intermediate member, the second plate-like intermediate member having a proximal end attached to the optic at a portion of the outer periphery of the optic that is positioned on the major axis, and a distal end attached to third and fourth proximal ends of the second arcuate arm; wherein the optic is positioned between the first distal end of the first arcuate arm and the second distal end of the first arcuate arm along the minor axis, and the optic is positioned between the third distal end of the second arcuate arm and the fourth distal end of the second arcuate arm along the minor axis, and wherein the intraocular lens further comprises weakened regions disposed along the first arcuate arm and the second arcuate arm, the weakened regions positioned in proximity to the first and second proximal ends of the first arcuate arm and the third and fourth proximal ends of the second arcuate arm, and wherein the weakened regions are configured to provide for relative motion between the first and second distal ends of the first arcuate arm and the third and fourth distal ends of the second arcuate arm during accommodation.
