Is there a predisposition for developing corneal hydrops in keratoconus?—Tomographic and biomechanical analysis of the fellow eyes

ACH-FE showed a predominant presence in stage B4, yet a heterogenic distribution in the other tomographic parameters ('A'|'C'). Lower SP-A1 values suggest that these eyes may be less stiff and resistant to mechanical stress. Our results potentially indicate a histopathological weakness in the posterior cornea that could predispose one to the development of ACH.
