Abstract:
The present disclosure is directed to lenses, devices, methods and/or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and/or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassing far to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and/or methods include embodiments that address foveal and/or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and/or refractive surgery.
Abstract:
Contact lenses and methods for designing and manufacturing contact lenses are disclosed. The contact lenses comprise a zone outside a central optic zone having a thickness profile with a varying thickness. The thickness profile provides rotational force to rotationally orient the contact lens when applied to a recipient eye. The thickness profile includes substantially curvilinear lines of constant thickness that extend generally horizontally across the lens. The curvilinear lines of substantially constant thickness may match the contact lines of the margins of at least one of the eyelids of the recipient.
Abstract:
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.

Abstract:
An ophthalmic lens element includes an upper distance viewing zone and a lower near viewing zone. The upper distance viewing zone includes a central region with a first refractive power for clear distance vision and peripheral regions that are relatively positive in power compared to the first refractive power. The lower near viewing zone has a central region that is relatively positive in power compared to the first refractive power to account for accommodative lag. The powers of the peripheral regions of the lower near viewing zone are one of: i) equal to the power of the central region of the lower near viewing zone, ii) relatively positive in comparison to the power of the central region of the lower near viewing zone.
Abstract:
The invention provides a use of panthenol or dexpanthenol in the prevention and/or treatment of contact lens papillary conjunctivitis in a subject. A contact lens care solution containing 0.001 to 10% by dry weight dexpanthenol is also provided.
