Refractive intraocular implant lens and method

Abstract

A refractive intraocular lens ( 104 ) and method of locating the lens within the eye and attaching the lens to the iris. The refractive intraocular lens ( 104 ) may be attached via a staple ( 230 ), a fastener ( 312 ), anchor ( 412 ) or by the tip of the haptic ( 118 ). The intraocular lens ( 104 ) works in combination with the human crystalline lens to treat conditions selected from the group consisting of myopia, hyperopia and astigmatism.

That which is claimed is: 
     
         1 . A refractive intraocular lens for insertion and fixated in an eye with a human crystalline lens, comprising:
 an optic for producing a preselected optical effect for treatment of presbyopia in conjunction with myopia or hyperopia, the optic having an anterior side, a posterior side and an outer peripheral edge;   at least one haptic comprising a posterior side and an anterior side, the at least one haptic incorporating a riser and extending outward from the optic, and wherein the posterior side of the at least one haptic is adapted to be disposed on an anterior side of an iris between a sphincter muscle and a dilator muscle of the iris; and   at least one iris connector adapted to fasten to at least a portion of the at least one haptic and such that the at least one iris connector extends beyond the posterior side of the at least one haptic, to penetrate the anterior side of the iris to fixate the at least one haptic to the anterior side of the iris so as not to interfere with normal sphincter muscle and dilator muscle functions of the iris.   
     
     
         2 . The refractive intraocular lens of  claim 1 , wherein the iris connector is constructed and arranged to penetrate less than the entire thickness of the iris. 
     
     
         3 . The refractive intraocular lens of  claim 1 , wherein the optic is selected for the treatment of conditions selected from the group consisting of myopia, hyperopia, astigmatism and presbyopia. 
     
     
         4 . The refractive intraocular lens of  claim 1  wherein the at least one haptic comprises a plurality of haptics, the plurality of haptics extending outward from the optic and being spaced apart from each other, and wherein at least one of the plurality of is configured to be placed in contact with a surface of the iris. 
     
     
         5 . The refractive intraocular lens of  claim 1  wherein the at least one haptic is made from a flexible material. 
     
     
         6 . The refractive intraocular lens of  claim 1 , wherein the at least one haptic comprising at least one riser for maintaining the optic in spaced relation from the iris. 
     
     
         7 . The refractive intraocular lens of  claim 1 , wherein the at least one iris connector is selected from the group consisting of: staple, screws, barbed hooks, or anchors. 
     
     
         8 . The refractive intraocular lens of  claim 1 , wherein the optic is foldable and adapted to be inserted into the eye with incision techniques which reduce trauma to tissues of the eye. 
     
     
         9 . The refractive intraocular lens of  claim 1 , wherein the at least one iris connector comprises at least one flexible staple separate from the at least one haptic, the at least one flexible staple operatively associated with the at least one haptic and being adapted to extend beyond the posterior side of the at least one haptic to penetrate the anterior side of the iris to fixate the at least one haptic to the anterior side of the iris to attach the refractive intraocular lens to the anterior side of the iris. 
     
     
         10 . The refractive intraocular lens of to  claim 9 , wherein the at least one flexible staple is adapted to be deformed and when placed in contact with the surface of the iris, the at least one flexible staple penetrates into the iris, thus adapted to attach the refractive intraocular lens to the iris and fixing the position of the refractive intraocular lens thereon.
