Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing symmetric or asymmetric optic with aspheric surface which redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The intraocular lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the intraocular lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the intraocular lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles.

Intraocular lens that improves overall vision where there is a local loss of retinal function

A method of quantifying the effect of peripheral optical errors on patient locomotion includes projecting a pattern on the floor that includes a discrete shapes and empty spaces between the discrete shapes. The method also includes tracking a position of the participant along the pattern as the participant traverses the pattern, and determining foot placement accuracy, utilizing a optical motion capture system and a computer, as the participant walked through the pattern by determining a total area of overlap between the participant's feet and the empty spaces of the pattern. In another embodiment, the method includes arranging obstacles in front of a participant, intermittently displaying a character in front of the participant, determining participant's accuracy in identifying or counting the characters, and determining the participant's step length and foot clearance as the participant steps over the obstacles to quantify the effect of the peripheral optical errors on the participant's locomotion.

System and method for determining the impact of peripheral optical errors on patient locomotion

Intraocular lenses with a base optical power and a customized add power. The add power is customized based on at least one of ocular biometry of an individual, position of the intraocular lens in the eye and a preferred reading distance.

Intraocular lenses with customized add power

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 &#x2212;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.

Intraocular lenses that improve peripheral vision

A multi-piece IOL assembly is provided that includes a platform and an optic. The platform has an inner periphery surrounding an inner zone of the platform. The optic has an optical zone, an outer periphery and a retention mechanism disposed on the outer periphery. The optic is configured to be disposed in the inner zone of the platform and to extend to a location between the inner periphery and the outer periphery of the platform to be secured to the platform at the location. The platform can be secured to an inner periphery of the eye or can be formed into a natural lens by cutting the lens using a laser or other energy source.

An implantable glaucoma shunt for treating glaucoma in an eye is disclosed herein. The glaucoma shunt may comprise a plurality of strips adapted to be positioned on a sclera of the eye and an elastomeric drainage tube having an outflow end connected to the plurality of strips and an opening thereof. The drainage tube may have an open lumen and a length sufficient to extend into the anterior chamber of the eye. The plurality of strips may be substantially parallel with one another or the plurality of strips may diverge from one another. In an embodiment, the disclosed glaucoma shunt may be manufactured by removing material from a prior-art type glaucoma shunt. The disclosed glaucoma shunt may be inserted via an insertion tool.

The present disclosure relates to devices, systems, and methods for improving or optimizing peripheral vision. In particular, methods are disclosed which include utilizing particular characteristics of the retina in improving or optimizing peripheral vision. Additionally, various IOL designs, as well as IOL implantation locations, are disclosed which improve or optimize peripheral vision.

Ophthalmic devices, system and methods that improve peripheral vision

Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing a piggyback lens which in combination with the cornea and an existing lens in the patient's eye redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The piggyback lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the piggyback lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the piggyback lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles.
