description 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 the inner walls of Schlemm’s canal. Microhook ab interno LOT (µLOT), a novel minimally invasive glaucoma surgery, incises trabecular meshwork using small hooks that are inserted through corneal side ports. An initial case series reported that both µLOT alone and combination of µLOT and cataract surgery normalize the intraocular pressure during the early postoperative period in Japanese patients with glaucoma. Microhook can incise the inner wall of Schlemm’s canal without damaging its outer wall easier than the regular straight knife that is used during goniotomy. Advantages of µLOT include: a wider extent of LOT (two-thirds of the circumference), a simpler surgical technique, being less invasiveness to the ocular surface, a shorter surgical time than traditional ab externo LOT, and no requirement for expensive devices. In this paper, the surgical technique of µLOT and tips of the technique are introduced. Keywords: trabecular meshwork, Schlemm’s canal, intraocular pressure, surgical procedure, glaucoma
