Intraocular implant with removable optic
Intraocular implants and methods of forming intraocular implants are described herein. The intraocular implant can include a powered optic and a lens holder. The optic can be mechanically coupled to an inner periphery of the lens holder to form the intraocular implant. A portion of the lens holder can include a mask disposed about the optic to increase depth of focus in a human patient.
1. An intraocular lens (IOL) comprising:
a lens holder comprising an outer periphery and an inner periphery, the inner periphery defining an aperture, the aperture extending from an anterior surface of the lens holder to a posterior surface of the lens holder, an annular portion of the lens holder being substantially opaque to visible light, the substantially opaque annular portion being disposed about the aperture and embedded within the lens holder; and
an optic positioned in the aperture and mechanically coupled with the inner periphery of the lens holder;
wherein the aperture comprises a diameter of between about 0.85 mm to about 2.2 mm;
wherein the aperture is sized and configured to increase depth of focus in a human patient when the intraocular lens is implanted in an eye of the human patient;
wherein the optic includes an anterior region, a central region, and a posterior region, a diameter of the anterior region and a diameter of the posterior region are greater than a diameter of the central region of the optic;
wherein the aperture includes an anterior region, a central region, and a posterior region, a diameter of the anterior region of the aperture and a diameter of the posterior region of the aperture are greater than a diameter of the central region of the aperture;
wherein the central region of the optic is sized and configured to interface and mechanically interlock with the central region of the aperture.
2. The intraocular lens of claim 1 , wherein the lens holder is powered.
3. The intraocular lens of claim 1 , wherein the entire lens holder is substantially opaque to visible light.
4. The intraocular lens of claim 1 , wherein the substantially opaque portion of the lens holder is substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between 750 nm and about 1500 nm to facilitate examining ocular tissue posterior to the intraocular implant.
5. The intraocular lens of claim 1 , wherein the optic comprises acrylic.
6. The intraocular lens of claim 1 , wherein the lens holder comprises acrylic.
7. The intraocular lens of claim 1 , wherein the lens holder comprises a first material and the optic comprises a second material, the second material being different from the first material.
8. The intraocular lens of claim 1 , wherein the lens holder comprises haptics.
9. The intraocular lens of claim 1 , wherein the lens holder is integrally formed as one piece.
