Small Incision Lenticule Extraction (SMILE) is a flap-free intrastromal technique for the correction of myopia and myopic astigmatism. To date, this technique lacks automated centration and cyclotorsion control, so several concerns have been raised regarding its capability to correct moderate or high levels of astigmatism. The objective of this paper is to review the reported SMILE outcomes for the correction of myopic astigmatism associated with a cylinder over 0.75 D, and its comparison with the outcomes reported with the excimer laser-based corneal refractive surgery techniques. A total of five studies clearly reporting SMILE astigmatic outcomes were identified. SMILE shows acceptable outcomes for the correction of myopic astigmatism, although a general agreement exists about the superiority of the excimer laser-based techniques for low to moderate levels of astigmatism. Manual correction of the static cyclotorsion should be adopted for any SMILE astigmatic correction over 0.75 D.
微小切口基质透镜切除术（SMILE）是一种无瓣的基质内技术，用于矫正近视和近视散光。迄今为止，该技术缺乏自动定心和旋转控制，因此人们对其矫正中度或高度散光的能力提出了一些担忧。本文的目的是回顾已报道的SMILE矫正圆柱镜超过0.75 D的近视散光的结果，以及与基于准分子激光的角膜屈光手术技术所报道结果的比较。共确定了五项明确报告SMILE散光结果的研究。尽管对于基于准分子激光的技术在低至中度散光方面的优越性存在普遍共识，但SMILE在矫正近视散光方面显示出可接受的结果。对于任何超过0.75 D的SMILE散光矫正，应采用手动矫正静态旋转。
