Metrics used to evaluate the performance of AMARIS laser systems, with their description, Typical Values and their impact on performance.

Metric Description Typical Value (Units) Impact
Nominal fluence HF Calibrated spot depth of high energy pulse (1.0 mJ) 710 nm Lower values result in more pulses for a given treatment →
Over correction
Nominal fluence LF Calibrated spot depth of low energy pulse (0.7 mJ) 570 nm Lower values result in more pulses for a given treatment →
Over correction
Nominal pulses HF Calibrated number of high energy pulses required to go through the test material (PET) 12,300 pulses Lower values result in more pulses for a given treatment →
Over correction
Nominal pulses LF Calibrated number of low energy pulses required to go through the test material (PET) 10,330 pulses Lower values result in more pulses for a given treatment →
Over correction
Mean Performance Ratio between achieved and attempted refractive correction on test material (PMMA) 100% Lower values →
Under correction
Standard Deviation Standard deviation of the achieved vs. attempted refractive correction on test material (PMMA) <4.0% Lower values →
Less variability
Technical Performance Ratio between actual and theoretical performance on test material (PMMA) 100% Lower values →
Under Performance
