The average of preoperative corneal astigmatism was 1.63 ± 0.886D, decreased to 0.53 ± 0.628D in the third month after surgery and stable to 5 years. Surgically induced astigmatism was 1.09 ± 0.413D, which indicated under-correction. However, no complications were recorded.Conclusion: The femtosecond laser-assisted cataract surgery is safe and long effective in correcting the corneal astigmatism in patients with preexisting corneal astigmatism.Keywords: femtosecond laser, corneal astigmatism, cataract, arcuate incision
