Summary

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.

Conditions

  • Cataract
  • Astigmatism

Interventions

PROCEDURE

Femtosecond laser arcuate keratotomy

The patient will receive femtosecond laser arcuate keratotomy and femtosecond laser-assisted cataract surgery with implantation of a monofocal intraocular lens in one eye.

PROCEDURE

Toric intraocular lens implantation

The patient will receive femtosecond laser-assisted cataract surgery with implantation of a Toric monofocal intraocular lens in the contralateral eye.
