Methods: An observational, prospective study was performed on 66 patients who had cataract surgery including 22 chronic PACG patients, 22 acute PACG patients, and 22 open-angle cataract patients. Anterior segment parameters including the trabecular-ciliary process distance, ciliary process area, trabecular-ciliary angle (TCA), maximum ciliary body thickness (CBTmax), and so on, were measured using ultrasound biomicroscopy preoperatively and 3 months postoperatively. Results: After the surgery, there were significant increases in TCA (p &lt; 0.001) and CBTmax (p &lt; 0.05) in all three groups, while there was no significant change in the trabecular-ciliary process distance (p &gt; 0.05) in all three groups. No significant difference in the changes of ciliary process area, TCA, and CBTmax (p &gt; 0.05) pre- and postoperatively among the three groups were identified. Conclusions: Extractions of crystalline lenses played similar roles in terms of decreasing the anterior rotation of ciliary processes in open-angle eyes and angle-closure eyes. A natural anatomical abnormality may be a more important factor in the anterior rotation of ciliary processes in PACG patients.<\/jats:p>","DOI":"10.3390\/jcm12010327","type":"journal-article","created":{"date-parts":[[2023,1,2]],"date-time":"2023-01-02T03:00:59Z","timestamp":1672628459000},"page":"327","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Anterior Segment Parameter Changes after Cataract Surgery in Open-Angle and Angle-Closure Eyes: A Prospective Study"],"prefix":"10.3390","volume":"12","author":[{"given":"Kangyi","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Peking University People\u2019s Hospital, Beijing 100044, China"},{"name":"Eye Diseases and Optometry Institute, Beijing 100044, China"},{"name":"Beijing Key Laboratory of Diagnosis and Therapy of Retinal and Choroid Diseases, Beijing 100044, China"},{"name":"College of Optometry, Peking University Health Science Center, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiqiao","family":"Liang","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Peking University People\u2019s Hospital, Beijing 100044, China"},{"name":"Eye Diseases and Optometry Institute, Beijing 100044, China"},{"name":"Beijing Key Laboratory of Diagnosis and Therapy of Retinal and Choroid Diseases, Beijing 100044, China"},{"name":"College of Optometry, Peking University Health Science Center, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Lv","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Peking University People\u2019s Hospital, Beijing 100044, China"},{"name":"Eye Diseases and Optometry Institute, Beijing 100044, China"},{"name":"Beijing Key Laboratory of Diagnosis and Therapy of Retinal and Choroid Diseases, Beijing 100044, China"},{"name":"College of Optometry, Peking University Health Science Center, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yao","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Peking University People\u2019s Hospital, Beijing 100044, China"},{"name":"Eye Diseases and Optometry Institute, Beijing 100044, China"},{"name":"Beijing Key Laboratory of Diagnosis and Therapy of Retinal and Choroid Diseases, Beijing 100044, China"},{"name":"College of Optometry, Peking University Health Science Center, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianru","family":"Hou","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Peking University People\u2019s Hospital, Beijing 100044, China"},{"name":"Eye Diseases and Optometry Institute, Beijing 100044, China"},{"name":"Beijing Key Laboratory of Diagnosis and Therapy of Retinal and Choroid Diseases, Beijing 100044, China"},{"name":"College of Optometry, Peking University Health Science Center, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3349-986X","authenticated-orcid":false,"given":"Huijuan","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Peking University People\u2019s Hospital, Beijing 100044, China"},{"name":"Eye Diseases and Optometry Institute, Beijing 100044, China"},{"name":"Beijing Key Laboratory of Diagnosis and Therapy of Retinal and Choroid Diseases, Beijing 100044, China"},{"name":"College of Optometry, Peking University Health Science Center, Beijing 100044, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"273","DOI":"10.1016\/j.ajo.2019.08.004","article-title":"Deep Learning Classifiers for Automated Detection of Gonioscopic Angle Closure Based on Anterior Segment OCT Images","volume":"208","author":"Xu","year":"2019","journal-title":"Am.
