An intraocular lens system for implantation in the eye (102) to modify the lens system of the eye (102) having the cornea and the natural or existing artificial lens in the eye (102), and a method for using the same. The system and method comprises a lens having a high minus portion, adapted to be implant in the eye (102) to create a lens system that functions as a teledioptic lens system which, when used without an external lens, provides unmagnified and peripherally unrestricted vision and which, when used with an external lens, provides magnified and peripherally restricted vision to correct for macular degeneration. The lens can be attached to the iris, to a portion of the iris that was removed by iridectomy, or can be implanted in the cornea. The lens can also include a plus portion that is surrounded by high minus portion. The high minus portion is preferably about one to about three millimeters in diameter, and can have an outer perimeter with no surrounding material or can be surrounded by a plus, minus or toric lens. |
