Abstract
The present invention provides an ophthalmic lens capable of correcting or minimizing presbyopia, or of functioning used as an anti-myopic lens. The ophthalmic lens can be a contact lens, a phakic intraocular lens or an aphakic intraocular lens. The ophthalmic lens comprises an optical zone, the optical zone having a first surface and an opposite second surface and including a coma-like wavefront aberration oriented vertically from the top to the bottom of the ophthalmic lens. In addition, the present invention provides a method for minimizing/correcting presbyopia or for preventing children's eyes from becoming severely myopic.
Claims56
An ophthalmic lens comprising an optical zone, wherein the optical zone has a first surface and an opposite second surface and includes a coma-like wavefront aberration oriented vertically from the top to the bottom of the lens, wherein the coma-like wavefront aberration is, or is an equivalent of, a wavefront aberration described by any one of third order, fifth order, seventh order Zernike coma-like terms, and combinations thereof in proposed OSA Standard (Optical Society of America) Zernike Polynomials.
A customized ophthalmic lens, comprising an optical zone which, alone or in combination with the optics of an eye, produce a vertically oriented coma-like wavefront aberration, wherein the coma-like wavefront aberration is, or is an equivalent of, a wavefront aberration described by any one of third order, fifth order, seventh order Zernike coma-like terms, and combinations thereof in proposed OSA Standard (Optical Society of America) Zernike Polynomials.
A method for making an ophthalmic lens, comprising the step of producing the ophthalmic lens by a manufacturing means, wherein the ophthalmic lens comprises an optical zone, the optical zone having a first surface and an opposite second surface and including a coma-like wavefront aberration oriented vertically from the top to the bottom of the lens, wherein the coma-like wavefront aberration is, or is an equivalent of, a wavefront aberration described by any one of third order, fifth order, seventh order Zernike coma-like terms, and combinations thereof in proposed OSA Standard (Optical Society of America) Zernike Polynomials.
A method for minimizing or correcting presbyopia, comprising the step of reshaping a cornea of an eye to produce a vertically oriented coma-like wavefront aberration.
