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.
