Comparing the Effectiveness of Propensity Score-Matched Ab Interno Trabeculotomy Between Two Types of Trabecular Hooks

Surgical outcomes for ab interno trabeculotomy using the KDB and TMH were not significantly different. There was no significant difference in the occurrence of postoperative complications, except hyphema, which may reflect the difference in the incision range of trabeculotomy between the hooks. Finally, in the KDB group, where narrow incisions range up to just over one quadrant, the trabeculotomy incision range correlated with IOP.
