Abstract: Methods and apparatus to improve or restore vision by causing a rebooting of the visual system of an eye with modification of visual search, sampling and stimulation away from the preferred retinal locus of fixation of an eye to enhance neural integration and perception of visual information from within the field of view are described herein. Some embodiments cause transient, reversible or repeatable redirection of environmental light away from the preferred retinal locus of fixation of an eye to multiple retinal locations that are not the preferred retinal locus of fixation. Some embodiments reduce exposure of environmental light at the preferred retinal locus of fixation of an eye for a determinable interval at a determinable rate. Some embodiments cause a defocusing of environmental light at the preferred retinal locus of fixation in an eye with a visual impairment or loss.

Abstract: The present disclosure provides a three-lens IOL system including a first, anterior lens, a second, posterior lens rigidly connected to the first lens by at least one rigid member such that the second lens is a fixed distance from the first lens along an axis, a third, center, moveable lens positioned between the first lens and the second lens and adapted to move linearly along the axis anteriorly in a direction of the first lens or posteriorly in a direction of the second lens to change an optical power of the system, and an articulating actuator that contacts the moveable lens and a capsular bag of an eye when the IOL system is implanted in the capsular bag, the articulating actuator adapted to move the moveable lens linearly along the axis.

Abstract: An augmented reality display system includes a first beam path for a foveal inset image on a holographic optical element, a second beam path for a peripheral display image on the holographic optical element, and pupil position tracking logic that generates control signals to set a position of the foveal inset as perceived through the holographic optical element, to determine the peripheral display image, and to control a moveable stage.

Abstract: A fluidic telescope includes a first lens configured to be arranged in the eye of a patient, and a second lens having a chamber with fluid disposed therein, the second lens being a variable focus fluidic lens capable of varying the shape thereof so as to selectively form an additive plus lens, an additive minus lens, and a Galilean telescope when positioned so as to be along the same optical axis as the first lens, wherein the second lens is configured to be capable of moving the focal point thereof forward or backward by increasing or decreasing the fluid in the chamber.

Abstract: An intraocular implant adapted to be implanted within the interior of a human eye is disclosed. The aforesaid implant is selected from a group consisting of: an intracorneal implant, an anterior chamber implant, a sulcus implant, implant in the bag, posterior chamber implant and any combination thereof. The implant comprises means selected from a group consisting of reflective surfaces and electronic device. The implant is adapted to form at least one image of at least part of the field of vision on the retina. The image is selected of a group consisting of: artificial image and reflected image, and any combination thereof. The image is formed on the retina by a predetermined indirect path selected from (z) optical reflective path and (U) electronic processing. Optionally, also a refracted image may also be created on the retina.

Abstract: A lens system is provided. The lens system includes a lens adapted to be positioned along the main optical axis of the eye and a control unit. The control unit is operable with the lens to alter the focal length of the lens based at least partly upon a condition, such that the lens alters light rays and focuses the rays on the retina of the eye.

Abstract: The present invention relates to polymeric compositions useful in the manufacture of biocompatible medical devices. More particularly, the present invention relates to certain carboxylic monomers capable of polymerization to form polymeric compositions having desirable physical characteristics useful in the manufacture of ophthalmic devices. The polymeric compositions comprise polymerized carboxylic hydrophilic siloxanyl monomers.

Abstract: An artificial vision system including a sealed capsule adapted for intraocular placement upstream of a retina, an electronic display located within the sealed capsule and focusing optics located within the sealed capsule and arranged for focusing an image on the electronic display onto the retina.

Abstract: An intraocular lens system for implantation in the eye to modify the lens system of the eye comprising the cornea and the natural or existing artificial lens in the eye, and a method for using the same. The system and method comprises a lens having a high minus portion, adapted to be implanted in the eye to create a lens system that functions as a teledioptic lens system which, when used without an external lens, provides unmagnified and peripherally unrestricted vision and which, when used with an external lens, provides magnified and peripherally restricted vision to correct for macular degeneration. The lens can be attached to the iris, to a portion of the iris that was removed by iridectomy, or can be implanted in the cornea. The lens can also include a plus portion that is surrounded by the high minus portion.

Abstract: An intraocular lens implant particularly suitable for use by patients suffering from tunnel vision, the implant includes a sealed implant housing associated with mounting haptics and defining a forward end and a rearward end, at least one negative lens arranged adjacent the forward end and at least one positive lens arranged rearwardly of the at least one negative lens.

Abstract: An intracorneal astigmatic, rectangular onlay has been discovered that can correct for astigmatism by physically adjusting the shape of the cornea. This astigmatic onlay can be narrow or wide and can easily be placed in the stroma of the cornea. The onlay can be placed on top of a laser ablation or on a spherical lens, which in turn was implanted either under a tissue flap or in a stromal pocket. The astigmatic onlay is easy to position at precisely the correct angle to compensate for the astigmatism-causing meridional distortion. This invention greatly increases the utility and practicality of intracorneal spherical lenses and makes it easy to position the astigmatic correcting ridge at precisely the correct angle to compensate for the astigmatism. The invention greatly decreases the inventory needed to compensate for both spherical and astigmatic corrections. For example, spherical corrections from +5 D to −5 D at 0.
