Fig. 2.

Changes in TCA (λ = 543 and 840 nm) with pupil displacement in the AOSLO for subjects 20075 (A-D) and 20076 (E-H). TCA was measured subjectively under different optical corrections: Defocus only (panels A and E), defocus and astigmatism (B and F), and all aberrations (C and G). Panels D and H show image-based TCA measurements following correction for all aberrations. The horizontal (blue rightward triangles) and vertical (gray upward triangles) components of the chromatic offset follow a linear relationship with the magnitude of the horizontal and vertical pupil offsets, respectively. Solid lines show fits to Eq. (2).
