Abstract
This study investigated, using the Orbscan II topography system, the
influence of age and sex related changes on the corneal thickness and anterior
corneal curvature, more specifically the fine structure of the cornea, in a Korean
young population. The Orbscan II topography system is a computer-assisted slit-beam
scanning technology that can map the anterior section of the cornea. The mean
central corneal thickness of all subjects was 547.532±44.529 µm. There
was no statistical difference (p>0.5) in the mean central corneal thickness between
males and females. Sex and age related changes in the mean central corneal thickness
had no specific statistical difference (P>0.5). There was a negative correlation
between the anterior corneal curvature and the central corneal thickness in all
subjects, except for the twenty year olds. However, the thickness relationship
between the mean central corneal and the eight paracentral corneal thicknesses had
strong statistical differences in all subjects. Also age and sex related changes in
the central corneal thickness and the anterior corneal curvature in all subjects had
no statistically significant difference, except from 20-26 years old (p>0.05). This
information could be a suitable reference basis for future studies in the young
population of Asia and for the development of examination tools for corneal
refractive surgery.
