小梁切开术（LOT）用于降低儿童和成人青光眼患者的眼压。它通过劈开小梁网和施勒姆管内壁来减轻对水流动的阻力。Microhook ab interno LOT （mu LOT）是一种新型的微创青光眼手术，通过角膜侧孔插入小钩子切开小梁网。一项初步的病例系列报道表明，在日本青光眼患者术后早期，单独使用mu LOT或联合使用mu LOT和白内障手术可使眼压恢复正常。与常规直刀相比，微钩刀能在不损伤外壁的情况下切开施莱姆管内壁。mu LOT的优点包括：LOT的范围更大（周长的三分之二），手术技术更简单，对眼表的侵入性更小，手术时间比传统的体外LOT短，不需要昂贵的设备。本文介绍了mu LOT的手术技术及注意事项。
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 (mu LOT), 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 mu LOT alone and combination of mu LOT 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 mu LOT 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 mu LOT and tips of the technique are introduced.
