| abstract |
In one aspect, the present invention provides an intraocular lens (IOL) that includes an optical element (12) and a peripheral optical flange (14) surrounding the optical element. The optical element forms a field image on the retina of the IOL user, and the peripheral optical flange suppresses abnormal photovision. As an example, the peripheral optical flange includes at least one textured surface that receives ambient rays incident on the eye at a large viewing angle and scatters those ambient rays, for example, Abnormal photovision by inhibiting the formation of secondary images or by scattering some light into shadow areas between such secondary images and the image formed by the IOL Suppress. |
