An intraocular lens system includes a primary intraocular lens configured to correct vision in a patient, and a supplemental intraocular lens configured to modify the correction provided by the primary intraocular lens. The supplemental intraocular lens, which is substantially completely diffractive, is preferably ultrathin. The two lenses may be connected to, or separate from, one another. The supplemental intraocular lens may be implanted at the same time as the primary intraocular lens, or added later.
