The paper presents the results of the analysis of general ophthalmic examination, computer keratotopogra-phy and optical coherence tomography of the anterior eye as well as the results of analysis of elastotonometry by Filatov-Kalfa and analysis of the biomechanical strength of the cornea in 96 patients (188 eyes). On the basis of the characteristics complex obtained with the help of modern diagnostic equipment, there was developed a system of assessment of the severity of disturbances of the optical and biomechanical properties of the eyes with keratoconus, taking into account the initial data of the cornea. By means of cluster analysis there were identified three classes of severity: grade 1 — mild, grade 2 — moderate and the third class — a severe degree. A discriminate analysis method was developed a mathematical algorhythm which allowed to determine the severity of keratoconus in each patient by a complex of symptoms.
