Purpose Assessment of topographic and tensor topographic maps of the patients and the analysis of their compliance with deposits Fleischer. Methods 28 patients with disorders of the biomechanics of cornea after RK, PRK, TKC, LASIK, IOL implantation, as well as using the orto‐contact lenses and degenerative changes various stages of keratoconus. All patients complemented by photos recording Fleischer corneatopography deposits and then calculating stress distribution map of the cornea –keratotenzotopogramm (KTT). Results The correlation position Fleischer deposits with zones of maximum mechanical stress gradient in corneas with disabilities form as a result of various causes. Most obviously there Fleischer pigment deposits in the form of rings – after hyperopic LASIK. Position of Fleischer ring correlated with the area of corneal mechanical stress maximum gradient according keratotenzotopogramm Conclusions We are inclined to the hypothesis that Fleischer deposits are natural markers of corneal zone, which are activated in the past or have been active processes caused by excessive mechanical stress in the cornea's stroma.
