An ophthalmic lens may comprise a posterior optic surface, an anterior optic surface, and an optic edge between the posterior optic surface and the anterior optic surface, wherein the optic edge forms a substantially circular perimeter having a thickness that varies periodically. The thickness of the optic edge may vary periodically for at least two cycles. Additionally, or alternatively, the ophthalmic lens may comprise an optic skirt coupled to the optic edge. The optic skirt can be configured to inhibit transmission of light around the optic edge.

An exemplary ophthalmic lens includes an optic comprising an anterior optic surface and a posterior optic, and a multi-curvature optical edge surrounding the optic and connecting the anterior optic surface to the posterior optic surface, the multi-curvature optical edge comprising a plurality of tangentially-connected curved surfaces configured to mitigate positive dysphotopsia by directing or diffusing from light incident on the multi-curvature optical edge away from a fovea of a patient.

An intraocular lens is provided that includes a refractive element and a mask. The refractive element has a first power in a first meridian and a second power greater than the first power in a second meridian. A magnitude of the first and second powers and a location of the first and second meridians are configured to correct astigmatism in a human eye. The mask is configured to block a substantial portion of light from passing through an annular region thereof and to permit a substantial portion of light to pass through a central aperture thereof to enhance an astigmatism correction rotational misplacement range and depth of focus.

A modular intraocular lens (IOL) with a ring configured to prevent glare artifacts. The ring includes a flange on the posterior rim, in which an anterior surface on the flange has a first profile and a posterior surface of the flange has a second profile non-parallel with the first profile. Non-parallel surfaces of the flange can be configured to defocus light transmitted at off-axis angles through an optic and the flange.

Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

An intraocular lens system comprising at least one intraocular lens having an anterior surface and a posterior surface, wherein at least one surface of the lens is aspherical to provide for a continuum of retinal images to be focused at the retina in an area between two retinal eccentricities. The system may include an anterior light-converging intraocular lens 16 for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens 17 for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein one or both surfaces of the anterior lens and/or one or both surfaces of the posterior lens are aspherical.

Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical polymeric materials or optical tissues is performed to address various types of vision correction.

An intraocular lens comprising: an optic zone; and a control zone positioned peripherally relative to the optic zone and configured to reduce, minimize, and/or eliminate negative peripheral pseudophakic dysphotopsia (PPD).

An intraocular lens is provided that includes a refractive element and a mask. The refractive element has a first power in a first meridian and a second power greater than the first power in a second meridian. A magnitude of the first and second powers and a location of the first and second meridians are configured to correct astigmatism in a human eye. The mask is configured to block a substantial portion of light from passing through an annular region thereof and to permit a substantial portion of light to pass through a central aperture thereof to enhance an astigmatism correction rotational misplacement range and depth of focus.
