ABSTRACT
Up-to-date models of intrastromal corneal segments are reviewed. Different techniques of up-to-date models of intrastromal corneal segments implantation in keratoconus are described. Mechanical and laser techniques of forming of corneal tunnels are analyzed. Information about potential complications of intrastromal corneal segment implantation is given.

Comparative analysis of intrastromal corneal segments Keraring implantation using either femtosecond laser or manual technique to create corneal tunnel in 47 patients (47 eyes) with keratoconus stage II-III is presented. Refractional and functional results in groups with femtosecond laser and manual technique did not show significant difference. The main advantage of femtosecond laser revealed in the study is technical simplification of intrastromal tunnels creation.
