Buckling operation is frequently performed in clinic to treat the eyeball retinal detachment. However, the effect of operation heavily depends on the surgical experiences at present. In this paper, to numerically simulate this operation in order to predict the suitable conditions for clinical operation, a 2-D FEM program for coupling analysis of hyperelastic solid and static liquid is developed based on an incompressible hyperelastic program which was developed by authors for analysis of the soft tissues of livinghuman, and its effectiveness is demonstrated by a testing analysis. It is further applied to the simulation of the segmental buckling operation on an eyeball to qualitatively investigate the influence of the buckle shape, suture width and eyeball internal pressure on the operation. By this simulation, the useful results are obtained and it is expected that proper buckle effect will be available in clinical operation with the aid of these results.
