Patients with FECD that underwent DMEK surgery were included in this retrospective study. Scheimpflug Tomography was carried out in order to calculate chord mu and chord alpha lengths prior to surgery and at 3 and 12 months postoperative. This study included 27 eyes from 27 patients. Significant changes in chord mu were observed within the first three months (from 0.47 \u00b1 0.32 to 0.29 \u00b1 0.21 mm, p &lt; 0.01) and remained stable 12 months postoperative (0.30 \u00b1 0.21 mm, p &gt; 0.05). However, chord alpha remained stable throughout the 12 months post surgery (from 0.53 \u00b1 0.19 to 0.49 \u00b1 0.14 mm, p &gt; 0.05). In addition to the pupillary center distance from the corneal center (from 0.35 \u00b1 0.25 to 0.34 \u00b1 0.20 mm, p &gt; 0.05) also remain stable. In FECD patients undergoing DMEK surgery, chord mu length decreased, and chord alpha length remained stable after 12 months of follow-up.<\/jats:p>","DOI":"10.3390\/jcm10214844","type":"journal-article","created":{"date-parts":[[2021,10,22]],"date-time":"2021-10-22T00:22:02Z","timestamp":1634862122000},"page":"4844","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Chord Mu (\u00b5) and Chord Alpha (\u03b1) Length Changes in Fuchs Endothelial Corneal Dystrophy before and after Descemet Membrane Endothelial Keratoplasty (DMEK) Surgery"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7464-2493","authenticated-orcid":false,"given":"Carlos","family":"Rocha-de-Lossada","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Hospital Clinic de Barcelona Institut Clinic d\u2019Oftalmologia, 08036 Barcelona, Spain"},{"name":"Department of Ophthalmology (Qvision), VITHAS Hospital, 04120 Almer\u00eda, Spain"},{"name":"Department of Ophthalmology, Hospital Virgen de las Nieves, 18014 Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0450-7717","authenticated-orcid":false,"given":"Jos\u00e9-Mar\u00eda","family":"S\u00e1nchez-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Physics of Condensed, Optics Area, University of Seville, 41012 Seville, Spain"},{"name":"Department of Ophthalmology (Tecnolaser Clinic Vision\u00ae), Refractive Surgery Centre, 41018 Seville, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6952-5647","authenticated-orcid":false,"given":"Davide","family":"Borroni","sequence":"additional","affiliation":[{"name":"Department of Doctoral Studies, Riga Stradins University, LV-1007 Riga, Latvia"},{"name":"Department of Ophthalmology, Royal Liverpool University Hospital, Liverpool L7 8XP, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V\u00edctor","family":"Llorens-Bell\u00e9s","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hospital Clinic de Barcelona Institut Clinic d\u2019Oftalmologia, 08036 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5901-2469","authenticated-orcid":false,"given":"Rahul","family":"Rachwani-Anil","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Antequera Hospital, 29200 Malaga, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6995-1291","authenticated-orcid":false,"given":"Josep","family":"Torras-Sanvicens","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hospital Clinic de Barcelona Institut Clinic d\u2019Oftalmologia, 08036 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5148-7643","authenticated-orcid":false,"given":"Vito","family":"Romano","sequence":"additional","affiliation":[{"name":"Department of Doctoral Studies, Riga Stradins University, LV-1007 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Peraza-Nieves","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hospital Clinic de Barcelona Institut Clinic d\u2019Oftalmologia, 08036 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"91","DOI":"10.1016\/j.ajo.2018.01.018","article-title":"Trends in Corneal Transplantation from 2001 to 2016 in Germany: A Report of the DOG\u2013Section Cornea and its Keratoplasty Registry","volume":"188","author":"Flockerzi","year":"2018","journal-title":"Am.
