Small incision lenticule extraction (SMILE) was introduced in the recent decade for the treatment of myopia and myopic astigmatism. This flap-free technique has a high efficacy and safety profile and also carries potential advantages over laser in situ keratomileusis such as a better corneal biomechanical stability, reduction in dry eyes rate, and the avoidance of flap complications. However, there have been concerns regarding the precision of astigmatism correction that undercorrection has been reported to be apparent. Various factors that affect astigmatism correction have been identified in the literature. The purpose of this review is to discuss the factors that affect astigmatism correction in SMILE and several techniques to improve the refractive outcomes.
微切口透镜切除术 (SMILE) 是近年来用于治疗近视和近视散光的一种方法。这种无瓣技术具有高效和安全的特点,并且相对于激光原位角膜磨镶术 (LASIK) 具有潜在优势,例如更好的角膜生物力学稳定性、干眼症发生率降低以及避免瓣并发症。然而,人们对散光矫正的精确性存在担忧,据报道,这种手术存在明显的欠矫现象。文献中已经确定了影响散光矫正的各种因素。本文的目的是讨论影响 SMILE 散光矫正的因素以及几种改善屈光效果的技术。
