The goals of successful strabismus surgery include the optimization of binocular potential through the establishment, reestablishment, or improvement of ocular alignment leading to a reduction or resolution of diplopia, as well as an improvement of compensatory head position or cosmesis. Fortunately, the incidence of new postoperative diplopia in patients without diplopia prior to strabismus surgery is extremely uncommon (less than 2%). Alternatively in a patient with preoperative diplopia that persists postoperatively, it is important to establish whether the diplopia is unchanged, increased, or of the same magnitude but shifted to a more disruptive position of gaze. During preoperative planning, the surgeon tries to anticipate and thus avoid postoperative diplopia. If the postoperative diplopia is unexpected, then a dispassionate evaluation of the outcome to identify planning, mechanical, or other factors is necessitated. These factors will be explored below systematically in the preoperative, intraoperative, and postoperative phases.
成功的斜视手术目标包括通过建立、重建或改善眼位来优化双眼视功能，从而减少或消除复视，并改善代偿性头位或美容效果。幸运的是，在斜视手术前没有复视的患者中，新的术后复视的发生率极低（低于 2%）。相反，对于术前有复视且术后持续存在的患者，重要的是要确定复视是否不变、增加或相同程度但移位到更具干扰性的注视位置。在术前规划中，外科医生试图预测并因此避免术后复视。如果术后复视出乎意料，那么需要客观评估结果，以确定是否存在规划、机械或其他因素的问题。下面将系统地探讨这些因素在术前、术中和术后阶段的作用。
