Methods: This retrospective cohort study included 109 and 229 eyes that underwent BGI surgery and trabeculectomy, respectively, at Fukui University Hospital. Corneal astigmatism was assessed preoperatively, and at 6 months postoperatively, the mean SIA (M-SIA) and centroid SIA were calculated, and factors associated with M-SIA were determined. Results: BGI surgery was associated with greater SIA than trabeculectomy. Postoperative corneal astigmatism was \u22121.53 \u00b1 1.01 D in the BGI group and \u22121.33 \u00b1 0.92 D in the trabeculectomy group (p = 0.044). The M-SIA was significantly larger in the BGI group (1.41 \u00b1 1.05 D vs. 0.94 \u00b1 0.74 D, p &lt; 0.01). Multivariate regression revealed that BGI surgery and lower preoperative corneal astigmatism were independently associated with greater M-SIA. Subgroup analysis revealed that older age and lower preoperative astigmatism were significant predictors of larger M-SIA in the BGI group, whereas only preoperative astigmatism was significant in the trabeculectomy group. Conclusions: BGI surgery was associated with greater and more variable SIA than trabeculectomy. Surgical type, baseline astigmatism, and age are important predictors of postoperative SIA.<\/jats:p>","DOI":"10.3390\/jcm15041620","type":"journal-article","created":{"date-parts":[[2026,2,20]],"date-time":"2026-02-20T08:50:03Z","timestamp":1771577403000},"page":"1620","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of Surgically Induced Astigmatism Between Baerveldt Glaucoma Implant Surgery and Trabeculectomy: A Retrospective Cohort Study"],"prefix":"10.3390","volume":"15","author":[{"given":"Kengo","family":"Tanaka","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medical Sciences, University of Fukui, Fukui 910-1193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kentaro","family":"Iwasaki","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medical Sciences, University of Fukui, Fukui 910-1193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5660-3260","authenticated-orcid":false,"given":"Shogo","family":"Arimura","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medical Sciences, University of Fukui, Fukui 910-1193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medical Sciences, University of Fukui, Fukui 910-1193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7334-2245","authenticated-orcid":false,"given":"Yoshihiro","family":"Takamura","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medical Sciences, University of Fukui, Fukui 910-1193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaru","family":"Inatani","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medical Sciences, University of Fukui, Fukui 910-1193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,20]]},"reference":[{"key":"ref_1","first-page":"395","article-title":"The effect of trabeculectomy on corneal topography","volume":"23","author":"Rosen","year":"1992","journal-title":"Ophthalmic Surg."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"292","DOI":"10.1038\/eye.1995.57","article-title":"The effect of trabeculectomy on refraction, keratometry and corneal topography","volume":"9","author":"Claridge","year":"1995","journal-title":"Eye"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1097\/00061198-199704000-00005","article-title":"Visual function following trabeculectomy: Effect on corneal topography and contrast sensitivity","volume":"6","author":"Dietze","year":"1997","journal-title":"J.
