摘要

An ophthalmic illuminator (10) is disclosed, one embodiment comprising: an illumination source (14), wherein the illumination source produces an arc (55); a lens (23) for focusing light (28) produced by the illumination source arc; and an optical fiber (34) for carrying the focused light to a surgical site in an eye; wherein the illumination source is positioned offset from a longitudinal axis of the optical fiber to compensate for shifting of the illumination source arc over time. The offset position can be such that the illumination source is positioned in a vertically offset position from the longitudinal axis of the optical fiber (34). The longitudinal axis corresponds to the optical path axis of the optical fiber. The ophthalmic illuminator can further comprise a reflector (70) for reflecting the light produced the illumination source (14) arc (55), wherein the reflector is positioned offset from the illumination source to decrease the rate of erosion of an illumination source cathode (65).
