Computational modelling of theoretical posterior segment ring implants as a potential glaucoma therapy. A) Generic human eye model geometry and FE mesh. B) Proposed intrascleral (IS) ring implant (implant material stiffness = 200GPa). C) Alternative ring implant (200GPa stiffness) located in the subarachnoid space (SAS). D) Effect of SAS and IS+SAS combination implants on calculated ONH deformation behaviour, under a simulated IOP of 50mmHg. A maximum 66% reduction in scleral canal expansion and a 28% reduction in LC strain are predicted by the model under the double ring combination implant strategy.
