| Apical-touch | Three-point-touch | p-Value | |||||||
|---|---|---|---|---|---|---|---|---|---|
| Baseline | 14 days | Dif. | Baseline | 14 days | Dif. | Time | Group | Time * group | |
| CCA (D) | 3.60 ± 2.04 | 3.28 ± 1.76 | 0.32 | 3.90 ± 1.58 | 3.21 ± 1.54 | 0.69 | <0.0001 | 0.808 | 0.176 |

CCA: central corneal astigmatism. D: diopters. RM-ANOVA: repeated measures analysis of variance.
