Abstract

Aim:To evaluate ocular surface changes in operated eye and compare it with non operated eye post strabismus surgery

Materials and Methods:A total of 50 patients with exotropia underwent unilateral squint correction surgery for exotropia. Dry eye evaluation including TBUT and Schirmer test were done preoperatively and after 1 month postoperatively.

Results :The mean Schirmer and TBUT in the operated eye and unoperated eye preoperatively was 17.5 +/- 6.4 mm, 19.4 +/- 9.2 seconds and 17.9 +/- 9.6 mm, 20.5 +/- 8.9 seconds respectively. Postoperatively mean Schirmer and TBUT values in the operated and unoperated eye was 13.7 +/- 7.4 mm, 14.5 +/- 8.1 seconds and 18.1 +/- 10.1 mm and 21.2 +/-9.2 seconds respectively. This difference between preoperative and postoperative change in Schirmer and TBUT value was statistical significant.

Conclusion: After strabismus surgery, most of the patients do have tear film instability.
