Objectives: This study evaluated the clinical preferences of glaucoma specialists regarding glaucoma surgery and postoperative management in Japan in 2024. Methods: A survey about clinical practice preferences regarding glaucoma surgery and postoperative care was administered among 50 glaucoma specialists who were councilors in the Japan Glaucoma Society. Results: Minimally invasive glaucoma surgery (MIGS) plus phacoemulsification was the most preferred procedure for nonoperated mild to moderate cases of primary open-angle glaucoma (POAG) (94.6%) and normal tension glaucoma (NTG) (67.3%) associated with cataract. Microhook surgery was the most preferred among the MIGS procedures. Meanwhile, PreserFlo MicroShunt (PMS) surgery is emerging as a popular option for cases of POAG and NTG, especially in advanced-stage pseudophakic eyes that underwent prior corneal incision phacoemulsification (40.1%). Long-tube shunt surgeries were predominantly preferred for POAG after two failed trabeculectomies (69.4%) and for neovascular glaucoma with prior vitrectomy after a failed trabeculectomy (73.0%). Among long-tube shunt surgeries, the Ahmed glaucoma valve (AGV) was preferred over the Baerveldt glaucoma implant. Trabeculectomy required the most frequent follow-up visits within the first postoperative year, whereas PMS and long-tube shunt surgeries required comparatively fewer follow-up visits. Overall, MIGS involved less frequent follow-up visits versus filtering surgeries. Conclusions: MIGS is currently the procedure of choice for primary glaucoma surgery in Japan. Among glaucoma specialists of the Japan Glaucoma Society, PMS surgery is becoming popular for cases of POAG and NTG. Refractory glaucoma is commonly treated with long-tube shunt surgeries, especially the AGV.
