Patent number: 8342684Abstract: A method or process for providing an anti-myopia lens or treatment for a patient's eye with progressive myopia, which involves (in one form) generating biometric data relating to the central and peripheral refractive errors of the eye, optionally together with data relating to the patient's visual or lifestyle needs and the patient's predisposition to progressive myopia. This data is input to a processor or algorithm that generates a basic lens design, a customised design or a program for reshaping the cornea of the eye. The selected modality is applied to the patient and its suitability is assessed with the result of the assessment feedback to the algorithm to generate a refined output design, which is applied to the patient. The process is repeated at intervals to check continued myopia progression and adjust the design of the selected modality after further measurement.Type: GrantFiled: April 28, 2008Date of Patent: January 1, 2013Assignee: The Institute for Eye Research LimitedInventors: Arthur Ho, Klaus Ehrmann

Publication number: 20100195093Abstract: An instrument and method is for characterizing the optical properties of an optical system, such as a lens, another optical device or the human eye, over an optical surface of the optical system. In one example, an incident beam is scanned over the surface of a lens to generate an emergent beam that is divided by a beam-splitter into two portions that are directed to respective two-dimensional detector arrays located at different optical distances from the lens. The detector arrays output the lateral coordinates of the points of incidence of the respective emergent beam portions so that the angle of emergent beam with respect to the optical axis or incident beam can be accurately determined. Determining the variation in the angle of the emergent beam over the surface of the lens allows many important optical characteristics of the lens to be characterized and mapped onto to the surface of the lens.Type: ApplicationFiled: February 14, 2008Publication date: August 5, 2010Applicant: The Institute for Eye Research LimitedInventors: Arthur Ho, Klaus Ehrmann

Patent number: 7665842Abstract: A method and apparatus are disclosed for controlling optical aberrations to alter relative curvature of field by providing optical devices and methods comprising the repositioning of peripheral off-axis focal points relative to the retina to produce stimulus for influencing the progression of refractive error while simultaneously controlling the position of the central focal point near to the retina to provide clear central vision and simultaneously providing zones of controlled peripheral defocus and other optical aberrations to improve peripheral vision for select directions of gaze.Type: GrantFiled: January 11, 2007Date of Patent: February 23, 2010Assignee: Institute for Eye ResearchInventors: Arthur Ho, Earl Leo Smith, III, Padmaja Sankaridurg, Brien Anthony Holden

Patent number: 7556375Abstract: A corneal reshaping by means of a soft contact lens to manipulate tear pressure gradient to produce a dimensional change to the surface profile of the cornea of the wearer to provide at least a temporary change in the refractive state of the eye eliminating the need for other refractive corrections. The contact lens has mechanical properties and/or a geometric shape such that when the lens is fitted to the eye the pressure applied to the eye via the lens will vary in a radial direction between at least one zone of higher pressure and at least one zone of lower pressure so that wearing the lens will over time cause a dimensional change to the surface layer of the cornea.Type: GrantFiled: August 27, 2004Date of Patent: July 7, 2009Assignee: The Institute for Eye ResearchInventors: Patrick Joseph Caroline, Peter Donald Bergenske, Jennifer Denise Choo, Stacy Sanaz Aboutalebi, Simon Rodney Evans, Arthur Ho, Eric Basil Papaspiliotopoulos, Brien Anthony Holden
