In modern cataract surgery, residual astigmatism continues to be one of the major factors influencing patients' visual quality and satisfaction. The goal of this study is to compare the clinical outcomes of femtosecond laser arcuate keratotomy in one eye and Toric intraocular lens implantation in the contralateral eye for astigmatism correction in patients undergoing femtosecond laser-assisted cataract surgery. The study is a prospective randomized comparative study. Patients with binocular regular corneal astigmatism ranging from 0.75 to 3.00 D will be recruited. The patient will randomly receive femtosecond laser arcuate keratotomy in one eye and receive Toric intraocular lens implantation in the contralateral eye. Long term evaluation will be performed to compare the visual acuity, subjective manifest refraction, and corneal topography between groups.

Inclusion Criteria:

• cataract patients
• patients with binocular regular corneal astigmatism ranging from 0.75 to 3.00 D
• patients who plan to receive femtosecond laser-assisted cataract surgery

Exclusion Criteria:

• patients with ocular surface abnormalities such as irregular corneal astigmatism, corneal scarring, keratoconus, and pterygium)
• patients with history of ocular trauma or surgery
• patients with coexisting ocular disorders such as glaucoma, retinal vascular occlusive disease, retinal detachment, diabetic retinopathy, and any optic nerve-related pathologies
• patients with concurrent severe systemic diseases
• patients who lack of cooperation

There is not a plan to make IPD available.
