ABSTRACT
ABSTRACT: Purpose: Evaluation of effects of recession strabismus surgery on corneal topography. Methods: In this study, in Istanbul Beyog˘lu Educational and Research Eye hospital, we evaluated the variation of corneal topography after medial or lateral rectus muscle recession by using a computer assisted topographic analysis system. 46 eyes of patients, with only one horizontal rectus recession opreation, were evaluated before and 1 week and 1 month after surgery. Results: One week after the operation, there was a steepness of 0,00-1,75 Diopter (D) in vertical axis (med. 0,35 D) and after the first month the change on average was 0,10 D (p 0,05). Conclusion: We concluded that, since after the first month, the effect of rectus muscle recession operations on corneal astigmatism decrease and return back to the old level, recession operations do not have a practical effect on refractive value of the eye.
