Autologous h-ADSCs corneal stroma implantation for advanced keratoconus. (A) Slit lamp picture 24 h after the procedure; (B) Topographic changes (Pentacam) between preop and 6 months after surgery. Observe the overall stability of the keratometric parameters; (C) Corneal confocal biomicroscopy pictures at the surgical plane in the first postoperative month. Stem cell survival is confirmed by the presence of cells showing a more rounded morphology (white arrows) (image corresponds to an area of 0.1 mm2); (D) AS-OCT picture 6 months postoperatively. Note the patched hyper-reflective areas (red arrows) at the level of the stromal pocket compatible with areas of new collagen production.
