Title:
負の異常光視症を軽減するように設計された周辺領域を持つ眼内レンズ
Document Type and Number:
Japanese Patent JP2010525884
Kind Code:
A
Abstract:
In one aspect, the invention provides an intraocular lens (IOL) that includes an optic and a peripheral optical flange that surrounds the optic. The optic can form an image of a field of view on the IOL user's retina and the peripheral flange can inhibit dysphotopsia. By way of example, the peripheral flange can include at least one textured surface that is adapted to receive peripheral light rays entering the eye at large visual angles so as to cause their scattering in order to inhibit dysphotopsia, e.g., by preventing the formation of a secondary peripheral image or scattering some light to a shadow region between such a secondary image and an image formed by the IOL.
