Abstract: 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.

Abstract: 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.

Abstract: Methods and apparatuses are disclosed for improving peripheral vision by positioning the peripheral image points at a pre-determined and precise position relative to the retina to achieve optimal performance according to one or more pre-selected criteria parameters for optimal peripheral vision performance.
