Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, refractive and corneal astigmatism changes and corneal coupling correction were evaluated preoperatively, 1 and 12mo postoperatively. Vector analysis was used for astigmatism changes. Coefficient of adjustment (CAdj) was calculated for corneal coupling analysis.\nRESULTS: The mean UDVA achieved was 0.03 logMAR at 1mo and remained unchanged throughout the whole follow-up (P=0.193). At the last visit, 84% of the eyes achieved a CDVA of 0.00 logMAR or better. Regarding spherical equivalent refraction (SEQ), 96% of eyes were ranges of \u00b11.00 D and 84% of them within \u00b10.50 D. Also, 94% of eyes had a remaining refractive cylinder within \u00b11.00 D and 78% of them within \u00b10.50 D. Both, SEQ and refractive cylinder, remain stable over the postoperative follow-up (P=1.000 and P=0.660, respectively). In terms of surgically induced astigmatism (SIA), no statistically significant differences were found over the follow-up (P=0.102) and under correction was found with a correction index lower than the unit at each visit. A keratometric astigmatism induced of 0.59\u00b10.53 (vector mean: 0.26\u00d773\u00ba) D was reached at the last visit. No significant changes in terms of corneal astigmatism orientation were reported over post-surgery visits (P=0.129 and P=0.097 at 1 and 12mo respectively). No clinical significance was found for CAdj on with-the-rule astigmatism. No postoperative complications resulting from the surgery were found.\nCONCLUSION: Refractive outcomes suggest that the V4c T-ICL implantation for correction of myopic astigmatism was satisfactory in terms of effectiveness, safety, and stability during 1y of follow-up. Corneal astigmatism induced by the incision around 0.5 D is achieved according to the remaining refractive cylinder found at one-year post-surgery. Corneal coupling analysis results in no unexpected spherical change.<\/jats:p>","DOI":"10.18240\/ijo.2024.07.18","type":"journal-article","created":{"date-parts":[[2024,6,25]],"date-time":"2024-06-25T08:46:49Z","timestamp":1719305209000},"page":"1322-1330","source":"Crossref","is-referenced-by-count":3,"title":["Refractive outcomes after V4c Toric collamer lens implantation over 1y of follow-up"],"prefix":"10.18240","volume":"17","author":[{"name":"Vithas Eurocanarias, Las Palmas de Gran Canaria 35004, Spain","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Humberto","family":"Carreras-D\u00edaz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda del Rosario","family":"Carreras-D\u00edaz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"University Hospital of Girona Doctor Josep Trueta, Gerona 17007, Spain","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amalia","family":"Lorente-Vel\u00e1zquez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Departament of Optometry and Vision, Faculty of Optics and Optometry, Complutense University of Madrid, Madrid 28040, Spain","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"http:\/\/ies.ijo.cn\/en_publish\/2024\/7\/20240718.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,6,25]],"date-time":"2024-06-25T08:47:15Z","timestamp":1719305235000},"score":1,"resource":{"primary":{"URL":"http:\/\/ies.ijo.cn\/gjyken\/ch\/reader\/view_abstract.aspx?file_no=20240718&flag=1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,7,18]]},"references-count":0,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2024,7,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2024.07.18","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,7,18]]}}}
