Correlation between preoperative pupil size and low contrast VA or contrast sensitivity (Spearman’s correlation coefficient analysis).
| Correlation Coefficients | |
|---|---|
| 12.5% low contrast VA | 0.407 (p = 0.04) |
| 6.0% low contrast VA | 0.440 (p = 0.03) |
| Contrast sensitivity (3 cpd) | 0.26 (p = 0.19) |
| Contrast sensitivity (6 cpd) | 0.15 (p = 0.63) |
| Contrast sensitivity (12 cpd) | 0.452 (p = 0.02) |
| Contrast sensitivity (18 cpd) | 0.436 (p = 0.04) |
VA: visual acuity, cpd: cycles per degree.
