Microhook ab interno trabeculotomy, a novel minimally invasive glaucoma surgery

Masaki Tanito Division of Ophthalmology, Matsue Red Cross Hospital, Matsue, Japan Abstract: Trabeculotomy (LOT) is performed to reduce the intraocular pressure in patients with glaucoma, both in children and adults. It relieves the resistance to aqueous flow by cleaving the trabecular meshwork and...
