He was noted to have significant against-the-rule corneal astigmatism in both eyes (2.41D @ 10  OD, 2.40D @ 160  OS) preoperatively (Fig. 1).
Postoperative topography 4 months after the second eye showed resolution of OD astigmatism to 0.60D @ 37  while OS remained unchained at 2.1D @ 167 . Axis measurements were derived from Holladay report for accuracy (not pictured here)

After 4 months of observation, repeat topography revealed that his OD astigmatism had further shifted from the preoperative 2.41D @ 10  to postoperative 0.6D @ 37 , while his left eye changed only slightly from 2.4D @ 160 to 2.06D @ 167  (Fig. 2), without any topographical or clinical sign of corneal dystrophy.
