Drops fail patients in predictable ways: adherence, cost, and the ocular surface. That's why glaucoma is moving toward earlier intervention. I'll cover angle anatomy, then the toolkit (trabecular micro-bypass stents, canal scaffolds, goniotomy, canaloplasty, ECP, and sustained-release implants) with honest outcomes for each. You'll leave knowing who to select, who to avoid, what to expect post-op, and how to manage drops and monitor progression afterward.
