Abstract: : Purpose:To evaluate the safety profile, power capabilities and clinical viewing value of various band pass filters on a new Xenon endoilluminator for vitreoretinal surgery Methods:Various band pass filters were inserted into the new Xenon light source from Synergetics. The resulting chromatic curves and aphakic retinal hazard functions were evaluated using a spectrophotometer. The power capablities were measured using a power meter. The filters were used intraoperatively to determine their clinical effectiveness. Results:The aphakic retinal hazard function of the Xenon light tested progressively improved as increasing wavelngth band pass filters were inserted. The increased safety profile allows power levels to be increased 10X without any increased phototoxicity risk. The band pass filter that provided the maximal luminance contrast and chromatic contrast created a significantly yellow viewing environment. Conclusions:The use of a yellow band pass filter to filter out UV light on a Xenon endoilluminator creates an increased safety profile allowing greater illumination levels to be used to maximize luminance contrast and the vitreoretinal surgery viewing environment.
