For people with chronic closed-angle glaucoma, lens extraction can relieve the block created by the pupil and help regulate the intraocular pressure.<ref>{{cite journal | vauthors = Ong AY, Ng SM, Vedula SS, Friedman DS | title = Lens extraction for chronic angle-closure glaucoma | journal = The Cochrane Database of Systematic Reviews | volume = 2021 | issue = 3 | pages = CD005555 | date = March 2021 | pmid = 33759192 | pmc = 8094223 | doi = 10.1002/14651858.CD005555.pub3 }}</ref> A study found that CLE is even more effective than laser peripheral [[iridotomy]] in patients with angle closure glaucoma.<ref>{{Cite journal |last1=Tanner |first1=Luke |last2=Gazzard |first2=Gus |last3=Nolan |first3=Winifred P. |last4=Foster |first4=Paul J. |date=January 2020 |title=Has the EAGLE landed for the use of clear lens extraction in angle-closure glaucoma?
