In some examples, a speculum includes a first arm having one or more blades located at an end of the first arm and a second arm having one or more blades located at an end of the second arm, a set of light-emitting elements on the one or more blades, and a signal carrier running along at least a portion of the first and second arms and having one end configured to connect to a signal source to receive light and/or electricity and one or more opposite ends respectively coupled with the set of light-emitting elements, the signal carrier being configured to transmit the light and/or electricity from the signal source to the set of light-emitting elements. ## Claims ### Claim 1 A speculum comprising: a first speculum arm comprising a first speculum arm blade located at a distal end of the first speculum arm, wherein the first speculum arm blade comprises a first curved structure that is configured to engage with a first eyelid and spread apart the first eyelid; a second speculum arm comprising a second speculum arm blade located at a distal end of the second speculum arm, wherein the second speculum arm blade comprises a second curved structure that is configured to engage with a second eyelid and spread apart the second eyelid, wherein a first open portion of the first curved structure and a second open portion of the secure curved structure face in opposite directions from each other; a first set of light-emitting elements located on a first surface of the first curved structure, the first surface of the first curved structure touching an eyeball when the speculum is positioned for surgery, the first set of light-emitting elements being configured to provide illumination to one or more areas of an eye structure; a second set of light-emitting elements located on a second surface the second curved structure, the second surface of the second curved structure touching the eyeball when the speculum is positioned for surgery, the second set of light-emitting elements being configured to provide illumination to one or more areas of the eye structure; and a signal carrier running along at least a portion of the first speculum arm and the second speculum arm, the signal carrier having one end configured to connect to a signal source and receive at least one of light and electricity from the signal source, and one or more opposite ends respectively coupled with the first set of light-emitting elements and the second set of light-emitting elements, the signal carrier being configured to transmit the at least one of the light and electricity from the signal source to the first set of light-emitting elements and the second set of light-emitting elements. ### Claim 2 (depends on 1) The speculum of claim 1, wherein a relative position or distance of the first speculum arm and the second speculum arm is adjustable, and wherein the first curved structure and the second curved structure are configured to slip underneath and above respective eyelids of the eye structure to open, hold, or limit movement of the respective eyelids. ### Claim 3 (depends on 2) The speculum of claim 2, wherein an inferior surface of each of the first curved structure and the second curved structure is configured to make contact with or attach to a sclera or conjunctiva of an eyeball associated with the eye structure in order to open, hold, or limit movement of the respective eyelids. ### Claim 4 (depends on 2) The speculum of claim 2, wherein the first set of light-emitting elements and the second set of light-emitting elements are configured to provide illumination to one or more areas of the eye structure while the first curved structure and the second curved structure open, hold, or limit movement of the respective eyelids. ### Claim 5 (depends on 1) The speculum of claim 1, wherein the signal carrier comprises an electrical cable, wherein the signal source comprises a power source, and wherein the first set of light-emitting elements and the second set of light-emitting elements comprise light-emitting diodes (LEDs). ### Claim 6 (depends on 1) The speculum of claim 1, wherein the signal carrier comprises a fiber optic cable, wherein the signal source comprises a light source, and wherein the first set of light-emitting elements and the second set of light-emitting elements comprise respective portions of the fiber optic cable. ### Claim 7 (depends on 6) The speculum of claim 6, wherein the respective portions of the fiber optic cable comprise at least one of fiber strands, fiber filaments, fibers, and fiber cable ends. ### Claim 8 (depends on 1) The speculum of claim 1, wherein the first curved structure and the second curved structure comprise apertures enclosing or containing the first set of light-emitting elements and the second set of light-emitting elements. ### Claim 9 (depends on 1) The speculum of claim 1, wherein the first curved structure comprise a first bottom blade and a first top blade, wherein the second curved structure comprise a second bottom blade and a second top blade, wherein the first set of light-emitting elements are located on the first bottom blade and the second set of light-emitting elements are located on the second bottom blade. ### Claim 10 (depends on 1) The speculum of claim 1, further comprising: one or more adjustable anterior segment lights positioned at one or more respective locations on the speculum, the one or more adjustable anterior segment lights being coupled with the signal carrier, the signal carrier providing at least one of light and electricity used by the one or more adjustable anterior segment lights to provide additional illumination to the eye structure.
