Abstract

Introduction: Keratoconus is a chronic, noninflammatory, progressive, ectatic corneal disorder
that degrades vision due to myopia and irregular astigmatism. Recently, the priority of posterior
corneal astigmatism has been identified when toric IOL is considered. The aim of the study was
to assess and correlate the power and axis orientation of anterior and posterior corneal astigmatism in keratoconus patients and healthy controls. Patients and methods: This was a
retrospective cross sectional comparative study which involve 100 eyes of 50 KC patients and
100 eyes of 50 control group. Which they have a scans of corneal tomography maps of goodquality that analyzed by pentacam. Results: The mean magnitudes of the ACA and PCA in KC
group were higher than controls and the axis orientation of corneal astigmatism was 71% WTR
for ACA and 73% ATR for PCA and there were significant correlations between ACA and PCA
with TCA, the effect of ACA on TCA was 6.1% and of PCA on TCA was 9.2%. Conclusion: In
KC magnitudes of the ACA and PCA were significantly higher than controls, and we found a
significant correlation between the magnitudes of ACA, PCA to the magnitudes of TCA in both
groups. The axis orientations of the ACA and PCA were WTR and ATR, respectively in most of
KC cases.
