Original papers: Does strabismus surgery induce significant changes of corneal topography?

To determine whether strabismus surgery significantly influences corneal curvature, corneal topography was measured in 68 patients before and both one day and three months after strabismus surgery. With few exceptions, early corneal topographic changes were moderate, statistically not significant and nearly disappeared after 3 months. Long term absolute astigmatism increased not significantly by 0.16 D. Our results demonstrate that strabismus surgery can induce transitory but usually no long term changes of corneal topography. Patients should be informed, however, that in rare cases an induced astigmatism may persist.
