A series of ophthalmic lenses, each lens comprising a same spherical power as the other lenses in the set, and a unique cylindrical power, each lens comprising (i) a first toric surface, and (ii) a second surface, at least one of the first surface and the second surface being aspheric in a meridian, the lens having substantially zero spherical aberration for all circular optical zone diameters less than 4 mm. | 04-01-2010 |
| 20110098810 | Aspheric Lenses and Lens Family - In an embodiment, an aspheric IOL for use in a pseudophakic ocular system has no inherent spherical aberration. In an embodiment, an aspheric IOL for use in a pseudophakic ocular system has a controlled amount of inherent negative spherical aberration such that the IOL induces no spherical aberration in a converging wavefront from a cornea passing through the lens. An embodiment of the invention is directed to a family of aspheric IOLs made up of any two or more member aspheric IOLs each having different spherical aberration values and different lens shape factors. A lens constant, such as the well known A-constant, is kept constant throughout the family of lenses. An embodiment of the invention is directed to a multi-component accommodating intraocular lens (A-IOL). In a particular embodiment, the A-IOL introduces substantially no residual spherical aberration to a wavefront incident upon and passing through the A-IOL. | 04-28-2011 |
