1) After all the conditions are set, touch the "OK" button (2). Statistical
processing is performed and the result appears on the right side of the
screen.
The histogram (3) in the upper section shows registered lens constants and
the statistical processing results of those lens constants. When lens
constants are not registered, the result does not appear.
- Registered lens constant
- Histogram of predictive error in refractive power
- Average of predictive error in refractive power (Avg)
- Standard deviation of predictive error in refractive power (SD)
- No. of data sets (n) The histogram (4) in the lower section shows the
average of lens constants optimized by statistical processing and predictive
results of processing when the average is used.
- Average (Avg) of optimized lens constant
- Histogram of predictive error in refractive power
- Average of predictive error in refractive power (Avg)
- Standard deviation of predictive error in refractive power (SD)
- Number of data (n)
- Percentage that predictive errors in refractive power fall under +/-0.5 [D],
+/-1.0 [D], or +/-1.5 [D]
2) Select an IOL power formula (5). Available formulae are as follows.
- Haigis standard formula
- Haigis optimized formura
- Hoffer Ⓡ Q formula
- Holladay 1 formura
- SRK-II formula
- SRK/T formula
- SRK SHOWA formura
- Shammas-PL formula
- SRK/T Double K formura
3) Click the "Update IOL Constant" button (6) to register the optimized lens
constant for the target manufacturer, model, physician, and formula. When
the button is touched, the IOL data change confirmation screen appears.
Click the "OK" button to complete registration.
4) Touch the "Setup" button (7) to re-set filter conditions.
5) Touch the "Print" button (8) to print the displayed results.
6) Touch the "Exit" button (9) to close the statistical processing screen.
