An intraocular lens system comprising at least one intraocular lens having an anterior surface and a posterior surface, wherein at least one surface of the lens is aspherical to provide for a continuum of retinal images to be focused at the retina in an area between two retinal eccentricities. The system may include an anterior light-converging intraocular lens 16 for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens 17 for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein one or both surfaces of the anterior lens and/or one or both surfaces of the posterior lens are aspherical.
