摘要:
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.
摘要(中):
一方面,本发明提供了一种眼内透镜(IOL),其包括光学元件和围绕光学元件的外围光学法兰。 光学元件可以在IOL用户的视网膜上形成视场图像,并且外围法兰可以抑制异位斑。 作为示例,周边凸缘可以包括至少一个纹理表面,其适于以大的视角接收进入眼睛的周边光线,以便使其散射以便抑制异常斑,例如通过防止形成 二次周边图像或将一些光散射到这种二次图像与由IOL形成的图像之间的阴影区域。
