Except for high K readings around 50 diopters in both eyes indicative of corneal curvature myopia, her topography was otherwise normal and almost spherical with minimal corneal astigmatism of around < 0.50 diopters against the rule [Figures 1 and 2].

Figure 4 outside the 6 mm optic zone well outside and correlating with the mesopic pupil size of 4.96 mm for approximately 4 mm length perpendicularly on either side of the steep axis at 180  bisecting it for 2 mm on either side. Four radial cuts were placed again on the stromal bed as shown outside the optic zone such that the superior cuts were aligned on either side of the flap hinge.
