摘要： 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. Accurate measurement of the shape of the pre-treated eye is important, thereby enabling a corresponding lens profile to be designed or selected so that the treatment process achieves a post-treatment peripheral profile which optimally focuses peripheral rays anteriorly of the retina, thereby controlling the progression of myopia. The invention extends to a lens manufactured so as to optimally treat the peripheral region of the eye.

摘要： An instrument and method for characterising eye-related optical systems, including the live human eye involves scanning an illuminating light beam from a light source and light detector unit from element to element of a beam deflector array of elements arranged laterally across the optical axis of eye. At each successive element the illuminating beam is deflected to form an interrogating beam that is directed into the eye at a peripheral angle that depends upon the lateral location of the deflector element. A return beam is reflected or back-scattered from the cornea and returned via the same deflector element to the light source and detector unit. This allows the interrogating beams to be scanned sufficiently rapidly into the eye to greatly reduce the variation of eye fixation and gaze that accompany other methods of measuring peripheral refraction or aberration of a natural eye. In addition to or instead of scanning the illuminating beam over each element of the array, all or multiple elements of the array can be illuminated simultaneously and the multiple interrogating rays thus generated can be gated by the use of an LCD aperture plate. Alternatively, an LCD aperture plate can be interposed between a wide illuminating beam and operated to selectively illuminate the beam deflector

摘要： An instrument and method for characterising eye-related optical systems, including the live human eye (18) involves scanning an illuminating light beam (22) from a light source and light detector unit (20) from element to element of a beam deflector array (12) of elements (14) arranged laterally across the optical axis (16) of eye (18). At each successive element (14) the illuminating beam (22) is deflected to form an interrogating beam (24) that is directed into the eye (18) at a peripheral angle that depends upon the lateral location of the deflector element. A return beam (23) is reflected or back-scattered from the cornea (38) and returned via the same deflector element to the light source and detector unit (20). This allows the interrogating beams to be scanned sufficiently rapidly into the eye to greatly reduce the variation of eye fixation and gaze that accompany other methods of measuring peripheral refraction or aberration of a natural eye. In addition to or instead of scanning the illumination beam (22) over each element (14) of the array (12), all or multiple elements (14) of the array (12) can be illuminated simultaneously and the multiple interrogating rays (24) thus generated can be gated by the use of an LCD aperture plate (26). Alternatively, an LCD aperture plate (28) can be interposed between a wide illuminating beam (22) and operated to selectively illuminate the beam deflector.

摘要： 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.

摘要： 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.

摘要： 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.
