Long-term results of hemihang-back lateral rectus recession.
OBJECTIVE
To report our long-term results with the hemihang-back technique for lateral rectus muscle recession in moderate- and large-angle exotropia.


METHODS
The medical records of 144 consecutive patients who underwent unilateral or bilateral hemihang-back lateral rectus recession between 1999 and 2002 were reviewed. The amount of surgery performed was based on the distance exotropic deviation. Surgical outcomes were analyzed for all patients included in the study.


RESULTS
A total of 66 patients met the inclusion criteria. Sixteen patients had undercorrection, but 6 of these patients redeveloped an exodeviation 6 months after the surgery. No overcorrections were observed in this study.


CONCLUSIONS
The hemihang-back technique is a safe and effective alternative to conventional lateral rectus recession in patients with moderate- or large-angle exotropia.
