  • Page 104: Light Probe Settings

    Prolonged exposure to the light emitted from this accessory device increases the risk of ocular damage. However, insufficient light intensity may result in inadequate visualization and adverse effects more serious than retinal photic damage or photoretinitis. Alcon recommends setting illumination levels to the minimum level necessary to perform the function.

  • Page 105: Light Projection And Intensity

    Light Projection and Intensity Each light probe port can be set to a different level of brightness or intensity. However, Alcon recommends lowering the intensity settings of disabled probes to avoid sudden changes in light output (for instance, going from low output to high output) when switching between probes.
  • Page 106 Spectrally-Weighted Aphakic Irradiance Aphakic irradiance was determined using fiber optic light probes approved for use with the console. The value for spectrally-weighted aphakic irradiance (SWAI) was determined with an effective 3 mm diameter aperture at a distance of 5 mm in a plane perpendicular to the radiating light probe tip. Output Limits To avoid potentially unsafe operation of the system, the console warns users or prevents operation when certain thresholds are exceeded.
