Table 1.
Astigmatism before and after cycloplegia.
Table 2.
Demographic characteristics between the validation study and the main study.
Table 3.
Percentage of TA, CA, and ORA by different criteria and gender.
Table 4.
Percentage of different types of axes of astigmatism greater than or equally 1.00D.
Table 5.
The axis relationship between ocular residual and corneal astigmatism.
Fig 1.
Proportion of the three types of axis relationships between CA and ORA in different levels of TA.
On-axis: axis difference between the ORA and CA of 0 ± 10°, opposite-axis: axis difference of 90 ± 10°, with the remaining considered as oblique-axis.
Table 6.
Compensation factor for the relationship between ocular residual and corneal astigmatism.
Fig 2.
Correlation between CA and ORA in (A) J0 and (B) J45. There was a statistically significant correlation between these two sources of astigmatism for both vectors. J0 = Jackson cross-cylinder power at axis 0° and 90°; J45 = Jackson cross-cylinder power at axis 45° and 135°.
