Patent number: 8529623Abstract: A method of designing a multifocal ophthalmic lens with one base focus and at least one additional focus, capable of reducing aberrations of the eye for at least one of the foci after its implantation, comprising the steps of: (i) characterizing at least one corneal surface as a mathematical model; (ii) calculating the resulting aberrations of said corneal surface(s) by employing said mathematical model; (iii) modelling the multifocal ophthalmic lens such that a wavefront arriving from an optical system comprising said lens and said at least one corneal surface obtains reduced aberrations for at least one of the foci. There is also disclosed a method of selecting a multifocal intraocular lens, a method of designing a multifocal ophthalmic lens based on corneal data from a group of patients, and a multifocal ophthalmic lens.Type: GrantFiled: January 28, 2011Date of Patent: September 10, 2013Assignee: AMO Groningen B.V.Inventors: Patricia Ann Piers, Hendrik Albert Weeber, Sverker Norrby

Publication number: 20090234448Abstract: An ophthalmic lens for providing enhanced or extended depth of focus includes an optic having an aperture disposed about an optical axis. The optic includes a first surface having a first shape and an opposing second surface having a second shape, the first and second surfaces providing, a base power and, in some embodiments an add power. The optic further includes an extended focus mask disposed upon at least one of the first shape and the second shape that is configured to provide the enhanced or extended depth of focus for one or more foci of the optic, as compared to a similar optic not having the extended focus mask.Type: ApplicationFiled: May 13, 2008Publication date: September 17, 2009Applicant: Advanced Medical Optics, Inc.Inventors: Hendrik Albert Weeber, Patricia Ann Piers, Carina R.

Patent number: 6830332Abstract: According to the invention the ophthalmic lens further comprises a refractive part comprising at least one surface, which is configured to compensate a passing wavefront at least partly for at least one type of monochromatic aberration introduced by at least one of the optical parts of the eye. Said diffractive part is capable of compensating a passing wavefront at least partly for chromatic aberration introduced by at least one of the optical parts of the eye. Furthermore said refractive and diffractive parts together contribute to a required power of the lens.Type: GrantFiled: April 10, 2002Date of Patent: December 14, 2004Assignee: Advanced Medical Optics, Inc.Inventors: Patricia Ann Piers, Hendrik Albert Weeber
