Wavefront analysis using a 6.5 mm pupil diameter (mean and SD) in laser in situ keratomileusis (LASIK) and in fellow photorefractive keratectomy with mitomycin C (MMC-PRK) eyes 1 year after surgery
| Total RMS* | Defocus* | Astigmatism* | HOA* | Coma | Spherical* | Other* | |
| LASIK | 1.15 (0.37) | 0.75 (0.45) | 0.36 (0.29) | 0.66 (0.19) | 0.32 (0.17) | 0.43 (0.20) | 0.33 (0.13) |
| MMC-PRK | 0.91 (0.30) | 0.57 (0.35) | 0.25 (0.18) | 0.58 (0.24) | 0.29 (0.20) | 0.39 (0.21) | 0.26 (0.12) |
HOA, higher-order aberrations until the fifth order; Other, higher-order aberrations until the fifth-order RMS other than coma and spherical aberration; RMS, root mean square; Spherical, spherical aberration.
*Statistically significant differences between groups. Forty-two patients completed follow-up.
