Purpose: To investigate clinical safety of a novel liquid interface technology for femtosecond laser assisted perforating keratoplasty, maintaining the corneal curvature without the necessity of applanation of the cornea.
Methods: Six patients received a femtosecond laser keratoplasty with a new liquid interface providing a non-applanating trephination. Clinical outcome was evaluated 1 and 3 months after surgery.
Results: All procedures were performed without complications and donor and recipient corneas could be aligned without problems, even in cases of advanced keratoconus. Although this initial pilot study investigated clinical safety, a positive effect on postoperative astigmatism was observed.
Conclusion: We could show in this pilot study, that a hand-held liquid patient interface in combination with a femtosecond laser is safe to use in penetrating keratoplasty, aiming an improved postoperative astigmatism.
