17 Holladay Report & Holladay EKR65 Detail Report
Figure 164: Holladay EKR65 Detail Report of a post LASIK exam
The EKR65 mean is 35.63 D at the 4.5 mm zone and 35.27 D at the 3.0 mm zone (Figure 164).
The pupil diameter was 2.94 mm and confirmed with scotopic pupillometry done with another device.
Due to the small pupil, the appropriate Ks for IOL calculation would be at the 3.0 mm zone and
are EKR65 flat K1 = 35.23 A 146° and EKR65 steep K2 = 35.30 A 56°. The axes are quite different
from the 4.5 mm zone, but this is due to the small magnitude of the astigmatism and is seen in the
segmented semi-meridian lines in the axial and tangential maps.
