Abstract

Embodiments concern an intraocular implantable device operable comprising a disk-shaped body having a symmetry axis and which further comprises a light-transmissive portion and an opaque portion wherein the light-transmissive portion is decentered with respect to the symmetry axis.

First claim

What is claimed is:

1. An implantable intraocular lens (IOL) comprising:
a substantially circular-shaped intraocular lens body implantable behind a cornea of an eye of a patient and having a rotational symmetry axis that virtually intersects a location on a retina lying within a radius of a non-dilated pupil,
the substantially circular-shaped intraocular lens body having an anterior surface and a posterior surface, comprising:
an opaque portion that is non-transmissive to visible light; and
a light-transmissive portion consisting of a single pinhole that is decentered in its entirety with respect to the rotational symmetry axis of the substantially circular-shaped intraocular lens body such that, when the circular-shaped intraocular lens body is operably engaged with a patient's eye, the optical axis of the pupil is entirely outside the pinhole, said pinhole is operable to direct light from the anterior surface to the posterior surface along an optical axis that is different from the symmetry axis of the substantially circular-shaped intraocular lens body,

wherein the optical axis of the single pinhole intersects a second location of the retina exceeding the radius of the non-dilated pupil,
wherein substantially the entirety of the intraocular lens body is comprised by the opaque portion,
wherein when the substantially circular-shaped intraocular lens body operably engages with a patient's eye, the rotational symmetry axis coincides with the optical axis of the eye, and
further wherein the intraocular lens body is configured to direct light propagating through the light-transmissive portion such to be incident onto the second location that is within the eye's macula but not on the fovea located in the macula.

2. The intraocular lens of claim 1 , wherein the substantially circular-shaped intraocular lens body is disk-shaped or lens-shaped.

3. The intraocular lens of claim 1 , wherein the light-transmissive portion is a physical through-hole that extends from the anterior surface to the posterior surface of the substantially circular-shaped intraocular lens body.

4. The lens of claim 1 , wherein the substantially circular-shaped body is operable to at least partially or fully compensate for optical errors of the patient's eye.

5. The intraocular lens of claim 4 , wherein the substantially circular-shaped body is operable to at least partially compensate for myopia, hyperopia and/or astigmatism of the patient's eye.

6. The intraocular lens of claim 1 , wherein said light-transmissive portion comprises a distal end and a proximal end, further wherein said distal end and said proximal end are shaped in a biconcave or biconvex manner.
