Compound intraocular lens

A multi-component intraocular lens systems for an eye, comprising:

• a base intraocular lens, for positioning in the eye, said base intraocular lens having a radius and a circumference and including a first plurality of flanges selectively interspersed around said circumference, and a first plurality of projections for holding said multi-component intraocular lens system in place in the eye;
• a cap lens situated on said base lens, said cap lens having a radius and a circumference and including a second plurality of flanges, a first subset of said second plurality of flanges projecting upwards from said cap lens and a second subset of said second plurality of flanges projecting downwards from said cap lens, both of said first and second subsets of said second plurality of flanges being selectively interspersed around said circumference of said cap lens;
• and
• a sandwich lens, fixed to an anterior surface of said cap lens, said sandwich lens having a radius and a circumference and including a third plurality of flanges projecting downwards from said sandwich lens and being oriented in such a manner as to interlockingly engage with said second plurality of flanges so as to securely hold said sandwich lens in the correct orientation for appropriate correction of vision of said eye.
