Optimal iol shape factors for ophthalmic lenses

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.
