application of the model shows that the effective coefficient of scleral rigidity is low ( mean k , 0.0021 ) in eyes with elevated iop that have undergone vitrectomy and retinal cryopexy and very low ( mean k , 0.0013 ) in eyes with elevated iop that have undergone placement of a scleral buckle and band .
