Patent number: 8794759Abstract: The invention is directed to a contact lens design and methods of manufacturing, fitting and using such lenses. The contact lens may be designed for use in a corneal refractive therapy (CRT) program. The lens provides a design which allows proper fitting of a patient, whether for corrective contact lenses or for a CRT program. Due to the rational design of the lenses according to the present invention, a minimal number of lens parameter increments can be identified to cover the range of common corneas. It is therefore possible to provide pre-formed lens buttons or blanks which are easily formed into a final design, thereby simplifying and speeding up the treatment process. Further, any adjustment of the lens design which may be required based upon trial fitting or the like, is easily envisioned and implemented by the fitter.Type: GrantFiled: September 23, 2011Date of Patent: August 5, 2014Assignee: CRT Technology, Inc.Inventors: Jerome A. Legerton, William E. Meyers

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. Legerton, William E. Meyers

Patent number: 8201941Abstract: This invention relates to methods of shaping the anterior surface of the eye for controlling the progression of refractive error of the eye, in particular, myopia. The method employs the fitting of orthokeratology lenses having a precisely shaped posterior surface adapted to accurately shape the peripheral region of the eye. The method includes the steps of assessing central and peripheral refractive error parameters for the eye, determining the optimal anterior surface profile for the eye, including at both the optical centre of the cornea and at a selected optical periphery of the cornea, which would result in a desired refractive correction to achieve good vision for the eye and the desired peripheral refraction (curvature of field) for the eye for controlling progression of myopia.Type: GrantFiled: July 31, 2007Date of Patent: June 19, 2012Inventors: Jennifer Denise Choo, Arthur Ho, William E. Meyers, Fabian Conrad, Brien Anthony Holden

Patent number: 8082824Abstract: The present invention is directed toward the design of a holding apparatus which allows contact lens lathes to hold contact lens buttons during the contact lens manufacturing process. The holding apparatus functions to hold lenses manufactured from a different sized stock than what the lens manufacturing equipment is designed to hold. In general the holding apparatus has a circular portion having a mating surface on a one side and a cylindrical protrusion extending from the other side. A contact lens lathe can hold the cylindrical protrusion of the holding apparatus while the mating surface mates with a surface on a contact lens button. The lens button and holding apparatus surfaces can be modified to allow more efficient machining of the lens buttons.Type: GrantFiled: April 23, 2009Date of Patent: December 27, 2011Assignee: Paragon Vision Sciences, Inc.Inventor: William E.

Patent number: 7905595Abstract: A system and method for treating and preventing loss of visual acuity. The system comprises a vision correcting lens, such as a contact lens, having a material with a regular pattern of orientation of polarizable molecular bonds, so as to create a birefringent effect. Off-axis light rays are refracted through the contact lens so as to focus in front of the retina, whereas on-axis light rays pass through the contact lens without refraction, such that their focal point on the fovea is unaltered. In an exemplary embodiment, a contact lens of the present invention is capable of independently altering the refractive state of the eye in relation to fovea and peripheral retina so as to simultaneously correcting visual acuity while minimizing the signal for axial growth and hence myopic progression.Type: GrantFiled: April 28, 2008Date of Patent: March 15, 2011Assignee: CRT Technology, Inc.Inventors: William E. Meyers, Hemann Neidlinger

Patent number: 7828432Abstract: A hybrid contact lens includes a substantially rigid center portion and a substantially flexible skirt portion connected to the center portion. The skirt portion is formed using xerogels compatible with diluents comprising at least one selected from polylactic acid, polyglycolic acid, lactide, glycolide, a polyacetal, a cyclic acetal, a polyketal, a cyclic ketal, a polyorthoester, a cyclic orthoester, di-t-butyl-dicarbonate, tris(trimethylsilyl)amine, and 2,2,2-trifluoroacetamide. These diluents are formulated to function as a stand-in for water in the xerogel polymer, allowing the xerogel to form and bond to the rigid center portion in its fully expanded state. Upon hydration of the hybrid lens, substantially little dimensional change, and thus substantially little distortion, is obtained in the skirt portion.Type: GrantFiled: May 25, 2007Date of Patent: November 9, 2010Assignee: Synergeyes, Inc.Inventors: William E.
