Abstract
Relevance. Keratoconus is a common asymmetric and usually bilateral ectatic corneal disease characterized by progressive corneal protrusion, resulting in reduced visual acuity and deterioration of optical properties. Purpose of the study. To evaluate the effectiveness of surgical treatment of keratoconus with various combined methods. Material and methods. The article presents a comparative analysis of data from patients with II and III stages of keratoconus (52 patients, 66 eyes) after implantation of intrastromal corneal ring segments with femtosecond accompaniment, followed by corneal crosslinking and corneal crosslinking, followed by implantation of intrastromal corneal ring segments with femtosecond accompaniment. Results and conclusion. The refractive result for the spherical and cylindrical components gave the best result in group 2, in which stage 1 was implantation of ICRS, and stage 2 was corneal collagen crosslinking, compared with group 1, in which stage 1 was corneal collagen crosslinking, and stage 2 was implanted ICRS. Progression stopped in 65 cases. Keywords: keratoconus, intrastromal corneal segments, femtosecond laser, corneal crosslinking.
