To evaluate the efficacy and safety of MyoRing implantation in eyes with keratoconus managed at a tertiary eye hospital in the Eastern Province of Saudi Arabia. <jats:italic>Methods<\/jats:italic>. This one-armed historical cohort study included keratoconus patients operated for MyoRing implant. The cases were assessed before and 6\u2009months after surgery. Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), spherical equivalent (SE), central corneal thickness (CCT), and corneal curvature (Kmean) were noted and measured before and 6\u2009months after the intervention. Intra- and postoperative complications were noted. <jats:italic>Result<\/jats:italic>. We studied 12 eyes of 12 patients with moderate keratoconus. The median of Kmean was 50.6\u2009mm (IQR 47.54; 52.5) and 44.5\u2009mm (IQR 42.5; 46.8) before and 6\u2009months after surgery. The change in Kmean was significant (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.002<\/mml:mn><\/mml:mrow><\/mml:math>). The median spherical equivalent (SE) was \u22125.1D (interquartile range (IQR) 7.1; \u22123.6) and \u22120.6 (IQR \u22122.1; 0.8) before and 6\u2009months after surgery. The difference in SE was significant (Wilcoxon signed-rank test <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mrow><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.004<\/mml:mn><\/mml:mrow><\/mml:math>). The CCT was 447\u2009\u00b1\u200934\u2009<jats:italic>\u03bc<\/jats:italic>m and 444\u2009\u00b1\u200930\u2009<jats:italic>\u03bc<\/jats:italic>m before and 6\u2009months after surgery, respectively. The CCT change was not significant (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><mml:mrow><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.26<\/mml:mn><\/mml:mrow><\/mml:math>). The UCVA and BCVA improved by 2 or more lines in 9 (75%) eyes, remained stable in 2 (16.7%) eyes, and decreased in 2 (16.7%) eyes. <jats:italic>Conclusion<\/jats:italic>. MyoRing implant seems to be a safe and effective procedure to manage low and moderate keratoconus. The outcomes could be further enhanced by additional procedures such as collagen cross-linkage and photorefractive keratectomy if warranted.<\/jats:p>","DOI":"10.1155\/2019\/2630704","type":"journal-article","created":{"date-parts":[[2019,8,29]],"date-time":"2019-08-29T19:30:56Z","timestamp":1567107056000},"page":"1-4","source":"Crossref","is-referenced-by-count":3,"title":["Outcomes of MyoRing Implantation in Eyes with Keratoconus in the Eastern Province of Saudi Arabia: \u201cA Single-Arm Cohort Study\u201d"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0717-9424","authenticated-orcid":true,"given":"Yousef Saad","family":"Alshammari","sequence":"first","affiliation":[{"name":"Division of Cornea and External Eye Disease Segment, Dhahran Eye Specialist Hospital, Dhahran, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3359-7646","authenticated-orcid":true,"given":"Abdulaziz Ismail","family":"Al Somali","sequence":"additional","affiliation":[{"name":"Division of Cornea and External Eye Disease, Department of Ophthalmology, King Faisal University, Al Ahsa, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.4103\/0301-4738.116070"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/s10792-017-0699-8"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.clae.2016.10.001"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.4103\/0301-4738.151468"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.joco.2017.07.003"},{"issue":"3","key":"6","first-page":"399","volume":"20","year":"2015","journal-title":"Zagazig University Medical Journal"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s40123-017-0099-1"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1136\/bjophthalmol-2017-311391"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.2005.074955"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.3980\/j.issn.2222-3959.2014.05.11"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.4103\/0974-9233.90136"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.3928\/1081597x-20121228-04"},{"issue":"4","key":"13","first-page":"206","volume":"1","year":"2010","journal-title":"Journal of Emmetropia"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2010.12.012"},{"key":"15","first-page":"241","volume-title":"Can we improve visual acuity after intrastromal corneal ring segments implantation for keratoconus and post LASIK ectasia","year":"2019"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-9071.2011.02698.x"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.17116\/oftalma201713334-8"},{"issue":"2","key":"18","first-page":"87","volume":"71","year":"2015","journal-title":"Ceska\u0301 a Slovenska\u0301 Oftalmologie: Casopis Ceske\u0301 Oftalmologicke\u0301 Spolecnosti a Slovenske\u0301 Oftalmologicke\u0301 Spolecnosti"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-015-3231-"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1186\/s40662-016-0040-z"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2009.05.036"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1016\/j.optom.2016.01.002"}],"container-title":["Journal of Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/joph\/2019\/2630704.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/joph\/2019\/2630704.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/joph\/2019\/2630704.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,29]],"date-time":"2019-08-29T19:31:02Z","timestamp":1567107062000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/joph\/2019\/2630704\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,8,29]]},"references-count":22,"alternative-id":["2630704","2630704"],"URL":"https:\/\/doi.org\/10.1155\/2019\/2630704","relation":{},"ISSN":["2090-004X","2090-0058"],"issn-type":[{"value":"2090-004X","type":"print"},{"value":"2090-0058","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,8,29]]}}}
