Features of using optimization algorithms for personalizing the geometric and biomechanical parameters of the cornea model [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаThis study explores the personalization of a 3D finite element model of the cornea for diagnosing its biomechanical properties in keratoconus and predicting treatment outcomes. A key limitation of existing models is their reliance on averaged parameters,
