Single-piece accomodating intraocular lens system

Abstract

There is disclosed an accommodating intraocular lens for implantation in an eye having an optical axis. The lens comprises an anterior portion which in turn comprises an anterior viewing element and an anterior biasing element. The lens further comprises a posterior portion which in turn comprises a posterior viewing element in spaced relationship to the anterior viewing element and a posterior biasing element. The anterior portion and posterior portion meet at first and second apices of the intraocular lens. The anterior portion and the posterior portion and/or the apices are responsive to force thereon to cause the separation between the viewing elements to change. Additional embodiments and methods are also disclosed.

What is claimed is:  
     
         1 . An accommodating intraocular lens, comprising: 
 an anterior portion having an anterior viewing element;    a posterior portion having a posterior viewing element, said viewing elements positioned to move relative to each other along an optical axis in response to action of the ciliary muscle of the eye, wherein said anterior and posterior portions comprise a single piece of material.    
     
     
         2 . The accommodating intraocular lens of  claim 1 , wherein said anterior viewing element comprises an optic having refractive power.  
     
     
         3 . The accommodating intraocular lens of  claim 2 , wherein said posterior viewing element comprises an optic having refractive power.  
     
     
         4 . The accommodating intraocular lens of  claim 1 , wherein said posterior viewing element comprises an optic having refractive power.  
     
     
         5 . An accommodating intraocular lens, comprising: 
 first and second optics, at least one of said optics having refractive power, said optics mounted by an articulated frame to move relative to each other along an optical axis in response to action of a ciliary muscle, said frame formed of a single piece of material.    
     
     
         6 . The accommodating intraocular lens of  claim 5 , wherein at least one of said optics is formed of a material which is different from said material of said frame.
