Background and Objectives: Evaluation of anterior corneal surface aberrations according to normal corneal topography is important. In this study, aberrations of corneal anterior surface in eyes with normal topographic pattern, was comparatively investigated.

Methods: In this comparative study, 165 eyes of 97 patients (20-30 years old), which had normal corneal topographic pattern, were evaluated. Data collection tools were Pentacam topographer, Tomey topographer, standard Snellen visual acuity chart, and slit-lamp. Data were analyzed using Kolmogorov-Smirnov and Tukey post-hoc tests.

Results: Based on the results of the Kolmogorov-Smirnov, the distribution of all data was normal (0.058) HOAs) were higher in asymmetric bow-tie and irregular group compared to the other groups, and spherical aberration was significantly higher in the irregular pattern group compared to the other groups (p<0.001), except round pattern group (p=0.089).

Conclusion: The results of the present study showed that there is a significant relationship between corneal topographic patterns and corneal anterior surface aberrations, and according to the difference of some aberration components in subjects with normal topographic pattern, aberration analysis is essential to achieve higher visual quality after refractive surgery.

Keywords: Corneal wavefront aberrations, Topography, Medical, Refractive surgical procedures
