The timers in the upper left corner indicate Effective Phaco Time (EPT), Ultrasonic
(U/S) Time in Footpedal Position 3, and Ellips EPT if Ellips™ Technology is On.
Effective Phaco Time is ultrasound time as a weighted total that takes into account
the amount of power being used:
• at 100% power: 1 sec. U/S Time = 1 sec. EPT
• at 50% power: 1 sec. U/S Time = .5 sec. EPT

1. Select a shorter time interval to adjust the Time Line Duration and to see
greater case details. For example, 10 Sec shows more detail than 15 Min.
2. Select a longer time interval for an overview of the surgery or sessions, such as
1 hour or 2 hours. This view provides less detail, but gives you a better
indication of the trends over a period of time. Use the << or >> buttons to
change the time intervals. You cannot use the arrow buttons when you view an
active case.
