In summary, 22 patients have been presented who have undergone lateral rectus recessions ranging from 8 to 14 millimeters. The overall cosmetic success rate (plus or minus 15 diopters of orthophoria) was 77%. Eight of these patients had unilateral recession-resection procedures. Surgically created incomitance ranged from 3 millimeters to 6 millimeters and correlated only poorly with the amount of surgery performed. None of the patients complained of cosmetic or symptomatic effects of the lateral incomitancy induced. We have restricted surgery of the large angle exotrope to a single, two-muscle procedure, thereby decreasing patient morbidity. It is therefore our recommendation that surgery for large angle exotropia be restricted to two horizontal muscles.
总之，本文介绍了22例接受了8至14毫米外直肌后徙术的患者。总体美容成功率（隐斜视在正负15棱镜度范围内）为77%。其中8例患者接受了单侧后徙-切除术。手术造成的眼外肌不平衡范围为3毫米至6毫米，与手术量的相关性很差。所有患者均未抱怨所诱发的外直肌不平衡带来的美容或症状性影响。我们已将大角度外斜视手术限制为单一的双肌肉手术，从而降低了患者的发病率。因此，我们建议大角度外斜视手术应限于两条水平肌肉。
