The procedure of small incision lenticule extraction (SMILE) was introduced in 2011, and since then there has been an increase in the number of cases undergoing this procedure worldwide. The surgery has a learning curve and may be associated with problems in the intraoperative and postoperative periods. The intraoperative problems during SMILE surgery include the loss of suction, the occurrence of altered or irregular opaque bubble layer and black spots, difficulty in lenticular dissection and extraction, cap perforation, incision-related problems, and decentered ablation. Most of the postoperative problems are similar as in other laser refractive procedures, but with decreased incidence. The identification of risk factors, clinical features, and management of complications of SMILE help to obtain optimum refractive outcomes.
小切口微透镜取出术（SMILE）于 2011 年推出，此后，全球接受该手术的病例数量有所增加。该手术具有学习曲线，可能与术中及术后期间的问题相关。SMILE 手术过程中的问题包括吸力丧失、改变或不规则不透明气泡层和黑斑的出现、晶状体分离和提取困难、盖穿孔、切口相关问题和离焦消融。大多数术后问题与其他激光屈光手术相似，但发生率降低。SMILE 并发症的危险因素、临床特征和处理方法的确定有助于获得最佳的屈光效果。
