Purpose
To evaluate the efficacy of femtolaser-assisted astigmatic keratotomy.
Setting
Methods
Twentytwo eyes of 11 consecutive patients with low to moderate degree of regular astigmatism (from 1 diopter to 2.25 diopters) entered this study. Paired arcuate keratotomies on the steep axis placed within the corneal stroma were performed at the time of routinary femtolaser-assisted cataract surgery. Preoperative and postoperative (3 and 6-month) examinations included corrected and uncorrected visual acuities, corneal topography and endothelial cell count.
Results
Sixty-eight percent of eyes attained a postoperative cylinder of less than 0.50 D. At 6-month, the mean refractive cylinder was reduced significantly from 1.52 diopters ± 0.41 to 0.50 ± 0.35 D, and the mean topographic astigmatism was reduced significantly from 1.60 ± 0.51 D preoperatively to 0.57 ± 0.28 D. No endothelial cell count decrease was observed.
Conclusions
The femtosecond laser-assisted intrastromal arcuate incision is a precise and safe procedure to manage corneal astigmatism during cataract surgery with a rapid recovery and stability of vision.
