Intraocular, accommodating lens and methods of use
First Claim
1. An intraocular lens (IOL) for insertion into a capsular bag having a zonular contact region, the IOL comprising:
- a shape changing optical element comprising an anterior surface configured to outwardly bow upon application of a compressive force applied radially inward at an oblique angle to the optical element creating an accommodated shape; and
an accommodating element coupled to the shape changing optical element, the accommodating element comprising;
(i) at least one force transmitting element; and
(ii) a plurality of spaced apart contacting elements each adapted to contact a portion of the zonular contact region; and
(iii) a first linking arm comprising;
a first end obliquely connected to a first region of a first contacting element of the plurality of spaced apart contacting elements where the first contacting element contacts an anterior portion of the capsular bag; and
a second end, and(iv) a second linking arm comprising;
a first end obliquely connected to a second region of the first contacting element where the first contacting element contacts a posterior portion of the capsular bag; and
a second end, wherein the second end of the first linking arm and the second end of the second linking arm are flexibly connected to each other at a point where each respective second end also connects to the force transmitting element,wherein the accommodating element is configured to cooperate with at least one of the ciliary muscle of the mammalian eye, the zonules of the mammalian eye and the vitreous pressure in the eye to transmit the compressive force to the optical element.

Abstract
An intraocular lens is adapted for insertion into a capsular bag having a zonular contact region. The intraocular lens comprises a shape changing optical element and an accommodating element comprising at least one force transmitting element and a plurality of spaced apart contacting elements each adapted to contact a portion of the zonular contact region and transmit compressive displacement radially inward at an oblique angle to the optical element and configured to cooperate with at least one of the ciliary muscle of the mammalian eye, the zonules of the mammalian eye and the vitreous pressure in the eye to effect an accommodating shape and a disaccommodating shape change to the optical element.

12. An intraocular lens (IOL) for insertion into a capsular bag, the IOL comprising:
-
a shape changing optical element comprising; (i) an inner lens portion; (ii) an outer lens body encompassing the inner lens portion and having an anterior center section of reduced thickness surrounding the optical axis of an eye; and (iii) a first equatorial region and a second equatorial region; and an accommodating element disposed between and circumferentially about the optical element, the accommodating element comprising; (i) a first arcuate contacting element adapted to contact a first zonular contact region of the capsular bag; (ii) a first force transmitting element coupled to the first arcuate contacting element at a first end and coupled to the first equatorial region of the shape changing optical element at a second end; (iii) a second arcuate contacting element adapted to contact a second zonular contact region of the capsular bag; (iv) a second force transmitting element coupled to the second arcuate contacting element at a first end and coupled to the second equatorial region of the shape changing optical element at a second end; wherein the accommodating element is configured to maintain the capsular bag in a spherical shape and to transmit a compressive force applied radially inward at an oblique angle to the optical element in cooperation with at least one of the ciliary muscle of the mammalian eye, the zonules of the mammalian eye, and the vitreous pressure in the eye, and wherein the compressive force is transmitted from the first and second arcuate contacting elements through the first and second force transmitting elements to squeeze the first equatorial region and the second equatorial region together causing the center section to outwardly bow creating an accommodated shape change. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
