This retrospective case series included 40 eyes that underwent \u00b5LOT combined with cataract surgery at Kochi University Hospital. Groups 1 (20 eyes) and 2 (20 eyes) included eyes that underwent \u00b5LOT before and after cataract surgery, respectively. The patient characteristics and clinical outcomes were also analyzed. The mean preoperative intraocular pressure (IOP) in Groups 1 and 2 (26.1 \u00b1 12.2 mmHg and 20.6 \u00b1 8.8 mmHg) was reduced significantly to 14.1 \u00b1 3.3 mmHg and 12.9 \u00b1 3.2 mmHg, respectively, at 5\u20137 months postoperatively. The median preoperative number of antiglaucoma medications in Groups 1 and 2 (4.0 and 3.5) also decreased significantly, to 2.5 and 1.0, respectively, at 5\u20137 months postoperatively. Postoperative hyphema with niveau formation in Groups 1 and 2 was observed in one eye (5.0%) and six eyes (30.0%), respectively. For the combination of \u00b5LOT and cataract surgery, performing \u00b5LOT before cataract surgery may be less likely to result in postoperative hyphema with niveau formation.<\/jats:p>","DOI":"10.3390\/jcm11030738","type":"journal-article","created":{"date-parts":[[2022,1,29]],"date-time":"2022-01-29T23:02:06Z","timestamp":1643497326000},"page":"738","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Comparison of Different Procedures in a Combination of Ab Interno Microhook Trabeculotomy and Cataract Surgery"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0554-9660","authenticated-orcid":false,"given":"Yusaku","family":"Miura","sequence":"first","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Kochi Medical School, Kochi University, Nankoku 783-8505, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4990-6308","authenticated-orcid":false,"given":"Ken","family":"Fukuda","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Kochi Medical School, Kochi University, Nankoku 783-8505, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,29]]},"reference":[{"key":"ref_1","first-page":"735","article-title":"Trabeculotomy ab externo: An alternative treatment in adult patients with primary open-angle glaucoma","volume":"24","author":"Chihara","year":"1993","journal-title":"Ophthalmic Surg."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1653","DOI":"10.1001\/archopht.1993.01090120075025","article-title":"Surgical effects of trabeculotomy ab externo on adult eyes with primary open angle glaucoma and pseudoexfoliation syndrome","volume":"111","author":"Tanihara","year":"1993","journal-title":"Arch.
