Analysis of keratopographic and biomechanical corneal indicators with evaluation of the impact of diagnostic results on myopic refraction patient management tactics D.D. Sibakin, V.A. Breev, E.G. Solodkova S. Fyodorov Eye Microsurgery Federal State Institution, Volgograd Branch, Volgograd, Russian Federation Purpose. To analyse keratopographic and biomechanical corneal indicators with the diagnostic results assessment of the influence on the treatment tactics of myopic refraction patient. Material and methods. Keratotopographic and biomechanical parameters of the cornea in a patient with mild myopia were evaluated. Results. The Belin/Ambrosio (Enchanced Ectasia Display) – BAD keratoconus screening program was used on Pentacam AXL, which did not reveal corneal pathology. According to the results of CBI (Corvis biomechanical index) on Corvis ST (Oculus, Germany) (OD – 0.61, OS – 0.48), that was indicating poor corneal biomechanical properties and a high risk of keratectasia development. Conclusion. Ophthalmic examination, using The Corvis ST biomechanical measurements, makes possible to reveal with greater sensitivity subclinical signs of a keratectatic process at the pre-clinical stage of development.
