Patent number: 9636016Abstract: Example eye-mountable devices and methods for placing a flexible ring containing electronics in an eye-mountable device are described. A method may involve forming a first polymer layer, which defines a posterior side of an eye-mountable device. Further, the method may involve positioning a ring-shaped structure on the first polymer layer in a predetermined rotational orientation, wherein the ring-shaped structure comprises a sensor configured to detect an analyte. Still further, the method may involve forming a second polymer layer over the first polymer layer and the ring-shaped structure, such that the ring-shaped structure is fully enclosed by the first polymer layer and the second polymer layer. The second polymer layer defines an anterior side of the eye-mountable device. The method may also involve forming a channel through the second polymer layer based on the predetermined rotational orientation, such that the sensor is configured to receive the analyte via the channel.Type: GrantFiled: January 25, 2013Date of Patent: May 2, 2017Assignee: Verily Life Sciences LLCInventors: James Etzkorn, Harvey Ho, Jeffrey George Linhardt

Patent number: 9465233Abstract: Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include an inner optic portion configured to be disposed over the optical region of the cornea and having a central portion disposed between an anterior portion and a posterior portion. The inner optic portion is configured to at least partially diverge from the shape of the cornea to provide at least one lenticular volume between a posterior surface of the inner optic portion and the cornea. The central portion may be characterized by a thickness from 50 ?m to 900 ?m and a modulus form 20 MPa to 1500 MPa.Type: GrantFiled: November 4, 2014Date of Patent: October 11, 2016Assignee: NexisVision, Inc.Inventors: Eugene de Juan, Jr., Cary J.

Patent number: 8678584Abstract: Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include a deformable inner portion and a deformable peripheral portion. When disposed over the optical region of an eye, the inner portion is configured so that engagement of the posterior surface against the eye deforms the posterior surface so that the posterior surface has a shape diverging form the refractive shape of the epithelium when viewing with the eye through the ophthalmic lens. The rigidity of the inner portion is greater than the rigidity of the peripheral portion and the ophthalmic lenses are configured to allow movement relative to the eye upon blinking of the eye and to be substantially centered on the optical region of the cornea following the blinking of the eye. Methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses are also disclosed.Type: GrantFiled: June 26, 2013Date of Patent: March 25, 2014Assignee: NexisVision, Inc.Inventors: Eugene de Juan, Jr., Cary J.

Publication number: 20130035760Abstract: A lens in accordance with the present invention includes an accommodating cell having two chambers with at least one chamber filled with optical fluid with the refractive index matching the refractive index of the accommodating element separating them. The accommodating element has a diffractive surface with surface relief structure that maintains its period but changes its height due a pressure difference between the chambers to redirect most of light that passes through the lens between different foci of far and near vision. The invention also includes a sensor cell that directly interacts with the ciliary muscle contraction and relaxation to create changes in pressure between the accommodating cell chambers that results in changing surface relief structure height and the lens accommodation.Type: ApplicationFiled: September 28, 2011Publication date: February 7, 2013Inventor: Valdemar PORTNEY

Patent number: 8246167Abstract: In accordance with exemplary embodiments of the present invention, an eye is presented with a therapeutic optical structure (e.g., corneal reshaping or by way of a contact lens) that focuses the peripheral image field in at least one meridian in front of the mid peripheral retina. In general, the therapeutic optical structure places the peripheral image field with reference to the retina in the direction and amplitude that growth is needed in order that the emerging myopia would be regulated. In accordance with exemplary embodiments of the present invention, an eye is presented with a therapeutic optical structure that further produces a central retinal image that is focused on the central retina in at least one meridian so as to not reshape the central cornea.Type: GrantFiled: December 17, 2009Date of Patent: August 21, 2012Assignee: CRT Technology, Inc.Inventors: Jerome A.
