Fig. 2

Bland-Altman plots of the agreement between Placido + SD-OCT and SS-OCT for total WTR/ATR astigmatism (a), total oblique astigmatism (b), total oblique trefoil (c), total vertical coma (d), total horizontal coma (e), total horizontal trefoil (f), total SA (g), and total RMS HOA (h). Solid lines indicate mean difference; dashed outer lines indicate 95% limits of agreement. SD-OCT, spectral-domain optical coherence tomography; SS-OCT, swept-source optical coherence tomography; WTR, with-the-rule; ATR, against-the-rule; SA, spherical aberration; RMS, root mean square; HOA, higher-order aberrations
