摘要：
A surgical probe system comprising a surgical probe having a probe needle, an optical fiber incorporated onto the probe needle, wherein a proximal end of the optical fiber is connected to a light source and a distal end of the optical fiber projects illumination light from the light source over a tip of the probe needle； and an adjustment mechanism that varies the illumination light between a first beam having a first numerical aperture that facilitates vitreous visualization and a second beam having a second numerical aperture that facilitates background illumination, wherein the second numerical aperture is larger than the first numerical aperture.
