Abstract Objective To investigate the effectiveness of topography-guided FS-LASIK in treating asymmetrical corneal astigmatism. Methods Forty-one patients (72 eyes) were prospectively enrolled in the study and were treated with FS-LASIK at the Daping Hospital. They were randomly divided into a T-CAT group (37 eyes) that underwent topography-guided FS-LASIK and a WF-optimized group (35 eyes) that underwent wavefront-optimized FS-LASIK. Preoperative and postoperative best corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), vertical coma (C7), horizontal coma (C8) and total third order coma were measured and the differences between the two groups were compared with paired t tests or independent t tests. Results The postoperative UCVAs of the T-CAT group and WF-optimized group were 5.03±0.05 and 5.00±0.05, respectively, and the difference was statistically significant (t=3.00, P<0.01). Postoperative vertical coma and total third order coma were significantly reduced in the T-CAT group (t=14.801, 8.429, respectively, both P<0.01), and were significantly lower than that for the WF-optimized group (t=-7.799, -6.737, P<0.05). Conclusion Topography-guided FS-LASIK can be an effective treatment for patients with asymmetrical corneal astigmatism. Treatment using this surgical technique significantly improved the visual acuity of patients.
