LCA840-561 as a function of age.
Dotted lines indicate the prediction intervals, and the dashed line indicates extrapolation of regression beyond the age range.
Fig 4.
The Cauchyʼs fittings for each average of LCA.
Fittings were plotted using the wavelength 590 nm as an offset wavelength. Dotted lines indicate extrapolations of regressions. Symbols indicate measured points for each IOL.

The results of HOA RMSx and total HOA RMS of each IOL type.
Fig 7.
The results of polychromatic MTF simulations with LCA but without HOA.
The results of Alcon, HOYA XY-1, and AMO IOLs with the power +20 D, and the average of phakic eyes.
Fig 8.
All polychromatic MTF results of IOLs.
Alcon (Left), HOYA XY-1 (Center), and AMO (Right) IOLs. Only the MTF in horizontal, with LEF considered, is shown in the figures.
Fig 9.
Results for phakic eyes that have three different degrees of HOA and results for eyes with Alcon’s IOL, HOYA XY-1’s IOL, and AMO’s IOL that have two different degrees of HOA for each manufacturer.
Fig 10.
The VSOTFs as a function of LCA840-561.
The VSOTFs were calculated by considering both HOA and LCA.
Fig 11.
The VSOTFs as a function of HOA RMS.
The VSOTFs were calculated by considering both HOA and LCA. The quadratic regressions for each manufacturer and for phakic eyes are also shown.

The results of reflectivity and interferometry.
When values from the manufacturers are available, they are provided in parentheses.
Fig 12.
The results of refractive index chromatic dispersion of IOLs.
Results correspond to the Cauchy’s equation coefficients in Table 5. Dotted lines indicate extrapolations.
Table 4.
The results of HSWA measurements for the artificial eye.
Table 5.
Cauchy’s equation coefficients of chromatic dispersion of the refractive index, refractive index of 555 nm and d-line, and Abbe’s number.
The chromatic dispersions were estimated by using the HSWA results of IOLs with the power +30 D.
Fig 13.
Calculated LCA and measured LCA with HSWA.
A Deming regression line is shown as a solid line and confidence intervals (α = 0.05) are shown as dashed lines. We acquired the ACD data for only 8 of 11 of Alcon’s IOLs, and the plot sizes were larger for the results using ACD data.

Comparison of our results with other researchers’ results corresponding to comparable spectral regions.
Table 7.
The LCA840-561 of each surface, total LCA840-561, corneal LCA840-561, and LCA840-561 of IOL were calculated for each kind of IOL with the paraxial approximation.
Table 8.
The LCA840-561 of each surface, total LCA840-561, corneal LCA840-561, and LCA840-561 of the lens were calculated for the Navarro schematic eye [39], the Le Grand schematic eye [18], and the modified Le Grand schematic eye with the paraxial approximation.
We changed the Abbe’s number of the lens from 50 to 45 for the Le Grand Schematic eye.
