Abstract
An intraocular lens (IOL) configured to support a first optic for functioning as a single lens IOL and configured to support a second optic for functioning as a dual optic IOL. The base includes a first optic for providing a base power. A recess in an anterior rim of the base is configured for positioning a radial extension of a second optic. The geometry of the recess is configured to securely couple to the radial extension to prevent rotation of the second optic relative to the base and prevent tilting of the second optic relative to an optic axis.
