SMILE屈光手术切削偏差的影响因素研究进展

Research Progress on Influencing Factors of Machining Deviation in SMILE Refractive Surgery

飞秒激光小切口角膜基质透镜取出术(SMILE)因其微创、无瓣、并发症少等优点已在国内外广泛应用。术前准确预测角膜基质切削深度及术后剩余角膜基质床厚度可以避免手术源性角膜扩张的风险,准确预测不同近视程度患者在术中实际切削深度是SMILE手术安全性和有效性的保障。本文将围绕SMILE手术切削偏差的影响因素进行综述。

Small incision lenticule extraction (SMILE) has been widely used at home and abroad due to its advantages of minimally invasive, valvular, and fewer complications. Preoperative accurate prediction of the depth of corneal stromal ablation depth and postoperative residual corneal stromal bed thickness can avoid the risk of operationally induced corneal dilatation. Accurate prediction of the actual depth of corneal ablation depth in patients with different myopia levels is the guarantee of the safety and effectiveness of SMILE. This article reviewed the influencing factors of SMILE ablation deviation.
