Polar Value Analysis of Low to Moderate Astigmatism with Wavefront-Guided Sub-Bowman Keratomileusis

Figure 2

(a) Correlation between the magnitude of anterior corneal astigmatism and posterior corneal astigmatism across the whole sample. (b) Correlation between the meridional polar value AKP of anterior corneal astigmatism and posterior corneal astigmatism across the whole sample. The solid black line represents linear regression.
