The present disclosure is directed to lens, methods of making, designing lens and/or methods using lens in which performance may be improved by providing one or more steps in the central portion of the optical zone and one or more steps in the peripheral portion of the optic zone. In some embodiments, such lens may be useful for correcting refractive error of an eye and/or for controlling eye growth.

Ophthalmic optical lens for vision correction having one or more areas of more positive power

An ophthalmic lens system for reducing the risk of progression of a myopic eye by selectively maintaining, inducing or creating asymmetry of the peripheral retinal profile for the eye. A method for reducing the risk of progression of myopia comprising determining the magnitude of asymmetry of the on-axis/off-axis refractive error profile or eye length profile of the eye and providing an ophthalmic lens system that corrects for and provides acceptable on-axis vision and simultaneously controls the position of the off-axis refractive error profile or eye length profile such that resultant profile of the eye is asymmetric.

Systems, methods and devices for controlling the progression of myopia

A method for assessing the similarity between a power profile of a manufactured optic device and a nominal power profile upon which the power profile of the manufactured optic device is based. The method comprises measuring the power profile of manufactured optic device, identifying a region of interest from the measured power profile of manufactured optic device, and applying an offset to the measured power profile to substantially minimize a statistical quantifier for quantifying the similarity between the nominal power profile and the offset measured power profile. The method further comprises comparing the offset and the statistical quantifier to predefined quality control metrics, determining whether the measured power profile meets the predefined quality control metrics based, at least in part on the comparison. In exemplary embodiments, the method may further comprise determining whether to associate the manufactured optic device with another nominal power profile, if the measured power profile does not meet the predefined quality control metrics.

Systems and methods for determining the quality of a reproduced (manufactured) optic device

Contact lenses are described with a corneal remodelling effect. This corneal remodelling effect is one or both of broad-area corneal remodelling and localized remodelling. The contact lenses may also have a refractive power. The refractive power may vary across the lens and for myopia may have increased power centrally. The increased power may be provided over a lens area that has increased thickness due to localized remodelling.

Corneal remodelling contact lenses and methods of treating refractive error using corneal remodelling

Contact lenses are described with a corneal remodelling effect. This corneal remodelling effect is one or both of broad-area corneal remodelling and localised remodelling. The contact lenses may also have a refractive power. The refractive power may vary across the lens and for myopia may have increased power centrally. The increased power may be provided over a lens area that has increased thickness due to localised remodelling.

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.
