Predictability of Tunnel Depth for Intrastromal Corneal Ring Segments Implantation Between Manual and Femtosecond Laser Techniques

Intrastromal corneal ring segments (ICRS) implantation is a surgical procedure used for the treatment of keratoconus, enabling both a therapeutic and refractive improvement.1 –3 Both the safety and the refractive efficacy of the implant depend on the correct selection of the implant features and a precise intrastromal surgical implantation. Shallower intrastromal tunnels are associated with complications such as implant exposure due to corneal thinning over the implant , segment migration and extrusion, astigmatism overcorrection, or corneal melting.4–6 Deeper tunnels can be associated with
