Visual acuity, refraction, corneal astigmatism, tonometry, and endothelial cell density were recorded preoperatively and postoperatively. Surgically induced astigmatism (SIA) was calculated using vector analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>No intraoperative complications were noted. One day after surgery, the quantity of cells in the anterior chamber was significantly lower in TCI group than in STI group (p=0.019). The percentage of eyes with uncorrected visual acuity (UCVA) of \u226520\/25 was 41.2% for TCI and 17.1% for STI; the difference was statistically significant (p=0.03), but not thereafter. The mean corneal astigmatism was significantly lower in the TCI group than in the STI group (p=0.01) 3 months postoperatively and subsequently. No significant between-group difference in SIA was found during the follow-up. There was no significant difference in best-corrected visual acuity and endothelial cell loss between groups, postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The TCI and STI techniques are comparable in terms of safety and induction of astigmatism for the rigid iris-fixated PIOL implantation. However, the TCI is easy to perform and provides a faster visual recovery and lower postoperative corneal astigmatism compared with the STI.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.5301\/ejo.5000058","type":"journal-article","created":{"date-parts":[[2011,9,16]],"date-time":"2011-09-16T12:49:06Z","timestamp":1316177346000},"page":"114-119","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Rigid Iris-Fixated Phakic Lens Implantation for High Myopia: Novel Trapezoidal Corneal versus Scleral Incisions"],"prefix":"10.1177","volume":"22","author":[{"given":"Kai Jie","family":"Wang","sequence":"first","affiliation":[{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology & Visual Sciences Key Lab, Beijing - China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ning Li","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology & Visual Sciences Key Lab, Beijing - China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feng Ju","family":"Zhang","sequence":"additional","affiliation":[{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology & Visual Sciences Key Lab, Beijing - China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Si Quan","family":"Zhu","sequence":"additional","affiliation":[{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology & Visual Sciences Key Lab, Beijing - China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,9,16]]},"reference":[{"key":"bibr1-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2004.08.057"},{"key":"bibr2-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2006.09.029"},{"key":"bibr3-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2007.04.009"},{"key":"bibr4-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2007.05.036"},{"key":"bibr5-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(00)00545-9"},{"key":"bibr6-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2008.12.059"},{"key":"bibr7-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1097\/00055735-199002000-00014"},{"key":"bibr8-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(00)00484-3"},{"key":"bibr9-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(99)00082-2"},{"key":"bibr10-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(98)80173-9"},{"key":"bibr11-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/S0886-3350(96)80273-2"},{"key":"bibr12-ejo.5000058","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2009.11.041"}],"container-title":["European Journal of Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.5301\/ejo.5000058","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.5301\/ejo.5000058","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.5301\/ejo.5000058","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T19:36:52Z","timestamp":1777405012000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.5301\/ejo.5000058"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,9,16]]},"references-count":12,"journal-issue":{"issue":"7_suppl","published-print":{"date-parts":[[2012,4]]}},"alternative-id":["10.5301\/ejo.5000058"],"URL":"https:\/\/doi.org\/10.5301\/ejo.5000058","relation":{},"ISSN":["1120-6721","1724-6016"],"issn-type":[{"value":"1120-6721","type":"print"},{"value":"1724-6016","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,9,16]]}}}
