Notes: Preoperative and postoperative data are reported as the actual value, mean ± SD, or median (IQR).

Positive value = esodeviation; negative value = exodeviation.

Positive value = pass midline; negative value = before reaching midline.

Abbreviations: F/U, follow-up; NS, non-specified; PD, prism diopter; PF, posterior fixation suture; VRT, vertical rectus transposition.
