Abstract There is an unmet need in the glaucoma clinic to control changes in the intraocular pressure (IOP), i.e., patient-specific hypotony and tissue fibrosis-mediated ocular hypertension, owing to the fixed tube diameter of the glaucoma drainage device. As a potential solution, the tube diameter can be adjusted, depending on the IOP, by shape memory polymer (SMP) and clinical laser systems, which can control the energy level, focus, and frequency by minimizing untargeted influences.
