Complications of Intra Corneal Ring Segment Implantation with Femtosecond Laser Channel Creation in patients with Keratoconus (Explanations and Solutions)

The present study analyzes the complications of intracorneal ring segment implantation using a femtosecond laser for channel creation in patients with keratoconus. This technique, as in all surgical procedures, a risk of complications is always present and must be addressed appropriately to ensure that optimal results are achieved with the least possible incidence of adverse effects. We fully discussed possible intraand post-operative complications of this surgery and how to manage them. Complications such as endotelial perforation, incorrect entry of the cannel, galvanometer lag error, abnormality-shaped channel creation, vacuum loss, segment migration, decentration, axis incision, corneal melting, neovascularization and infection are described and discussed.
