Abstract: A multi-component intraocular lens implanted in an optical system of a human eye, includes one or more removable components. One component acts as a base lens and another component acts as the front lens. A front lens formed from two integral optical portions may be milled with tabs to establish an axial orientation of the front lens. The front lens may have a different diameter than the base lens. The base lens may have sharp or angled edges and the front lens may have rounded edges. Non-optical portions of the intraocular lens system may be manufactured from a material that is capable of releasing a pharmacological agent. A flange may be fused with the base lens to allow the front lens to engage with the base lens.

Abstract: A method of correcting optical aberrations and abnormalities within the optical system of an eye having an intraocular lens implanted therein. The method includes the step of measuring and determining the extent of the aberrations and abnormalities. Removing at least one removable component of the intraocular lens. Modifying at least one surface of the removable component to eliminate or correct the aberrations and abnormalities. Reinserting the modified removable component within the intraocular lens in the optical system through a same wound formed to originally implant the intraocular lens.

Abstract: The compound intraocular lens ("CIOL") of the present invention includes a preexisting lens within the eye (which can be either of the crystalline lens of the eye, a conventional IOL or a base lens of a multi-component IOL) used as a platform for support (i.e., the "support lens") a cap situated on the support lens, and a sandwich lens which is sandwiched between the support lens and the cap lens. Utilizing a pre-existing implanted IOL or the crystalline lens of the eye, a surgeon can modify a patient's vision characteristics merely by utilizing the cap and sandwich lenses in conjunction with the pre-existing implanted IOL or the crystalline lens of the eye.
