Intraocular lens for correcting presbyopia

Abstract

The present invention relates to an intraocular lens. The intraocular lens includes a lens having an opening therein and an ocular system capable of being inserted into the opening after implantation into an eye. Wherein the first lens is adapted to project a first image onto the retina and the second lens is adapted to project a second image onto the retina.

1 . An intraocular lens, comprising: 
 a lens having an opening therein; and    an ocular system capable of being inserted into said opening after implantation into an eye;    wherein said first lens is adapted to project a first image onto the retina and said second lens is adapted to project a second image onto the retina.    
     
     
         2 . An intraocular lens according to  claim 1 , wherein 
 said lens has a slit extending from said opening radially outwardly.    
     
     
         3 . An intraocular lens according to  claim 1 , wherein 
 said ocular system includes a negative lens and a positive lens positioned in series.    
     
     
         4 . An intraocular lens according to  claim 1 , wherein 
 said ocular system is configured such that it frictionally fits with said opening.    
     
     
         5 . an intraocular lens according to  claim 1 , wherein 
 said ocular system is configured to be a telescopic lens system.    
     
     
         6 . An intraocular lens according to  claim 1 , wherein 
 said lens is adapted to be adjusted after implantation.    
     
     
         7 . An intraocular lens according to  claim 6 , wherein 
 said lens is at least partially formed of a silicone polymer with loose monomers.    
     
     
         8 . An intraocular lens according to  claim 1 , wherein 
 said opening is substantially in the center of said lens.    
     
     
         9 . An intraocular lens, comprising: 
 a lens having a peripheral portion substantially surrounding an opening, a slit extends from said opening and into said peripheral portion; and    a telescopic system configured to frictionally fit into said opening.    
     
     
         10 . An intraocular lens according to  claim 9 , wherein 
 said telescopic system includes a negative lens and a positive lens positioned in series.    
     
     
         11 . An intraocular lens according to  claim 9 , wherein 
 said lens is adapted to be adjusted after implantation.    
     
     
         12 . An intraocular lens according to  claim 11 , wherein 
 said lens is at least partially formed of a silicone polymer with loose monomers.    
     
     
         13 . An intraocular lens according to  claim 9 , wherein 
 said opening is substantially in the center of said lens.    
     
     
         14 . An intraocular lens according to  claim 9 , wherein 
 said first lens is adapted to project a first image onto the retina and said second lens is adapted to project a second image onto the retina.    
     
     
         15 . A method of altering vision of an eye, comprising the steps of 
 inserting a lens into the eye, said lens having an opening therein and adapted to project a first image on the retina,    inserting an ocular system in said opening, said ocular system adapted to project a second image on the retina, and    applying energy to said lens to alter the shape thereof.    
     
     
         16 . A method according to  claim 15 , wherein 
 said step of inserting a lens into the eye includes inserting a lens having a slit extending from said opening in the direction of a peripheral portion of said lens.    
     
     
         17 . A method according to  claim 15 , wherein 
 said step of inserting a lens into the eye includes inserting a lens at least partially formed of a silicone polymer with loose monomers.    
     
     
         18 . A method according to  claim 17 , wherein 
 said step of applying energy to said lens includes irradiating said lens to polymerize a portion thereof.    
     
     
         19 . A method according to  claim 15 , wherein 
 said step of inserting an ocular system in said opening includes frictional fitting said ocular system in said opening after said lens has been inserted into said eye.    
     
     
         20 . A method according to  claim 15 , wherein 
 said step of inserting an ocular system in said opening includes an ocular system configured to be a telescopic lens system.
