| Outflow pipe implant with check valve is a new glaucoma ocular tension treatment, developed primarily to correct the deteriorated intraocular fluid circulation in glaucoma disease. The research focus is to analyze a new outflow pipe implant with check valve material behavior for improving intraocular fluid outflow structure. Very few computational studies have considered both the mechanical and fluid flow impact of outflow pipe implant with check valve. There is non-available literature on outflow pipe implant with check valve structure and appropriate material selection to release the aqueous humor in intraocular stabilized pressure. The CFD-ANSYS simulation model was investigated for realization of realistic fluid flow velocity and pressure of aqueous humor behavior in microenvironment of the suprachoroidal space. The static structure and the von Mises stress for failure mode were studied to explore geometrical shape and material deformation structure by finite element method in ANSYS. Research results show affirmatively that structural analysis data correlates with fluid dynamics data in agreement. |
