The hang-back recession is a simple, safe alternative to conventional recession. We evaluated the surgical results in 23 consecutive patients undergoing bilateral hang-back lateral rectus recessions and 24 consecutive patients undergoing bilateral conventional lateral rectus recessions. The 6-week postoperative success rate was 78% in the hang-back group and 75% in the conventional group. At the time of the most recent follow-up, the success rate was 64% in the hang-back group and 85% in the conventional group. Dose-response curves were similar for both methods. There were more late overcorrections with the hang-back technique. We suggest modified surgical guidelines for the hang-back recession technique.
后徙式后退术是一种简单、安全的替代传统后退术的方法。我们评估了连续23例接受双侧后徙式外直肌后退术患者和连续24例接受双侧传统外直肌后退术患者的手术结果。术后6周，后徙式组成功率为78%，传统组为75%。在最近一次随访时，后徙式组成功率为64%，传统组为85%。两种方法的剂量反应曲线相似。后徙式技术导致的晚期过度矫正更多。我们建议对后徙式后退术技术进行改良的手术指导原则。
