20210361415 · 2021-11-25 ·

The present disclosure concerns a curvature-changing, accommodative intraocular lens (IOL) for implantation in the capsular bag of a patient's eye. The IOL includes a fluid optic body having a cavity for containing an optical fluid, the cavity at least partially defined by a sidewall extending around the cavity and defining a diameter of the cavity and a deformable optical membrane intersecting the sidewall around a circumference of the sidewall and spanning the diameter of the cavity. The IOL further includes a second optic body spaced a distance apart from the fluid optic body and a plurality of struts extending from the sidewall and coupling the fluid optic body to the second optic body. The struts are configured such that axial compression of the capsular bag causes the struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane.

LIGHT CONTROL DEVICES AND METHODS FOR REGIONAL VARIATION OF VISUAL INFORMATION AND SAMPLING
20210364807 · 2021-11-25 ·

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.

Accommodating intraocular lenses and methods of use

Accommodating intraocular lenses and methods of use. The accommodating intraocular lenses include peripheral regions that are adapted to be more responsive to certain types of forces than to other types of forces. For example, the accommodating intraocular lenses can include haptics that are stiffer in an anterior-to-posterior direction than in a radial direction.

Various embodiments are described herein for an ocular device implantable in a user's eye and which has an adjustable optical element for varying one or more optical properties for the eye such as, but not limited to, providing a dynamically adjustable aperture stop to control the amount of incoming light, filtering incoming light, polarizing incoming light, and/or varying a depth of field for the eye.

Intraocular lenses that improve peripheral vision

Lenses and methods are provided for improving peripheral and/or central vision for patients who suffer from certain retinal conditions that reduce central vision or patients who have undergone cataract surgery. The lens is configured to improve vision by having an optic configured to focus light incident along a direction parallel to an optical axis at the fovea in order to produce a functional foveal image. The optic is configured to focus light incident on the patient's eye at an oblique angle with respect to the optical axis at a peripheral retinal location disposed at a distance from the fovea, the peripheral retinal location having an eccentricity between −30 degrees and 30 degrees. The image quality at the peripheral retinal location is improved by reducing at least one optical aberration at the peripheral retinal location. The method for improving vision utilizes ocular measurements to iteratively adjust the shape factor of the lens to reduce peripheral refractive errors.
