This effect seems to be more noticeable in eyes with narrow angles (NAs) than in eyes with open angles (OAs). Decrease in IOP may be a result of the increase in anterior chamber angle and Schlemm canal (SC) after cataract surgery. The purpose of this paper was to evaluate the relationship between Schlemm canal-cross-sectional area (SC-CSA) changes and trabecular meshwork, ciliary muscle changes after cataract surgery and the difference in non-glaucomatous eyes with NAs and OAs. Methods: IOP, SC-CSA, Schlemm canal diameter (SCD), trabecular meshwork width (TMW) and thickness (TMT), trabecular-iris angle at 500 \u00b5m from the scleral spur (TIA500), and the distance between the inner apex of the ciliary muscle and scleral spur (IA-SS) were measured by swept-source-optical coherence tomography preoperatively and 1-week post-surgery. Patients were divided into NA and OA groups according to the degree of TIA500, and SC-CSA-related parameters were compared. Results: Seventy-five patients (89 eyes) were included. IOP significantly decreased, SC-CSA, SCD, TMW, TMT, and TIA500 significantly increased post-surgery (p &lt; 0.001). Changes in nasal SC-CSA were associated with TMW (p = 0.003) and TIA500 (p &lt; 0.001) changes; changes in temporal SC-CSA were associated with TMW (p = 0.001) and TMT (p &lt; 0.001) changes. SC-CSA expansion was correlated with changes in TMW (\u03b23.726 \u00b1 1.085, p = 0.001 nasally; \u03b23.405 \u00b1 0.945, p = 0.001 temporally), TMT (\u03b25.224 \u00b1 2.033, p = 0.012 nasally; \u03b211.853 \u00b1 3.059, p &lt; 0.001 temporally), and TIA500 (\u03b240.330 \u00b1 15.100, p = 0.009 nasally; \u03b235.453 \u00b1 17.527, p = 0.047 temporally). There was no association between SC-CSA expansion and IA-SS changes. SC-CSA expansion was greater in the NAs than in the OAs group (p &lt; 0.001). Conclusion: Cataract surgery results in IOP reduction and SC-CSA expansion. Increased SC-CSA correlates with increases in TMW, TMT, and TIA500. SC-CSA increased more in NAs than in OAs group post-surgery, which may explain the greater decrease in IOP in eyes with NAs. <\/jats:p>","DOI":"10.1159\/000543303","type":"journal-article","created":{"date-parts":[[2025,1,21]],"date-time":"2025-01-21T17:01:05Z","timestamp":1737478865000},"page":"100-107","source":"Crossref","is-referenced-by-count":2,"title":["The Change of Ciliary Muscle-Trabecular Meshwork-Schlemm Canal Complex after Phacoemulsification using Swept-Source-Optical Coherence Tomography"],"prefix":"10.1159","volume":"68","author":[{"given":"Zhangliang","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueer","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinpei","family":"Ji","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zehui","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nan","family":"Zhe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4401-8053","authenticated-orcid":false,"given":"Yun-e","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2025,1,21]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-9071.2012.02871.x"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2011.06.037"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.16-20583"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1001\/archophthalmol.2011.272"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2003.08.023"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2007.04.009"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2008.05.049"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-015-3135-7"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097\/IJG.0b013e3181650f31"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1097\/01.ijg.0000131757.63542.24"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.preteyeres.2020.100917"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1117\/1.JBO.19.10.106013"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.15-17091"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.13-13699"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.62.5.302"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1006\/exer.1996.0012"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1111\/opo.12451"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0145824"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2020.02.005"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1981.03930010106013"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2009.05.061"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2007.12.045"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.13-13700"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1001\/jamaophthalmol.2016.1881"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2021.763736"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1016\/s0886-3350(01)01036-7"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1038\/eye.2015.141"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2013.02.003"}],"container-title":["Ophthalmic Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/ore\/article-pdf\/68\/1\/100\/4326113\/000543303.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/ore\/article-pdf\/68\/1\/100\/4326113\/000543303.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:07:50Z","timestamp":1745420870000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000543303"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,1,21]]},"references-count":28,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025,1,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000543303","archive":["Portico"],"relation":{},"ISSN":["0030-3747","1423-0259"],"issn-type":[{"value":"0030-3747","type":"print"},{"value":"1423-0259","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1,21]]}}}
