Abstract:
In one aspect, the present invention provides a method of correcting vision, which comprises determining a residual accommodation exhibited by a natural, crystalline lens of an eye, and selecting a multifocal intraocular lens (IOL), which exhibits a far-focus optical power (e.g., in a range of about −15 to about +50 Diopters (D)) and an add power (e.g., in a range of about 1 D 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 accommodation such that a combination of the IOL and the natural lens provides a visual contrast greater than about 10% at a spatial frequency of about 20 cycles/degree for viewing objects at a distance greater than about 30 cm from the eye.
