  • Ophthalmic surgery light transmitting apparatus
    Publication number: 20090187170
    Abstract: An ophthalmic surgery light transmitting apparatus has an optic fiber having a flexible length with a light source connector mounted on one end of the optic fiber and the opposite end of the optic fiber being adapted to be mounted to an ophthalmic surgery instrument to provide illumination for the instrument. The cross-sectional area of the optic fiber transitions as it extends from the end connected to the light source connector to the opposite end of the optic fiber. The optic fiber transitions from a larger cross-sectional area of the optic fiber at the light source connector to a smaller cross-sectional area of the optic fiber at the opposite end.
