This invention discloses methods and apparatus for providing an ophthalmic lens of variable optical power. The variable optic insert may have surfaces within that have differing radii of curvature. The variable optic insert may also comprise polarizing elements. In some examples, an intermediate optic piece may be formed to comprise a UV absorbing dye, allowing differential processing of regions on either side of the intermediate optic piece. In some embodiments, an ophthalmic lens is cast-molded from a silicone hydrogel. The various ophthalmic lens entities may include electroactive liquid crystal layers to electrically control refractive characteristics.

An accommodative intraocular lens includes an optic body having an optical power changing structure. There are two supporting structures disposed opposite one another about the optic body, each supporting structure configured to be connected at a distal end to a ciliary body after implantation in an eye of a patient and connected at a proximal end to the optic body. The two supporting structures are a zeroing supporting structure and an actuating supporting structure. The zeroing supporting structure is configured to not change the optical power of the optic body in an installation mode and an operation mode of the accommodative intraocular lens. An actuating supporting structure is configured to not change the optical power of the optic body in the installation mode but is configured to change the optical power of the optic body in the operation mode of the accommodative intraocular lens.

Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL) that has a non-zero residual spherical error that requires an estimated diffractive power addition in the IOL. In some embodiments, a plurality of laser pulses are applied to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, the estimated diffractive power addition to correct for the residual spherical error.

Ophthalmic devices and ophthalmic systems including alignment sidewalls and blend zones disposed therethrough are described. An example ophthalmic device may include a first and a second optical element having alignment sidewalls shaped to cooperatively couple. The alignment sidewall may include blend zones disposed in the sidewall shaped to transition the sidewall from a ridge to a surface of an optic zone of the optical element. The alignment sidewalls may define a cavity disposed between two coupled optical elements when the alignment sidewalls are cooperatively coupled into which a liquid crystal may be disposed. A method of assembling an ophthalmic device is described. An example method may include aligning a blend zone of a first optical element with a mating blend zone of a second optical element. The example method may further include cooperatively coupling alignment sidewalls of the first optical element and the second optical element.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for reducing dysphotopsia effects, such as haloes and glare. Exemplary ophthalmic lenses may include a central zone with a first set of two echelettes arranged around the optical axis, the first set having a profile in r-squared space. A middle zone includes a second set of two echelettes arranged around the optical axis, the second set having a profile in r-squared space that is different than the profile of the first set. A peripheral zone includes a third set of two echelettes arranged around the optical axis, the third set having a profile in r-squared space that is different than the profile of the first set and the profile of the second set, the third set being repeated in series on the peripheral zone.

An ophthalmic assembly for implantation in an anterior chamber of an eye of a patient to provide accommodation of the vision to said patient comprises a variable-focus lens and an actuator for modifying the focal length of the variable-focus lens. The ophthalmic assembly comprises an autofocus system configured to determine a distance parameter of an object that the patient's eye is looking at; a signal processing unit arranged to convert said distance parameter into a focal length value of the variable-focus lens; and an actuator control unit configured to control the actuator as a function of the focal length value received from said signal processing unit. A method for accommodating the vision of a patient using an opthamalic assembly is also disclosed.

Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method includes determining at least one photic phenomenon experienced by the subject after implantation of the IOL; and applying a plurality of laser pulses to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, a phase shift in the IOL to compensate for the photic phenomenon.

Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL). In some embodiments, a method includes applying a plurality of laser pulses to the IOL. The laser pulses can be configured to produce, by refractive index writing on the IOL, a predetermined change in phase profile of the IOL to increase spectacle independence.

A lens including a flexible refractive optic having a fixed refractive index, an electro-active element embedded within the flexible refractive optic, wherein the electro-active element has an alterable refractive index, and a controller electrically connected to the electro-active element wherein when power is applied thereto the refractive index of the electro-active element is altered.
