PURPOSE To demonstrate a novel surgical technique utilising intra-operative optical coherence tomography (iOCT) to aid implantation and optimal placement of two trabecular bypass minimally invasive glaucoma surgery (MIGS) devices - the iStent Inject W and the Hydrus Microstent. METHODS Report on surgical technique with Video accompaniment. RESULTS In iStent Inject W implantation, where the depth of stent implantation has been correlated to post-operative outcomes. the iOCT allows real-time appreciation of device implantation depth relative to the trabecular meshwork surface. In Hydrus Microstent implantation, the iOCT allows confirmation of successful stent placement within the Schlemm's canal, particularly in cases where intra-operative gonioscopic view of the three microstent windows is impeded. CONCLUSION The iOCT is a feasible and useful imaging adjunct to ensure optimal placement of trabecular bypass MIGS devices such as the iStent inject W and Hydrus Microstent.
