Abstract
An IOL that is free of glare and the halo effect associated with conventional IOLs and a method for using the same is provided. The IOL is adapted for implantation into an eye, in place of or in addition to the natural lens of the eye, to adjust a refractive power of an eye. The IOL includes at least one lens portion and a light-absorbing material. The lens portion has first and second surfaces and a perimeter connecting the first and second surfaces which extends entirely about the lens portion. The first and second surfaces can have any suitable shape to provide the lens portion with a suitable refractive power. The light-absorbing material is disposed to absorb light propagating in a direction towards the perimeter to thus eliminate glare and the halo effect caused by such light. One or more haptics which include a light absorbing material can be attached to the lens portion for mounting the IOL in the eye. The light absorbing material of the haptics absorbs light impinging on the haptics to further eliminate glare and the halo effect.
