<p>The present invention provides an ophthalmic lens (e.g., an intraocular lens)(10) having an optic (12) with an anterior surface and a posterior surface (16), which exhibits a shape factor (defined as a ratio of the sum of the anterior andposterior curvatures to the difference of such curvatures) in a range of about-0.5 to about 4. In a related aspect, the shape factor of the optic lies in a rangeof about 0 to about 2. The above shape factors give rise to a plurality of differentlens shapes, such as concave-convex, plano-convex and plano-concave .</p> |
