Methods: All participants underwent complete biocular examinations. Scheimpflug tomography data from 66 eyes of 33 patients were registered. The interocular symmetry was based on five patterns: morphogeometric symmetry, axial symmetry at the corneal vertex, angular-spatial symmetry, direct symmetry (equal octants), and enantiomorphism (mirror octants). Results: No statistically significant differences were found between right and left eyes in corneal morphogeometric (p \u2265 0.488) and aberrometric parameters (p \u2265 0.102). Likewise, no statistically significant differences were found in any of the axial symmetry parameters analyzed (p \u2265 0.229), except in the surface rotation angle beta (p = 0.102) and translation coordinates X0 and Y0 (p &lt; 0.001) for the anterior corneal surface, and the rotation angle gamma (p &lt; 0.001) for the posterior surface. Similarly, no statistically significant differences were identified for direct symmetry (p \u2265 0.20) and enantiomorphism (p \u2265 0.75), except for some elevation data in the posterior surface (p &lt; 0.01). Conclusions: The level of symmetry of both corneas of a healthy individual is high, with only some level of disparity between fellow corneas in rotation and translation references. Abnormalities in this pattern of interocular asymmetry may be useful as a diagnostic tool.<\/jats:p>","DOI":"10.3390\/sym10100453","type":"journal-article","created":{"date-parts":[[2018,10,2]],"date-time":"2018-10-02T08:23:50Z","timestamp":1538468630000},"page":"453","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Assessment of Pattern and Shape Symmetry of Bilateral Normal Corneas by Scheimpflug Technology"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8391-0688","authenticated-orcid":false,"given":"Francisco","family":"Cavas-Mart\u00ednez","sequence":"first","affiliation":[{"name":"Department of Graphical Expression, Technical University of Cartagena, 30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Pi\u00f1ero","sequence":"additional","affiliation":[{"name":"Group of Optics and Visual Perception, Department of Optics, Pharmacology and Anatomy, University of Alicante, 03690 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1504-8475","authenticated-orcid":false,"given":"Daniel","family":"Fern\u00e1ndez-Pacheco","sequence":"additional","affiliation":[{"name":"Department of Graphical Expression, Technical University of Cartagena, 30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Mira","sequence":"additional","affiliation":[{"name":"Department of Graphical Expression, Technical University of Cartagena, 30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco","family":"Ca\u00f1avate","sequence":"additional","affiliation":[{"name":"Department of Graphical Expression, Technical University of Cartagena, 30202 Cartagena, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Ali\u00f3","sequence":"additional","affiliation":[{"name":"Keratoconus Unit of Vissum Corporation Alicante, 03016 Alicante, Spain"},{"name":"Department of Ophthalmology, Miguel Hern\u00e1ndez University of Elche, 03202 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1085","DOI":"10.1016\/j.jbiomech.2016.02.037","article-title":"Exploration of the validity of the two-dimensional sagittal plane assumption in modeling the standing long jump","volume":"49","author":"Hickox","year":"2016","journal-title":"J.
