Consecutive ET is iatrogenic in nature and is due to an overcorrection of which deviation during strabismus surgery?

Explanation:
Consecutive esotropia after strabismus surgery happens when the correction for an outward deviation is overshot. In exotropia the eye drifts outward, and surgery often weakens the lateral rectus or strengthens the medial rectus to bring it back toward alignment. If this adjustment is excessive, the eye is pulled too far medially in primary gaze, resulting in an inward turn, i.e., esotropia. This iatrogenic outcome specifically stems from overcorrecting the outward deviation. Vertical misalignments like hyperdeviation or hypodeviation are not the issue here.
