PURPOSE: To compare the performance of the double-mirror goniolens with dual viewing system in goniosurgery, goniosynechialysis, and trabeculotomy ab externo with that of the conventional Swan-Jacob gonioprism (SJG). DESIGN: Prospective interventional case series. METHODS: We treated 10 patients (10 eyes) with medically uncontrollable chronic angle-closure glaucoma by goniosynechialysis and another 10 eyes with open-angle glaucoma by trabeculotomy ab externo (TLO). The 20 patients were divided randomly into two equal groups and underwent operation with the double-mirror goniolens or SJG instrument. RESULTS: There were no intraoperative complications, irrespective of the procedure or instrument that was used. Patients in the SJG group were required to tilt the head at a > 30-degree angle to facilitate observation and manipulation of the quadrants. On the other hand, all structures could be observed and manipulated without head-tilting in the double-mirror goniolens group. CONCLUSION: The double-mirror goniolens with dual viewing system is more suitable than the conventional SJG for goniosurgery.
