Artificial lens including a lens system having eccentric axes for use in an eye having an enlarged pupil and method
First Claim
1. An artificial lens system for producing multiple images of an object for an eye having a natural pupil and a macula, said artificial lens system comprising at least two lenses which are supported in an eye so as to be situated eccentrically from one another and wherein one of said at least one two lenses is adapted to be positioned in the natural pupil and another of said two lenses is adapted to be positioned in an opening formed in the natural pupil such that an optical axis of the one lens is eccentric to an optical axis of another lens for directing light rays from images respectively produced by said two lenses lenses onto the macular of an eye.

Abstract
An artificial lens including a lens system having eccentric axes for in an eye having a macula and an enlarged natural pupil is shown. The artificial lens comprises a first optical lens system and a second optical lens system. The principal axis of each optical lens system is eccentric to each other and the distance between each principal axis is selected to enable the first optical lens system and the second optical lens system to be operable within the enlarged pupil. The lens system of the artificial lens system directs light rays from each image of each lens of the first optical lens system and second optical lens system onto a fovea centralis of the macula of an eye. In the preferred embodiment, a prism having a preselected diopter power is positioned on a selected surface of one of the first optical lens system and second optical lens system for directing light rays from an object onto a fovea centralis of the macula of an eye. A contact lens having an eccentric optical system is also shown.

8. An artificial lens adapted for use in an eye having a macula and an opening formed in a natural pupil comprising
a first optical lens system and a second optical lens system wherein the principal axis of each optical lens system is eccentric to each other and the distance between each principal axis is selected to enable at least one of the first optical lens system and a second optical lens system to be situated within an opening formed in a natural pupil for directing light rays from each image of each lens onto a macula of an eye.

23. An artificial lens adapted for use in an eye having an opening formed in a natural pupil comprising
at least a first lens system and a second lens system having eccentric axes wherein at least one lens system is adapted to be situated in an opening formed in the natural pupil of an eye for producing disparate near and distant macular images.

38. An artificial lens adapted to be located in an opening formed in a natural pupil of an eye wherein the eye has a macula, said artificial lens comprising
a first lens system for receiving and directing light rays from a near object onto the fovea of the macula; - and
a second lens systems positioned inferior in an eccentric arrangement to the first lens system for receiving and directing light rays from a distant object onto the macula;
said first lens system and said second lens system each having a principal axis which are eccentric to each other and the distance therebetween is selected to situate at least one of the first lens system and the second lens system within an opening formed in a natural pupil for directing light rays from each image of each lens onto a macula of an eye.

42. An optical lens for a human eye having a macula and a natural pupil and wherein an opening is formed in the natural pupil comprising
a lens body having an anterior surface and a posterior surface, said lens body including at least two eccentrically arranged lens systems wherein the principal axis of each lens system is eccentric to each other and the distance between each principal axis is selected to enable at least one of the at least two lens systems to be situated within an opening formed in a natural pupil for directing light rays from each image of each lens onto a macula of an eye in a manner to obtain an optical effect for substitution of the loss of accommodation of an eye.
