- Strengthen Incylotorsion effect of the Superior Oblique without affecting vertical alignment
- Most useful with a functioning superior oblique and excyclotorsion present
- Can create 10-15 degrees of incyclotorsion
- The effect may wain 20-30% with time
Transpose the anterior 1/3 to 1/2 of the superior oblique tendon fibers to the superior border of the lateral rectus muscle. Fixate the tendon 8 mm posterior to and 2 mm superior to the superior border of the lateral rectus muscle. Tightening only the radially oriented fibers will avoid a significant change in vertical deviation but there may be an exoshift in down-gaze.
