Precisely Controlled Side Cut in Femtosecond Laser-Assisted Deep Lamellar Keratoplasty for Advanced Keratoconus

Abstract

The vacuum trephine remains as a major surgical tool for deep lamellar keratoplasty. The precise control of side cut in the diameter and depth in the FDLK procedure can help to accelerate the healing of epithelium and the improvement of visual acuity early after surgery for advanced keratoconus, compared with vacuum trephine-assisted DALK.
