Images of the same left eye in pharmalogically and naturally dilated states. Here (A) represents pharmacologically dilated state (Neo-Synephrine 2.5%) and (B) represents natural undilated state. The edges of the limbus and dilated pupil are illustrated using solid white and solid dark gray lines respectively, while that of the undilated pupil is denoted using a dashed light gray line. Limbus, dilated pupil, and undilated PCs are represented by white, dark gray, and light gray circles, respectively. A customized ablation in this eye could be decentered due to a slight superotemporal shift from when aberrations were measured over a dilated pupil to when they were corrected over an undilated pupil.
