Comparison of ocular biometry among the three astigmatism change subgroups.
| Ocular parameter | Astigmatism subgroups | F | P value | ||
|---|---|---|---|---|---|
| Increase | Decrease | No change | |||
| Baseline AL (mm) | 23.33 ± 0.98∗# | 22.89 ± 0.84 | 23.06 ± 0.75 | 74.562 | <0.001 |
| AL change (mm) | 0.68 ± 0.41∗# | 0.56 ± 0.36 | 0.53 ± 0.33 | 16.466 | <0.001 |
| Baseline AL/CRC ratio | 2.99 ± 0.08∗# | 2.94 ± 0.08 | 2.93 ± 0.08 | 45.005 | <0.001 |
| AL/CRC ratio change | 0.08 ± 0.06∗# | 0.07 ± 0.04 | 0.07 ± 0.04 | 9.312 | <0.001 |
| Baseline SER (D) | −0.63 ± 1.40∗# | −0.07 ± 1.04 | −0.01 ± 0.74 | 39.142 | <0.001 |
| SER change (D) | −0.86 ± 1.15∗# | −0.31 ± 0.86 | −0.39 ± 0.77 | 33.222 | <0.001 |
AL, axial length; CRC, corneal radius of curvature; SER, spherical equivalent refraction; D, diopters; values are means ± standard deviations. ∗Compared to the decrease subgroup, P < 0.001; #compared to the no-change group, P < 0.001.
