Femtosecond PK yields good visual results with various suture patterns

FORT LAUDERDALE, Fla. — Femtosecond laser-assisted penetrating keratoplasty produced good visual outcomes with moderate astigmatism, according to a poster presentation here.
"In patients with 20/20 potential [visual acuity], mean [best corrected visual acuity] was better than 20/40 at all time points, regardless of suture pattern," Wenxin Wei, MD, and colleagues said in the poster presented at the Association for Research in Vision and Ophthalmology meeting.
The retrospective review included 162 eyes that underwent femtosecond PK, and 148 were included in the analysis; 13 eyes received 16 interrupted sutures (Group A), 14 eyes received a 16-bite running suture with eight interrupted sutures (Group B), and 121 eyes received a 24-bite running suture (Group C).
Six months after surgery, mean topographical astigmatism was 3.3 D in Group A, 3.4 D in Group B and 3.0 D in Group C, the poster said.
The authors noted several study limitations, as patients with corneal neovascularization were more likely to receive interrupted sutures, and patients with postoperative complications had more follow-up visits. Other limitations included the retrospective design and uneven sample size.
