Abstract
An improved multi-faceted intraocular lens with a main optical element having a plurality of optical elements. The flexible, thin multi-faceted intraocular lens is made of an optical-grade soft biocompatible material, such as a flexible acrylic material, a hydrophilic material, or a silicone material. The thin, flat, multi-faceted intraocular lens may enable implantation of the lens through an intraocular lens injector having an injection tube with a diameter of approximately 1 mm to 4 mm. The plurality of optical elements each may have the same or differing diopter powers. Additionally, the plurality of optical elements may be aligned to form a multi-focal lens. Further, the optical elements each may be selected from a group consisting of toric elements, aspheric elements, and spherical elements depending upon the type of correction desired. Lastly, the multi-faceted intraocular lens may be effective in the treatment of age-related macular degeneration.
