Abstract: A myopia management soft contact lens design derive from analysis of overnight orthokeratology procedure that is to obtain the corneal height data before and after treatment according to reference position of cornea before and after treatment by mathematical calculation and then superimpose data with reference position of cornea, and then obtain corresponding central optical zone size and peripheral treatment zone size by obtaining the difference between corneal changes before and after treatment using corneal height data and tangential curvature data, and then calculate power change data before and after corneal treatment by using position of central optical zone and peripheral treatment zone to match the axial curvature data, the algorithm, and then use the power change data to distinguish different myopia power correction ranges to analyze the corresponding different power profile, and then apply this power profile to front curved surface of lens for the manufacture of soft contact lenses.

Abstract: The present disclosure relates to contact lenses for use with eyes experiencing eye-length related disorders, like myopia with or without astigmatism. This invention relates to a contact lens for managing myopia with or without astigmatism; wherein the contact lens is configured with an optical zone defined substantially centred about its optical axis to provide a meridionally and azimuthally variant power distribution resulting, at least in part, in a foveal correction of the myopic eye and, at least in part, resulting in a conoid of partial blur at the retina of the myopic eye, serving as a directional cue or an optical stop signal; and a non-optical peripheral carrier zone about the optical zone configured with a invariant azimuthal thickness distribution, with or without rotation assisting features, to further provide temporally and spatially varying stop signals to decelerate, control, inhibit, or reduce the rate of myopia progression substantially consistent over time.
