Purpose : The purpose of this study was to investigate the distribution of corneal asphericity of all ages in Koreans and changes in corneal asphericity according to age and gender.

Methods : A total of 317 people(317 eyes) were analyzed retrospectively. The refractive error was analyzed by the autorefractometer. The corneal asphericity and curvature were measured in the central 6 mm zone of the cornea and analyzed by a rotating scheimplug camera.

Results : The anterior and posterior corneal Q-values were -0.17¡¾0.18(ranged -0.84 to 0.72) and -0.11¡¾0.29(ranged -0.89 to 1.27), respectively. As the age group increased, the anterior corneal Q-value did not show a significant difference(p=0.359), while the posterior corneal Q-value showed statistically significant differences of 0.01¡¾0.18, 0.10¡¾0.29, -0.12¡¾0.22, -0.20¡¾ 0.25, -0.27¡¾0.20 and ?0.33¡¾0.31 in the 30s, 40s, 50s, 60s, 70s and over 80¡¯s, respectively(p£¼0.001). The posterior corneal Q-value was negatively correlated with the age(r=-0.480, p£¼0.001).

Conclusion : The anterior corneal Q-value did not show a significant difference in gender and age while the posterior corneal Q-value changed from oblate to prolate shape as the age increased.
