To evaluate the safety, efficacy, and clinical parameters in combined clear cornea DSAEK and AK surgery performed with the LenSx femtosecond laser (Alcon, Fort Worth, TX).
15 eyes of 13 consecutive patients who underwent combined DSAEK and AK were evaluated pre-operatively and 6 months post-operatively for: age, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refraction, cylinder (C), topographic cylinder change (TCc), endothelial cell count (ECC), and possible complications. The 3 host cornea incisions of 3.5 mm, 1.2 mm, and 1.2 mm, along with 2 partial thickness arcuate incisions at the 6mm optical zone, were performed by the laser. The arcuate incisions were adjusted manually at the slit lamp at 3 months.
The mean age was 68 years and mean values pre-operatively and post-operatively were respectively: UDVA: 20/400 and 20/40, CDVA: 20/100 and 20/25, C: -2.25 D and -0.55 D. The mean TCc was -2.45D. No complications were experienced during the follow-up period.
This novel bladeless femtosecond laser-assisted clear cornea combined DSAEK and AK surgery appears to be safe and effective in facilitating reproducible wound creation and corneal astigmatic reduction.
