In one aspect, the present invention provides a method of correcting vision,which comprises determining a residual accommodation exhibited by a natural,crystalline lens (34) of an eye (32), and selecting a multifocal intraocularlens (IOL) (20, 36), which exhibits a far-focus optical power (e.g., in a rangeof about -15 to about +50 Diopters (D) ) and an add power (e.g., in a range of aboutID to about 4 D), for implantation in the eye while retaining the natural lens.The add power of the IOL is selected as a function of the residual accommodationsuch that a combination of the IOL and the natural lens provides a visual contrastgreater than about 10% at a spatial frequency of about 20 cycles/degree for viewingobjects at a distance greater than about 30 cm from the eye.
