Before surgery and at 1 month and 3 months after surgery, corneal topography was measured with a rotating Scheimpflug camera. Both preoperative and postoperative corneal astigmatism were calculated in 2 ways: total corneal astigmatism and keratometric astigmatism. Polar analysis was used to evaluate the flattening and torque effect of steep meridian incisions on corneal astigmatism.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Total corneal astigmatism changed significantly after 3 months (p = 0.005) and univariate analysis revealed a significant change 0.25D \u00b1 0.36 D in astigmatic polar value AKP(+45) of total corneal astigmatism (p = 0.047). A decrease in AKP(+0) was observed in both keratometric and total astigmatism at 1 and 3 months, although the decreases were not statistically significant (p = 0.394, p = 0.442, p = 0.602, p = 0.503, respectively).<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Steep meridian incision performed on the preoperative steeper meridian of keratometric astigmatism may cause a significant torsional effect on total corneal astigmatism as well as reducing the astigmatism along the meridian.<\/jats:p>\n <\/jats:sec>","DOI":"10.5301\/ejo.5000575","type":"journal-article","created":{"date-parts":[[2015,2,6]],"date-time":"2015-02-06T07:29:46Z","timestamp":1423207786000},"page":"422-425","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Effect of Steep Meridian Clear Corneal Incisions in Phacoemulsification"],"prefix":"10.1177","volume":"25","author":[{"given":"Wenjun","family":"Song","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Peking University Third Hospital, Beijing - China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoyong","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Peking University Third Hospital, Beijing - China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Peking University Third Hospital, Beijing - China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,6,2]]},"reference":[{"key":"bibr1-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1097\/ICU.0b013e328319c27a"},{"key":"bibr2-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1097\/ICU.0b013e32835ac853"},{"key":"bibr3-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2011.11.031"},{"key":"bibr4-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2005.12.104"},{"key":"bibr5-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2005.08.046"},{"key":"bibr6-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2006.09.010"},{"key":"bibr7-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1111\/j.1444-0938.2010.00509.x"},{"key":"bibr8-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1111\/j.1755-3768.2009.01732.x"},{"key":"bibr9-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1111\/j.1755-3768.2008.01287.x"},{"key":"bibr10-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.3341\/kjo.2012.26.1.10"},{"key":"bibr11-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2008.09.027"},{"key":"bibr12-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2012.08.060"},{"key":"bibr13-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2013.06.027"},{"key":"bibr14-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(01)01279-2"},{"key":"bibr15-ejo.5000575","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20070501-16"}],"container-title":["European Journal of Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.5301\/ejo.5000575","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.5301\/ejo.5000575","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.5301\/ejo.5000575","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T19:38:22Z","timestamp":1777405102000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.5301\/ejo.5000575"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,6,2]]},"references-count":15,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2015,9]]}},"alternative-id":["10.5301\/ejo.5000575"],"URL":"https:\/\/doi.org\/10.5301\/ejo.5000575","relation":{},"ISSN":["1120-6721","1724-6016"],"issn-type":[{"value":"1120-6721","type":"print"},{"value":"1724-6016","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,6,2]]}}}
