Abstract

An ophthalmic device includes an optic including an optic axis and a haptic structure coupled with the optic. The haptic structure includes an inner ring comprising a plurality of hinges such that portions of the inner ring reside at different radii from the optic axis. The haptic structure further includes a first loop extending from the inner ring and having two points of connection to the inner ring and a second loop extending from the inner ring and having two points of connection to the inner ring. The second loop is oriented opposite the first loop.

Claims (12)

1. An ophthalmic device comprising:

an optic including an optic axis; and

a haptic structure coupled with the optic, the haptic structure comprising:

an inner ring comprising a plurality of members and a plurality of hinges connecting the plurality of members, whereby a first portion of the plurality of members extends outward from the optic and a second portion of the plurality of members extends inward toward the optic such that portions of the inner ring reside at different radii from the optic axis;

a first loop extending from the inner ring and having at least two unique points of connection to the inner ring; and a second loop extending from the inner ring and having at least two unique points of connection to the inner ring, the second loop oriented opposite the first loop.

2. The ophthalmic device of claim 1 , further comprising a plurality of struts each extending substantially radially outward from the optic and connecting the optic and the inner ring.

3. The ophthalmic device of claim 2 , wherein the plurality of struts are spaced evenly around the periphery of the optic.

4. The ophthalmic device of claim 1 , wherein each of the plurality of hinges subtends a first angle, the first angle of each of the plurality of hinges being substantially equal.

5. The ophthalmic device of claim 1 , wherein:

the first loop subtends a first angle;

the second loop subtends a second angle; and

the first angle and the second angle have substantially the same value, the value being greater than or equal to ninety degrees.
