From: Keratectasia severity staging and progression assessment based on the biomechanical E-staging
Representative course of the “Homburg Biomechanical E-Staging” after implantation of intracorneal ring segments as displayed by the Corvis ST® (Oculus, Wetzlar, Germany). Female, 39-year-old patient with keratoconus and follow-up examinations from 2019 to 2020. Red, baseline examination (Oct 04, 2019). Implantation of Intacs® SK intracorneal ring segments was performed (Nov 28, 2019). Green, first follow-up with slightly higher biomechanical E-staging about four months later (Mar 13, 2020). Yellow, second follow-up with markedly higher biomechanical E-staging (May 29, 2020). Blue, third follow-up (Sep 11, 2020) with decreasing biomechanical E-staging comparable to baseline about ten months after intracorneal ring segment implantation
