Patent number: 8684527Abstract: An eye simulation system for testing wavefront sensor systems, the eye stimulation system comprising a housing having a chamber with an opening for allowing light to enter said chamber, a fluid located in the chamber, said fluid having a known index of refraction, a lens positioned relative to said housing such that light entering the opening of the chamber passes through said lens, and a rotatable imaging surface positioned in said chamber such that light passing through said lens propagates through said fluid and is incident on said rotatable imaging surface.Type: GrantFiled: January 27, 2012Date of Patent: April 1, 2014Assignee: Essilor International (Compagnie Generale d'Optique)Inventors: Laurence Warden, Andreas W. Dreher, Gary D. Mills, Shui T. Lai, William G. Foote, David G. Sandler, Keith J. Dillon

Patent number: 7909461Abstract: Diagnostic instruments, systems and methods for performing measurements on eyes are disclosed. In one embodiment of the instrument, a left ocular is disposed in a portion of a left visual path for the left eye, the left ocular positioned to permit the left eye to view a target, a right ocular is disposed in a portion of a right visual path for the right eye, the right ocular positioned to permit the right eye to view a target. The instrument can also include a wavefront sensor disposed on a translation stage, the wavefront sensor having an optical path to an imaging sensor, the translation stage being movable to position the optical path of the wavefront sensor in alignment with the portion of the left visual path in a first state and in alignment with the portion of the right visual path in a second state. One or more light sources are optionally provided for propagating light along a least part of the left and right visual paths to illuminate the left and right eyes.Type: GrantFiled: September 16, 2008Date of Patent: March 22, 2011Assignee: Opthonix, Inc.Inventors: Laurence Warden, Andreas W. Dreher, Gary D. Mills, Shui T. Lai, William G. Foote, David G. Sandler, Keith J. Dillon
