Fig. (3) This digital thermal camera image of the phacoemulsification probes and test sleeves was obtained 120 seconds after power application in Experiment 1. The Alcon Legacy probe, operating in pulse mode at 100% power, achieved a peak temperature of 120°F. The AMO Sovereign probe, operating in WhiteStar C/F pulse mode at 100% power, achieved a peak temperature of 164°F. These data points are bar graphed in the bottom panel of Fig. (5).
