The study compared three surgical methods for the correction of myopia with astigmatism: SMILE, FS-LASIK, and TICL implantation in 159 patients (51 eyes in the SMILE group, 53 in FS-LASIK, and 55 in TICL).[1] Three months after surgery, the residual cylinder error was the lowest in the SMILE (-0.21 ± 0.25 D) and FS-LASIK (-0.30 ± 0.23 D) groups compared with TICL (0.6 ± 0.23 D), indicating that SMILE achieved the best astigmatic correction accuracy.[1] However, the TICL group showed lower surgically induced astigmatism and fewer errors than the SMILE and FS-LASIK groups, especially when correcting against-the-rule and oblique astigmatism.[1] In terms of optical quality, TICL produced significantly less higher-order aberrations, coma, and spherical aberrations than both laser methods.[1] All three methods have been shown to be effective for correcting mild to moderate myopia with astigmatism ≥1.0 D.[1] The conclusion of the study suggests that SMILE provides the best accuracy of astigmatic correction, while TICL offers better optical quality with less aberrations.[1]
