Intra-ocular implant

摘要

An intra ocular implant consisting of optical elements, adapted to forming images on the retina, especially useful in treating presbyopic patients, patients with AMD, patients with other diseases of the retina, and patients in which future development of retinal disorders may occur. An intra ocular implant wherein at least one mirror is operationally connected to the action of the ciliary muscle or its effect on the zonules and capsule of the natural lens; and wherein the mirror is adapted to change curvature, position or optical properties, such that bringing a plurality of objects at different distances into focus is facilitated in presbyopic patients. A lens assembly comprising an intra ocular lens and, an adjustable external or contact lens comprising at least in part of light polarizing material; the assembly at least partially polarizes at least part of the central visual field, at least part of the peripheral visual field or both in any angle.

主权项

1. An intra ocular implant for magnifying an incoming image comprising:
an optical axis; a body member having optical properties; and, an optical arrangement having a second axis perpendicular to said optical axis, said optical arrangement adapted to form, on a retina of a patient with a diseased central retina, at least one magnified image relative to the incoming image, wherein the magnified image comprises at least part of a peripheral visual field and at least part of a central visual field, said optical arrangement comprising said body member and only at least two mirrors, said at least two mirrors not extending to a radially outermost edge of said body member along said second axis; wherein said mirrors are adapted to reflect natural visible, ambient light onto the retina in a light path comprising said at least part of the peripheral visual field and said at least part of the central visual field, said mirrors comprising a reflective coating wherein the reflective coating is a dielectric coating having multiple thin layers applied in a vaporized form; and at least part of said implant is further coated with at least one protective biocompatible coating layer.
