Keratoconus treatment using femtosecond-assisted intrastromal corneal graft (FAISCG) surgery: a case series.

We describe an intrastromal corneal graft technique that uses femtosecond laser to create a desirable corneal lenticule with precise diameter, depth, and shape as well as an intra-stromal pocket in keratoconus patients. The technique seems to be a feasible and safe treatment option to treat keratoconic eyes with reference to the irregularity and instability of cornea. The technique can be performed easily and appears safe and effective. At 7 days postoperatively, all eyes were white and quiet, and the grafts were clear. No graft folds or interface complications were observed at the 12-month follow-up using Visante optical coherence tomography.
