Hyperchromatic presybyopia-correcting intraocular lenses
An ophthalmic device includes at least one ophthalmic lens and at least one diffractive structure for the at least one ophthalmic lens. The ophthalmic lens(es) have at least one base focal length and a base power for a first wavelength of visible light. The diffractive structure(s) have a chromatic aberration such that the diffractive structure(s) have a first power for the first wavelength of visible light and a second power for a second wavelength of visible light. A difference between the first power and the second power is at least two diopters.
INTRAOCULAR LENSES HAVING ZONE-BY-ZONE STEP HEIGHT CONTROL
A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having anterior surface, a posterior surface and at least one diffractive structure including a plurality of zones. The at least one diffractive structure is for at least one of the anterior surface and the posterior surface. Each zone includes at least one echelette having a least one step height. The step height(s) are individually optimized for each zone. To compensate chromatic aberration of eye from distance to a range of vision, a greater than 2 phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by . Hence chromatic aberration of eye may be compensated to improve vision from distance to near.

The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) and associated method for their design and use. The apparatus includes one or more optical zones, including an optical zone defined by a polynomial-based surface coincident at a plurality of meridians having distinct cylinder powers, wherein light incident to a given region of each of the plurality of meridians, and respective regions nearby, is directed to a given point of focus such that the regions nearby to the given region direct light to the given point of focus when the given meridian is rotationally offset from the given region, thereby establishing an extended band of operation, and wherein each of the plurality of meridians is uniformly arranged on the optical zone for a same given added power (in diopters) up to 1.0D (diopters).
Ophthalmic lens having morphed sinusoidal phase shift structures
An ophthalmic lens includes an optic comprising an anterior surface, a posterior surface, and an optical axis. At least one of the anterior surface and the posterior surface has a surface profile including a base curvature and a plurality of morphed sinusoidal phase shift structures. The base curvature may correspond to a base optical power of the ophthalmic lens, and the morphed sinusoidal phase shift structures may be configured to extend depth of focus of the ophthalmic lens at intermediate or near viewing distances.
Intraocular lens having hinged haptic structures
An ophthalmic device includes an optic including an optic axis and a haptic structure coupled with the optic. The haptic structure includes an inner ring comprising a plurality of hinges such that portions of the inner ring reside at different radii from the optic axis.

The second loop is oriented opposite the first loop.
Intraocular lenses having zone-by-zone step height control
A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having anterior surface, a posterior surface and at least one diffractive structure including a plurality of zones. The at least one diffractive structure is for at least one of the anterior surface and the posterior surface. Each zone includes at least one echelette having a least one step height. The step height(s) are individually optimized for each zone. To compensate chromatic aberration of eye from distance to a range of vision, a greater than 2 phase step height may be employed and the step height(s) folded by a phase, which is an integer multiple of two multiplied by . Hence chromatic aberration of eye may be compensated to improve vision from distance to near.
