Determination of the hyperelastic material behavior of hydrogel specimens for expandable lens implants

Abstract

Theoretical and experimental investigations were carried out for development of human lens implants made from hydrogel material. The material properties were measured and implemented in a Finite element model. Though the material is still too stiff for accommodative lenses, the theoretical and experimental foundations for the implant development were established.
