An artificial eye model which novice doctors can train a glaucoma surgery has not been enough developed yet. A realistic simulation system for medical education is required. However, although we have been got a sensory evaluation with several eyeball models by experienced doctors, material measurement of only an elastic modulus was lacked to understand the relationship between design of the eyeball model and doctor’s feelings. Therefore, to develop a bionic eyeball for glaucoma surgery practice, it is necessary to extract some mechanical characteristics during incising a sclera with a knife. In this study, we aim to clarify the characteristics through a simplified incision test with an artificial sclera equipped with a layered structure. As the result, we were able to quantify the doctor’s feeling by measuring the reaction force when incising sclera with different fiber diameters in the model.
