Publication number: 20100217386Abstract: An IOL having an optic and a peripheral stabilizing ring. The optic and the ring are connected by a flexible bridge. An area on the ring coinciding with a feature on the optic helps to locate the optic within the ring in an unstressed state until the capsular bag collapses and locks the optic into place.Type: ApplicationFiled: May 6, 2010Publication date: August 26, 2010Inventor: James M.

Patent number: 7763069Abstract: An intraocular lens for insertion into the capsular bag of an eye contains an optic, an outer periphery, and an outer support structure. The optic has a periphery and centered about an optical axis. The outer periphery is disposed about the optic and configured to engage an equatorial region of the capsular bag of an eye. The outer support structure is disposed along the periphery and spaced from the optic with voids outer support structure and the optic. The intraocular lens further comprises a first intermediate member and a weakened region disposed along the outer periphery between the outer support structure and the first intermediate member. The first intermediate member operably couples the optic and the outer support structure. The weakened region is attached to, and configured to provide relative motion between, the outer support structure and the first intermediate member in response to the ciliary muscle of the eye.Type: GrantFiled: December 28, 2005Date of Patent: July 27, 2010Assignee: Abbott Medical Optics Inc.Inventors: Daniel G. Brady, Arlene E. Gwon
