[Intrastromal corneal segments implantation in keratoconus]

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.
