Masked intraocular devices
First Claim
1. An ophthalmic device having an imaging area for enhancing depth of focus in an eye of a human patient, the ophthalmic device comprising:
- a mask configured to be implanted posterior of a cornea of an eye, the mask comprising a single, optical aperture configured to transmit along an optical axis substantially all incident visible light, the single, optical aperture sized to increase the depth of focus sufficiently to treat presbyopia in the human patient, and a portion configured to be substantially opaque to visible light and to surround at least a portion of the aperture, the substantially opaque portion configured to be at least partially disposed within the imaging area; and
a plurality of light transmission structures disposed within the substantially opaque portion and configured to allow some visible light to pass through the substantially opaque portion, the light transmission structures comprising a wall surrounding a recess that extends at least partially between an anterior surface and a posterior surface of the mask, substantially all of the light transmission structures being similarly shaped, and wherein the light transmission structures are positioned at irregular locations to reduce projection of diffraction patterns visible to the human patient due to the transmission of visible light through the light transmission structures,wherein anterior portions of substantially all of the light transmission structures are spaced apart by a minimum distance.

Abstract
An ophthalmic device that includes a mask configured to be implanted posterior of the cornea. The mask is configured to increase the depth of focus of the patient. The mask includes an aperture configured to transmit along an optical axis substantially all incident light and a substantially opaque portion surrounding at least a portion of the aperture. The ophthalmic device can further include a plurality of light transmission structures configured to allow some light to pass through the substantially opaque portion. The light transmission structures are configured to minimize generation of visible artifacts due to the transmission of light through the light transmission structures.

23. An ophthalmic device, comprising:
-
an intraocular device configured to be implanted posterior of a cornea; a mask coupled with the intraocular device, the mask having an inner periphery configured to increase the depth of focus of a human patient, the mask comprising a central aperture configured to transmit along an optical axis substantially all incident visible light and a portion configured to be substantially opaque to visible light and to surround at least a portion of the aperture, the portion configured to be substantially opaque being disposed within the optical zone of the ophthalmic device, the opaque portion comprising an inner band and an outer band disposed outward of the inner band, the inner band substantially surrounding the aperture; and a plurality of transmissive structures in the opaque portion, wherein each of the transmissive structures comprises a wall surrounding a recess that extends at least partially between an anterior surface and a posterior surface of the mask, wherein at least one of size, shape, orientation, and minimum spacing from a nearest neighboring transmissive structure of a substantial portion of the plurality of transmissive structures is different from at least one of size, shape, orientation, and minimum spacing from a nearest neighboring transmissive structure of another substantial portion of the plurality of transmissive structures, wherein the inner band is devoid of transmissive structures, and wherein each of the plurality of transmissive structures is smaller than the central aperture. - View Dependent Claims (24, 25, 26, 27, 28)

29. An ophthalmic device configured to increase the depth of focus of a human patient comprising:
-
a mask having an anterior surface extending between an outer periphery and a central optical axis of the mask; the mask having a posterior surface extending between the outer periphery and the central optical axis of the mask; a substantially opaque portion extending between the anterior and posterior surfaces and between the outer periphery and the central optical axis, the opaque portion comprising an inner region and an outer region disposed outward of the inner region, the opaque portion configured to substantially prevent transmission of light; an aperture disposed about the central optical axis and configured to transmit substantially all incident light, the aperture having a dimension generally transverse to the optical axis, the dimension being about 2.2 millimeters or less; a plurality of holes having a hole entrance at the anterior surface and extending from the anterior surface to the posterior surface, each of the plurality of holes being substantially smaller than the aperture; wherein the holes are positioned at irregular locations outward of the inner region to reduce the generation of visible artifacts due to the transmission of light through the holes; and wherein the inner region is devoid of open area. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
