Mean (SD) decomposed vectors measured by manual keratometry for 16 eyes following microtrabeculectomy
| WTR | ATR | p Value | |
|---|---|---|---|
| Month 1 | 0.52 (0.29) | 0.16 (0.27) | 0.026 |
| Month 3 | 0.22 (0.25) | 0.16 (0.31) | 0.28 |
| Month 6 | 0.23 (0.22) | 0.29 (0.39) | 0.50 |
| Month 12 | 0.24 (0.27) | 0.31 (0.31) | 0.33 |
WTR = with the rule astigmatism (vertical steepening) measured in dioptres; ATR = against the rule astigmatism (vertical flattening) measured in dioptres. p = Wilcoxon signed rank p value.
