Implantable lenses can correct vision at near, middle, and far distances by replacing the eye's natural or damaged lens.

Previously, that 20/20 equivalence often was not attained in the intermediate distance," notes McCulley, who directs the Center for Research in Age-Related Macular Degeneration.
