Abstract Details

Purpose:

To report the initial results of intrastromal arcuate keratotomy performed with a femtosecond laser to treat corneal astigmatism during FLACS

Setting:

Pentagram Eye Hospital, Sofia, Bulgaria

Methods:

Patients with corneal astigmatism (naturally occurring) were treated with a VICTUS femtosecond laser platform to perform paired AK on the steep axis completely placed within the corneal stroma. Patients were followed for 6 months after surgery. Preoperative and postoperative (1-day, 1-week, and 1-, 3-, and 6-month) examinations included corrected and uncorrected visual acuities, manifest refraction, endothelial cell count, corneal pachymetry and corneal topography.

Results:

The study enrolled 15 patients. No corneal perforations occurred, and all incisions were placed at the planned locations. After a 6-month follow-up, the mean refractive cylinder was reduced from 1.71 diopters (D) ± 0.63 (SD) to 0.28 ± 0.39 D (P<.001). The mean topographic astigmatism was reduced from 1.80 ± 0.53 D preoperatively to 0.51 ± 0.28 D at 6 months (P=.002). There was excellent refractive and topographic stability over time. The endothelial cell density was unchanged significantly. Patient satisfaction was very high.

Conclusions:

The femtosecond laser allowed the effective creation of precise, purely intrastromal, arcuate incision patterns with an excellent safety profile, rapid recovery, and stability of vision without the known risks associated with incisions that penetrate Bowman membrane and are near to Descemet membrane. The femtosecond laser enables predictable, and effective corneal incisions for use in AK to correct corneal astigmatism in range of 2.50 Dpt.
