[The influence of eye movements on monochromatic wavefront aberrations].
BACKGROUND
Wavefront-guided corneal surgery is a standard therapeutic option for correcting refractive errors. If the wavefront measured preoperatively is influenced by an incorrect alignment of the bulb, the ablation profile could be distorted and the quality of vision reduced.


METHODS
Wavefront analysis was done on 49 eyes, examining the primary gaze of the bulb as well as abduction, adduction, elevation, and depression.


RESULTS
The study demonstrated a significant influence of eye movements on astigmatic aberrations. Horizontal eye movements have a stronger influence than vertical ones do. Adduction especially leads to changes; here, RMS showed a significant difference.


CONCLUSIONS
Eye movements have a significant effect on wavefront profiles. The amount of aberration induced is generally very low. In individual cases, the numbers of aberrations induced by eye movements are in ranges reported to reduce the postoperative quality of vision when the ablation profile is taken into account.
