The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm). ## Claims ### Claim 1 An ophthalmic device comprising: an implantable mask configured to increase the depth of focus of a human patient when the mask is implanted in an eye of the human patient, the mask comprising at least one dye capable of absorbing electromagnetic radiation of a predetermined range and allowing transmission of at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm, the mask comprising an aperture configured to transmit along an optical axis substantially all visible incident light; and a support structure configured to securely position the implantable mask in an optical path of the eye. ### Claim 2 (depends on 1) The ophthalmic device of claim 1, wherein the mask is configured to be substantially opaque to visible light. ### Claim 3 (depends on 1) The ophthalmic device of claim 1, wherein the mask is configured to have different degrees of opacity. ### Claim 4 (depends on 1) The ophthalmic device of claim 1, wherein the at least one dye comprises a first dye that absorbs a first range of electromagnetic radiation wavelengths, and a second dye that absorbs a second range of electromagnetic radiation wavelengths. ### Claim 5 (depends on 1) The ophthalmic device of claim 1, wherein the at least one dye comprises a moiety configured to eliminate a substantial amount of leaching of the at least one dye. ### Claim 6 (depends on 1) The ophthalmic device of claim 1, further comprising a lens body. ### Claim 7 (depends on 6) The ophthalmic device of claim 6, wherein the mask is attached to an anterior surface of the lens body. ### Claim 8 (depends on 6) The ophthalmic device of claim 6, wherein the mask is embedded within the lens body. ### Claim 9 (depends on 1) The ophthalmic device of claim 1, wherein the mask is configured to be implanted in the sulcus region of the eye. ### Claim 10 (depends on 1) The ophthalmic device of claim 1, wherein the support structure comprises a pair of haptics. ### Claim 11 (depends on 1) The ophthalmic device of claim 1, wherein the mask comprises a curvature. ### Claim 12 (depends on 1) The ophthalmic device of claim 1, wherein the mask is planar. ### Claim 13 (depends on 1) The ophthalmic device of claim 1, wherein the aperture is centered on the mask. ### Claim 14 (depends on 1) The ophthalmic device of claim 1, wherein the aperture is off-center on the mask. ### Claim 15 An ophthalmic device comprising: an implantable mask comprising an aperture configured to transmit along an optical axis substantially all visible incident light, the mask comprising a mask body configured to be substantially opaque to visible light and to be substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm to facilitate examining ocular tissue posterior to the mask; and a support structure configured to secure the mask in a sulcus region of the eye. ### Claim 16 (depends on 15) The ophthalmic device of claim 15, wherein the mask is configured to increase the depth of focus of an eye of a human patient when the mask is implanted in an eye of the human patient. ### Claim 17 (depends on 15) The ophthalmic device of claim 15, further comprising a lens body. ### Claim 18 (depends on 17) The ophthalmic device of claim 17, wherein the mask is attached to an anterior surface of the lens body. ### Claim 19 (depends on 17) The ophthalmic device of claim 17, wherein the mask is embedded within the lens body. ### Claim 20 (depends on 15) The ophthalmic device of claim 15, wherein the mask body comprises at least one dye capable of absorbing electromagnetic radiation.
