Intraocular lens having hinged haptic structures

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.

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 hinges 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 points of connection to the inner ring; and 
 a second loop extending from the inner ring and having at least two 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 connection 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 the plurality of hinges subtends a first angle, the first 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.
