Fig. 2From: New dawn for keratoconus treatment: potential strategies for corneal stromal regenerationMinimally invasive surgical methods and bioengineered grafts for keratoconus treatment. An intrastromal pocket with a small incision were created by femtosecond laser, the human stromal button (a) or bioengineered BPCDX graft (b) were gently inserted into the intrastromal pocket to increase the corneal thickness.
