Comparisons of residual astigmatism, and higher order aberrations between the Artisan and Artiflex groups 5 years postoperatively.
| Artisan Group (mean ± SD) | Artiflex Group (mean ± SD) | P Value | |
|---|---|---|---|
| Number | 11 cases 11 eyes | 15 cases 15 eyes | − |
| Residual astigmatism (diopter) | −0.68 ± 0.53 | −0.55 ± 0.40 | 0.474 |
| J0 component of residual astigmatism (diopter) | 0.10 ± 0.28 | 0.01 ± 0.27 | 0.198 |
| J45 component of residual astigmatism (diopter) | 0.11 ± 0.30 | 0.02 ± 0.22 | 0.357 |
| Cornea THOA (µm)* | 0.05 ± 0.02 | 0.05 ± 0.03 | 0.643 |
| Internal THOA (µm)* | 0.07 ± 0.03 | 0.06 ± 0.02 | 0.238 |
| Ocular THOA (µm)* | 0.08 ± 0.04 | 0.06 ± 0.02 | 0.216 |
SD = standard deviation; THOA = total higher-order aberrations, root mean square (RMS) of the third- to sixth-order Zernike coefficients. *Pupillary diameter = 4 mm (Artisan group [10 cases 10 eyes], Artiflex group [15 cases 15 eyes]). Data were analyzed using the Mann-Whitney U Test.
