'''Excimer laser trabeculostomy''' (ELT) is a procedure to create holes in the [[trabecular meshwork]] to reduce [[intraocular pressure]]. It uses a [[xenon monochloride|XeCl]] 308&nbsp;nm [[excimer laser]].<ref name=":0">{{Cite web |date=19 December 2013 |title=Excimer Laser Trabeculostomy: An Effective Microinvasive Glaucoma Surgery Procedure for Open-Angle Glaucoma - American Academy of Ophthalmology |url=https://www.aao.org/education/munnerlyn-laser-surgery-center/excimer-laser-trabeculostomy-effective-microinvasi |access-date=2023-12-04 |website=www.aao.org}}</ref> It is considered a [[minimally invasive glaucoma surgery|minimally invasive glaucoma surgeries]], and was first described in 1987 by Michael Berlin.<ref>{{cite journal| vauthors = Berlin MS, Toeteberg-Harms M, Kim E, Vuong I, Giers U | title = Excimer Laser Trabeculostomy: An Effective Microinvasive Glaucoma Surgery Procedure for Open-Angle Glaucoma. | journal = Current Insight | date = December 2013 | page = 19 | publisher = American Academy of Ophthalmology | url=https://www.aao.org/munnerlyn-laser-surgery-center/excimer-laser-trabeculostomy-effective-microinvasi }}</ref>
Alternative treatments for glaucoma include mechanical drilling, thermal lasers, thermal cauterisation, and tube implants. However, these approaches typically disrupt the eye tissue enough to cause [[inflammation]] which often outweighs the benefit of the procedure.<ref name=":0" /> Excimer laser trabeculostomy uses [[Low-level laser therapy|cold lasers]] which reduces tissue [[fibrosis]] otherwise caused by excimer lasers. A 2020 review of 8 studies found the procedure reduced intraocular pressure by 20-40% and generally had favourable outcomes for reducing glaucoma medication needs.<ref>{{cite journal | vauthors = Durr GM, Töteberg-Harms M, Lewis R, Fea A, Marolo P, Ahmed II | title = Current review of Excimer laser Trabeculostomy | journal = Eye and Vision | volume = 7 | issue = 1 | pages = 24 | date = 2020-05-05 | pmid = 32391398 | pmc = 7199329 | doi = 10.1186/s40662-020-00190-7 | doi-access = free }}</ref>
