Tomey UD-8000 - Calculation

3-141 ■
3.7.1 Calculation
■ When using the result of biometry for calculation of the
IOL power, the physician must examine the
measurement result.
■ Calculation by UD-8000 may produce some errors due
to the number of significant digits in internal
calculations.
■
Complex numbers may be generated for the SRK/T
formula. In this case, the “√ section” is calculated as
zero and an asterisk “*” is shown on the right of the
calculation result.
This instrument automatically starts calculation and displays the result
when all items required for IOL calculation are set.
