The Use of Femtosecond Laser and Corneal Welding in the Surgery of Keratoconus

The laser-assisted lamellar and penetrating keratoplasty, supported by the use of laser welding procedure, is particularly suitable for keratoconus patients. Laser welding approach is based on the use of a near infrared laser that induces a photothermal effect mediated by a biocompatible chromophore (Indocyanine Green). The main characteristic is to provide an immediate closure of the surgical wound, a fast healing process, and a stable biomechanical result. These effects in the postoperative period are of particular importance in young patients, i.e., in keratoconus patients, providing them the possibility to perform sports and any working activities.
