Uncorrected visual acuity, manifest refraction, corneal topography, anterior segment optical coherence tomography was performed pre- and six months postoperatively. Total ocular astigmatism, corneal astigmatism, vector of surgically induced corneal astigmatism (SICA), non-corneal ocular residual astigmatism (N-CORA), postoperative intraocular lens decentration and tilt were analyzed. <\/jats:p><\/jats:sec>Results<\/jats:title> Thirty-eight subjects were included: 21, R group; 17, L group. After surgery, the N-CORA decreased significantly from 1.17\u00b10.72 D to 0.73\u00b10.47 D in all patients (P=0.001), 1.03\u00b10.52 D to 0.70\u00b10.40 D in the R group (P=0.005) and 1.35\u00b10.90 D to 0.78\u00b10.55 D in the L group (P=0.033). Significant differences between t:he R and L groups were found in the postoperative meridian of anterior corneal astigmatism (75.95\u00b152.50 vs 116.79\u00b147.29; P=0.017), total corneal astigmatism (51.65\u00b142.75 vs 95.20\u00b157.32; P=0.011), J45 change vector of SICA in the anterior cornea (-0.10\u00b10.18 vs 0.00\u00b10.11; P=0.048) and total cornea surface (-0.14\u00b10.17 vs 0.03\u00b10.12; P=0.001). <\/jats:p><\/jats:sec>Conclusion<\/jats:title> The N-CORA decreased significantly after cataract surgery. Superotemporal and temporal incisions caused differences in the meridian components of oblique astigmatism in some patients but did not have a significant effect on the magnitude of corneal astigmatism. <\/jats:p><\/jats:sec>","DOI":"10.25011\/cim.v45i4.38934","type":"journal-article","created":{"date-parts":[[2022,12,31]],"date-time":"2022-12-31T16:14:34Z","timestamp":1672503274000},"page":"E16-E24","source":"Crossref","is-referenced-by-count":1,"title":["Changes in Vector Astigmatism After Superotemporal Versus Temporal Clear Corneal Incision Cataract Surgery"],"prefix":"10.3138","volume":"45","author":[{"given":"Zhennan","family":"Zhao","sequence":"first","affiliation":[{"name":"Eye Institute and Department of Ophthalmology, Eye & ENT Hospital, Fudan University, Shanghai, China"},{"name":"NHC Key Laboratory of Myopia (Fudan University); Key Laboratory of Myopia, Chinese Academy of Medical Sciences, Shanghai, China"},{"name":"Shanghai Key Laboratory of Visual Impairment and Restoration, Shanghai, China"},{"name":"Shanghai Research Center of Ophthalmology and Optometry, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Fan","sequence":"additional","affiliation":[{"name":"Eye Institute and Department of Ophthalmology, Eye & ENT Hospital, Fudan University, Shanghai, China"},{"name":"NHC Key Laboratory of Myopia (Fudan University); Key Laboratory of Myopia, Chinese Academy of Medical Sciences, Shanghai, China"},{"name":"Shanghai Key Laboratory of Visual Impairment and Restoration, Shanghai, China"},{"name":"Shanghai Research Center of Ophthalmology and Optometry, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongxiang","family":"Jiang","sequence":"additional","affiliation":[{"name":"Eye Institute and Department of Ophthalmology, Eye & ENT Hospital, Fudan University, Shanghai, China"},{"name":"NHC Key Laboratory of Myopia (Fudan University); Key Laboratory of Myopia, Chinese Academy of Medical Sciences, Shanghai, China"},{"name":"Shanghai Key Laboratory of Visual Impairment and Restoration, Shanghai, China"},{"name":"Shanghai Research Center of Ophthalmology and Optometry, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Lu","sequence":"additional","affiliation":[{"name":"Eye Institute and Department of Ophthalmology, Eye & ENT Hospital, Fudan University, Shanghai, China"},{"name":"NHC Key Laboratory of Myopia (Fudan University); Key Laboratory of Myopia, Chinese Academy of Medical Sciences, Shanghai, China"},{"name":"Shanghai Key Laboratory of Visual Impairment and Restoration, Shanghai, China"},{"name":"Shanghai Research Center of Ophthalmology and Optometry, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1696","container-title":["Clinical and Investigative Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/cimonline.ca\/index.php\/cim\/article\/download\/38934\/30506","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/utppublishing.com\/doi\/pdf\/10.25011\/cim.v45i4.38934","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,13]],"date-time":"2025-03-13T18:12:10Z","timestamp":1741889530000},"score":1,"resource":{"primary":{"URL":"https:\/\/utppublishing.com\/doi\/10.25011\/cim.v45i4.38934"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,12,31]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2022,12,31]]}},"alternative-id":["10.25011\/cim.v45i4.38934"],"URL":"https:\/\/doi.org\/10.25011\/cim.v45i4.38934","relation":{},"ISSN":["1488-2353"],"issn-type":[{"value":"1488-2353","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,12,31]]}}}
