Masked intraocular implants and lenses
Abstract
Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.
Claims
exact text as granted — not AI-modified1 - 23 . (canceled)
24 . An ophthalmic device comprising:
an annular mask body with a central aperture that is configured to increase depth of focus of a patient, the body having an anterior surface and a posterior surface and comprising a substantially opaque material; a first linking member extending from an outer periphery of the body, the first linking member looping from a first location on the outer periphery of the body to a second location on the outer periphery of the body, the second location being circumferentially spaced apart from the first location; a second linking member extending from the outer periphery of the body, the second linking member circumferentially displaced from the first linking member, the second linking member looping from a third location on the outer periphery of the body to a fourth location on the outer periphery of the body, the fourth location being circumferentially spaced apart from the third location; and a third linking member extending from the outer periphery of the body, the third linking member circumferentially displaced from the second linking member, the third linking member looping from a fifth location on the outer periphery of the opaque portion to a sixth location on the outer periphery of the opaque portion, the sixth location being circumferentially spaced apart from the fifth location.
25 . The ophthalmic device of claim 24 , wherein the body comprises acrylic.
26 . The ophthalmic device of claim 24 , wherein the aperture has a diameter of less than about 2 mm.
27 . The ophthalmic device of claim 24 , wherein the first linking member, the second linking member, and the third linking member are connected to form a unitary structure.
28 . The ophthalmic device of claim 24 , wherein the first linking member, the second linking member, and the third linking member collectively surround the entire outer periphery of the body.
29 . The ophthalmic device of claim 24 , further comprising a lens body positioned posterior to the mask body.
30 . The ophthalmic device of claim 24 , further comprising a lens body formed around the mask body.
31 . The ophthalmic device of claim 30 , further comprising at least one haptic, at least one of the first linking member, the second linking member, or the third linking member being positioned adjacent to the at least one haptic.
32 . The ophthalmic device of claim 24 , wherein the posterior surface of the mask body is concave.
33 . The ophthalmic device of claim 24 , wherein the body and the linking members are substantially planar.
34 . The ophthalmic device of claim 24 , wherein the body and the linking members comprise the same material.
35 . The ophthalmic device of claim 24 , wherein the body and the linking members form a monolithic structure.
36 . The ophthalmic device of claim 24 , wherein the central aperture comprises optical power.
37 . An ophthalmic device comprising:
an annular mask body with a central aperture that is configured to increase depth of focus of a patient, the body having an anterior surface and a posterior surface and comprising a substantially opaque material; an outer hole region surrounding the mask, the outer hole region comprising at least one opening positioned around the mask; and an outer portion forming an outer periphery of the mask, the outer portion comprising a single integrated structure that connects to the mask body and surrounds the at least one opening.
38 . The ophthalmic device of claim 37 , wherein the central aperture comprises optical power.
39 . The ophthalmic device of claim 37 , wherein the annular mask is configured to transmit no more than about 2% of incident visible light.
40 . The ophthalmic device of claim 37 , wherein the central aperture comprises refractive properties.
41 . The ophthalmic device of claim 37 , wherein the aperture has a diameter of less than about 2 mm.
42 . The ophthalmic device of claim 37 , further comprising at least one haptic, the outer portion being adjacent to the at least one haptic.
43 . The ophthalmic device of claim 37 , wherein the posterior surface of the mask body is concave.
44 . The ophthalmic device of claim 37 , wherein the outer portion is curved.
45 . The ophthalmic device of claim 37 , wherein the at least one opening comprises three circumferentially spaced apart openings.Cited by (0)
