Abstract

The aberrations demonstrate the changes in light direction when it passes through the eye’s optical system. Our study goal was to evaluate the impact of keratoconus apex’s localization on eye aberration. 79 eyes were analysed in our study by keratoconus stage and by apex localization. Vertical coma had a statistically significant difference p=0.03 (Mann-Whitney test) between first (1.4 μm) and third (3.9 μm) keratoconus stage. The mean spherical aberration in case of central apex was 0.6 μm and in case of peripheral apex was 1.0 μm (p=0.01). The keratoconic eyes have increased corneal aberrations comparing to normal eyes.
