Aim: The aim of this study is to compare the central corneal thickness between myopes, hyperopes and emmetropes of different age groups. Materials and Methods: The study involves 156 eyes: 60 emmetropic subjects, 44 myopic subjects (< -8.0 D) and 52 hyperopic subjects (<+4.0 D). The Central Corneal Thickness (CCT) was measured with an ultrasound pachymeter and all the data entered in Microsoft excel for the statistical analysis. Result: Mean CCT for myopic group (n=44) was 539.3 ± 30 µm, emmetropic group (n=60) was 536 ± 33 µm and hyperopic group (n=52) was 540 ± 49 µm. There were no statistically significant differences between the CCT’s of myopic, hyperopic and emmetropic eyes for different age groups. No significant correlations were found between CCT and the amount of spherical equivalent in hyperopes and myopes. Conclusion: There was no significant change in the CCT between myopes, hyperopes and emmetropes, and also no change in the central corneal thickness as the age progressed.
