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.
