    摘要： Apparatus to measure the size of an optic zone of a lens, particularly a contact lens or intraocular lenses, and the refractive power of that optic zone includes an illumination system with a light source and a first lens train producing a collimated beam of light from the light source, and a second lens train including an observation system coaxial with the illumination system and focusing the collimated beam so that the observation system allows an observer to observe a magnified image of the lens to be measured. The lens to be measured is disposed on a mounting plate positioned in the collimated light beam between the first and second lens trains. A planar knife edge is positioned within the focused light beam of the second lens train so that it occludes a part of that beam. A micrometer or similar device is attached to the mounting plate so as to measure the observed size of the optic zone or zones of the lens. The distance between the light source and the first lens train is variable to allow the refractive power of the optic zone or zones of the lens to be determined.

    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： A contact lens having near vision and distance vision portions, the lens being movable on the eye between first and second positions, those positions corresponding with aligning the wearer's vision through the near vision and distance vision portions respectively. The lens is positionally stable on the eye in each of the two positions, and requires a force to be applied to the lens to move between the first and second positions. Preferably the lens has a back surface and a front surface, and said back surface has either one or two major back curve zones occupying a major portion of the lens back surface.

    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： 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.
