Mechanical eye model for evaluation of intraocular pressure measuring under consideration of the biomechanical characteristics

A mechanical eye model has been developed which offers the possibility to set up, carry out and to evaluate intraocular pressure (IOP) measurements under consideration of different biomechanical characteristics. These characteristics are realized by designing model components with various geometries and material properties. Two different cornea thicknesses have been investigated, simulating different inner pressures via a controlled mechanical system, consisting of eyeball-like fluid-filled chamber whose pressure could be altered and measured. Results show significant characteristics in the signals recorded via test sensor as tonometry system, which are in line with medical predications. Using this model the evaluation of tonometry systems under considerations of biomechanical characteristics and environmental conditions can be done.
