Purpose: To study corneal topographical changes after strabismus surgery. Methods: Computer-aided corneal topography was used in 43 strabismus patients (45 eyes) one or two days prior to and six or seven days after strabismus surgery. The spherical and cylindrical equivalents were calculated based on the simulated keratome-try.Results: After the surgery, only the changes at 3mm in the inferior quadrant were statistically significant. The changes at 3mm in the rest quadrants and the changes at 7mm were not significant. Significant changes in spherical equivalent were found post-operatively. Neither the horizontal nor the vertical meridional equivalent showed significant changes after surgery.Conclusions: The results of corneal topographical changes following strabismus surgery in our preliminary study indicated the little effect of strabismus surgery on corneal curvature and corneal astigmatism.
