Objective:
The aim of this study is to determine the mean CCT among a normal Iraqi population and to cor-
relate between CCT and age, gender, refraction and corneal curvature.
Patients and methods:
This cross-sectional study was carried out at Ibn Al-Haitham Teaching Eye Hospital.
A total of 418 eyes from 209 healthy individuals with an age range from 20 to 75 years were studied. CCT was
measured by ultrasound pachymeter. Refraction was measured using an auto-refractor and confirmed by trial
lenses and retinoscopy to calculate the spherical equivalent. Corneal curvature was measured using an au-
to-refracto-keratometer to calculate the average corneal curvature (AVK).
Results:
The mean CCT was 543.95±32.58 μm with a range from 422 to 636 μm. CCT was not affected by gen-
der. CCT significantly negatively correlated with age and AVK. CCT significantly positively correlated with the
spherical equivalence.
Conclusion and recommendation:
Among an Iraqi population, CCT significantly decreased with age. Myo-
pics had significantly thinner corneas. There was weak but significant negative correlation between CCT and
corneal curvature. We recommend further studies about the relationship between central corneal thickness
and other ocular parameters in Iraqi population such as the axial length.
