Abstract Details

Purpose:

To present the application of femtosecond laser-assisted elliptical LASIK flap in the management of post- arcuate keratotomy (AK) residual astigmatism.

Setting:

Department of Cornea and Refractive Surgery, Hopital Ophtalmique Jules-Gonin, Lausanne, Switzerland

Methods:

The procedure was performed using the elliptical flap mode software of femtosecond laser Femto LDV (Ziemer Ophthalmic Systems, Port, Switzerland) in an 82-year-old male with post- arcuate keratotomy residual astigmatism in the right eye. An elliptical LASIK flap with a nasally based hinge was created to avoid intersection of flap planar cut with the arcuate incisions. The short flap diameter was placed along the meridian of the incisions and the long diameter in the perpendicular meridian. The ablation pattern was adjusted to remain within the limits of the exposed stromal bed and take advantage of the elliptical flap shape.

Results:

No intraoperative or postoperative complications were encountered. The manifest refraction improved from +3.25 -5.50 x 125 preoperatively with an uncorrected visual acuity (UCVA) of 20/50, to -0.75 x 7 one month postoperatively, with a UCVA of 20/25. No AK incision-related flap complications were observed.

Conclusions:

Femtosecond laser-assisted elliptical LASIK flap creation is a safe and effective technique for the management of astigmatism in eyes with previous arcuate keratotomy incisions.
