Diplopia following cataract extraction occurs in approximately 1% of cases or less. With over 1.5 million cataract extractions per year, this can lead to a considerable morbidity. It is typically a small vertical deviation and is distressing if unanticipated. The most common etiologies include surgical manipulation of orbital tissue from a bridle suture, extraocular muscle trauma from a retrobulbar needle or anesthetic, and unmasking an underlying strabismus or systemic condition with extraocular muscle involvement. Care must therefore be taken by obtaining a complete preoperative history and examination, document any preexisting strabismus and systemic condition, and avoid any direct extraocular muscle trauma or manipulation.
白内障摘除术后复视的发生率约为1%或更低。每年有超过150万例白内障摘除手术，这可能导致相当高的发病率。复视通常表现为轻微的垂直偏差，如果是意外发生则会令人苦恼。最常见的病因包括因缝线牵拉导致的眼眶组织手术操作、球后注射针或麻醉剂引起的眼外肌损伤，以及潜在斜视或眼外肌受累的全身疾病被暴露出来。因此，必须通过全面的术前病史采集和检查，记录任何已存在的斜视和全身疾病，并避免任何直接的眼外肌损伤或操作。
