    摘要: The present invention provides an ophthalmic lens (10,22) including an intraocular lens (TOL) comprising an optic (12) having an anterior surface (14,26) and a posterior surface (16,24), said optic exhibiting a shape factor, defined as a ratio of the sum of the anterior and posterior curvatures to the difference of such curvatures, in a range of - 0.5 to 4. The optic is formed entirely from at least one solid biocompatible material.

    摘要: An IOL (10) is disclosed that includes an anterior surface (14) and a posterior surface (16) disposed about an optical axis (OA), where the posterior surface includes a central region (20) extending to a peripheral region (22). Once the IOL is implanted in a patient's eye, the anterior surface and the central region of the posterior surface cooperatively form an image of a field of view on the retina and the peripheral region of the posterior surface directs at least some light rays 'incident thereon (e.g., via refraction by the anterior surface) to at least one retinal location offset from the image so as to inhibit dysphotopsia.
