A retrospective interventional case series study including a total of 33 keratoconus eyes (age 8 to 17 years) that had undergone ICRS (Keraring segments, Mediphacos) implantation was conducted. Information about visual, refractive, pachymetric, corneal topographic and aberrometric, and corneal endothelial changes during a 3-month follow-up were extracted and analysed. A significant improvement was observed in logMAR corrected distance visual acuity (p = 0.005), combined with a statistically significant reduction in keratometric readings (p &lt; 0.001). A reduction in the magnitude of corneal astigmatism of \u22651 D was observed in 52.8% of eyes. No significant changes were observed in corneal endothelial density (p = 0.317). Significant changes were found in the anterior vertical coma component (p = 0.002) as well as in the spherical aberration of the posterior corneal surface (p = 0.004). Only two relevant complications were described: one corneal microperforation with penetration of the ring segment into the anterior chamber (1 eye, 2.8%), and a case of ring extrusion (1 eye, 2.8%). ICRS implantation in children keratoconus eyes allows a reduction of corneal astigmatism, irregularity, and aberrations, leading to a significant visual improvement.<\/jats:p>","DOI":"10.3390\/vision5010001","type":"journal-article","created":{"date-parts":[[2020,12,23]],"date-time":"2020-12-23T12:19:51Z","timestamp":1608725991000},"page":"1","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Intracorneal Ring Segment Implantation for the Management of Keratoconus in Children"],"prefix":"10.3390","volume":"5","author":[{"given":"Pablo","family":"Larco","sequence":"first","affiliation":[{"name":"Cl\u00ednica Larco Visi\u00f3n, Quito 170135, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9933-1528","authenticated-orcid":false,"suffix":"Jr.","given":"Pablo","family":"Larco","sequence":"additional","affiliation":[{"name":"Cl\u00ednica Larco Visi\u00f3n, Quito 170135, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Torres","sequence":"additional","affiliation":[{"name":"Cl\u00ednica Larco Visi\u00f3n, Quito 170135, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1546-4807","authenticated-orcid":false,"given":"David P.","family":"Pi\u00f1ero","sequence":"additional","affiliation":[{"name":"Department of Optics, Pharmacology and Anatomy, University of Alicante, 03690 Alicante, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"293","DOI":"10.1016\/0039-6257(84)90094-8","article-title":"Keratoconus and related noninflammatory corneal thinning disorders","volume":"28","author":"Krachmer","year":"1984","journal-title":"Surv.
