NOTE: For ease of viewing, the EPT, EFX, UST, and DT times are in a large font size on the
End Case screen. The EFX shows only when you attach an ELLIPS FX or VERITAS
Swivel handpiece.
The EPT or EFX timer appears on the upper left side of the surgical screen. You can tap the
timer to view the detailed timer pop-up with EPT, EFX, UST and DT timers of the surgical
case. Each timer indicates the following:
• Effective Phaco Time (EPT). EPT 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 = 0.5 sec. EPT

Average phaco power (AVG) = EPT/UST
• Ultrasonic (U/S) time (UST) in foot pedal position 3
• EFX when you attach an ELLIPS FX or VERITAS Swivel handpiece
• DT – Diathermy Time
