飞秒激光小切口角膜基质透镜取出术(SMILE)中眼球旋转是影响术后散光矫正效果的因素之一,显著的眼球旋转会引起术后散光欠矫、高阶像差增加等不良结果。因VisuMax飞秒激光系统缺乏眼球追踪及虹膜定位系统,增加了散光精准矫正的难度。精确测量眼球旋转度可以有效地指导手术的设计,提高手术的安全性和术后视觉质量。目前已有不同方法测量患者术中的眼球旋转并对其进行定位补偿。文章从屈光手术中的眼球旋转特点、SMILE手术眼球旋转定位补偿方法以及旋转补偿对SMILE术后效果的影响三个方面展开综述。

[Abstract]
Cyclotorsion of the eye is a factor that affects the accuracy of astigmatic correction after small incision lenticule extraction(SMILE), potentially leading to unexpected outcomes such as astigmatic undercorrection and an increase in higher-order aberrations. One possible explanation for these issues is the lack of active rotational tracking software in the VisuMax femtosecond laser system. Accurately measuring ocular cyclotorsion can effectively guide the design of the surgery and improve the postoperative visual quality. Several methods have been developed to measure and compensate for cyclotorsion during SMILE. This article reviews the characteristics of cyclotorsion in refractive surgery, the methods of cyclotorsion compensation, and the impact of cyclotorsion compensation on the outcomes of SMILE.
