BERLIN — The decagonal-shape cut is becoming increasingly popular for femtosecond laser-assisted penetrating keratoplasty.
"It is the best for stability. There is no decentration or rotation during suturing, and adherence is perfect," Mark Tomalla, MD, said at the European Society of Cataract and Refractive Surgeons meeting here.
In addition, fixation sutures and double sutures are no longer necessary, he noted, and preliminary patient data seem to confirm less astigmatism, quicker wound healing and improved uncorrected visual acuity.
Hélène Proust, MD, said she uses femtosecond PK with decagonal cuts in her clinic in France. She applies single sutures at each angle.
"Visual results are very good, with less induced astigmatism, early rehabilitation and only one night of hospitalization. In some cases, we do it even in outpatient regimen," she said.
