Abstract
Definition of the force and torque boundaries during ophthalmic operations is a vital step towards design and development of robotic solutions for eye surgery. This paper describes the development of an eyeball FEA model. Unlike other eyeball FEA studies, this 3D eyeball model contains all three layers of the inner eye: retina, choroid and sclera. Furthermore the model includes six extra ocular muscles. The intraocular rotation of a needle tool using a trocar during the surgery was also considered in this study. Although variables such as the thickness of the layers and the property of the orbits and the muscles are unique for every individual, the model was developed by introducing some assumptions and constraints for an average eye. However by changing few parameters a modified model suitable for individuals can be generated. The model gives the stress distribution when the needle rotates inside the eyeball. The results of this study will give a numerical understanding of the forces which are needed for ophthalmic operation.
