This retrospective comparative case series examined 52 \u03bcLOT-Phaco eyes that underwent surgery between September 2017 and December 2020. Surgical qualified success was defined as an intraocular pressure (IOP) of \u226420 mmHg, \u226520% IOP reduction with IOP-lowering medications, and no additional glaucoma surgery. Success rates were evaluated by Kaplan-Meier survival analysis. The number of postoperative IOP-lowering medications and occurrence of complications were also assessed. Mean preoperative IOP in the 120\u00b0 group was 16.9 \u00b1 7.6 mmHg, which significantly decreased to 10.9 \u00b1 2.7 mmHg (p &lt; 0.01) and 11.1 \u00b1 3.1 mmHg (p = 0.01) at 12 and 24 months, respectively. The mean number of preoperative IOP-lowering medications significantly decreased from 2.8 \u00b1 1.4 to 1.4 \u00b1 1.4 (p &lt; 0.01) at 24 months. Mean preoperative IOP in the 180\u00b0 group was 17.1 \u00b1 7.0 mmHg, which significantly decreased to 12.1 \u00b1 3.2 mmHg (p = 0.02) and 12.9 \u00b1 1.4 mmHg (p = 0.01) at 12 and 24 months, respectively. The mean number of preoperative IOP-lowering medications significantly decreased from 2.9 \u00b1 1.2 to 1.4 \u00b1 1.5 (p &lt; 0.01) at 24 months. The probability of qualified success at 24 months in the 120\u00b0 and 180\u00b0 groups was 50.4% and 54.6%, respectively (p = 0.58). There was no difference observed for hyphema formation or IOP spikes. Surgical outcomes were not significantly different between the 120\u00b0 and 180\u00b0 incisions in Schlemm\u2019s canal.<\/jats:p>","DOI":"10.3390\/jcm10143181","type":"journal-article","created":{"date-parts":[[2021,7,19]],"date-time":"2021-07-19T10:07:37Z","timestamp":1626689257000},"page":"3181","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Comparison of Efficacy between 120\u00b0 and 180\u00b0 Schlemm\u2019s Canal Incision Microhook Ab Interno Trabeculotomy"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0331-4104","authenticated-orcid":false,"given":"Naoki","family":"Okada","sequence":"first","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuyuki","family":"Hirooka","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiromitsu","family":"Onoe","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yumiko","family":"Murakami","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0943-2219","authenticated-orcid":false,"given":"Hideaki","family":"Okumichi","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiaki","family":"Kiuchi","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Hiroshima University, Hiroshima 734-8551, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"262","DOI":"10.1136\/bjo.2005.081224","article-title":"The number of people with glaucoma worldwide in 2010 and 2020","volume":"90","author":"Quigley","year":"2006","journal-title":"Br.
