Abstract

An artificial lens adapted for use in an eye having a macula is shown. The artificial lens is adapted to be affixed to an eye and has a multifocal optical lens system wherein the principal axis of each lens is eccentric to each other for directing light rays from each image of each lens of the multifocal optical lens system onto a macula of an eye. In the preferred embodiment, the artificial lens includes a first lens having a predetermined diopter power for receiving light rays from a near object and a prism having a preselected diopter power. The prism is positioned on a selected surface of the first lens for directing paracentral light rays from a near object onto a macula of an eye and central light rays to a location superior of the macula. The artificial lens includes a second lens having a predetermined diopter power positioned eccentrically inferior of said first lens for receiving light rays from a distant object and a second prism having a preselected diopter power. The second prism is positioned on a selected surface of the second lens for directing paracentral light rays from a distant object onto a macula of an eye and central light rays to a location inferior of the macula. A method for producing multiple images of an object for an eye is also shown.
