Bleb geometry and morphology after Preserflo Microshunt surgery: Risk factors for surgical failure.
PurposeTo investigate the possible risk factors for treatment failure in patients who had undergone Preserflo Microshunt (PMS) implantation, using anterior-segment optical coherence tomography (AS-OCT) to analyze the internal structures of the bleb.MethodsThe PMS blebs of 54 patients were 9002nc evaluated with AS-OCT.A mathematical model was used t
