The study consists of two parts: a retrospective and a prospective part. All patients in the retrospective part were operated by epi-off, while in the prospective part, the epi-on procedure was used. Also, other machines were used as Peschke Vario, Peschke Phoenix, and different types of riboflavin.

The effect of CXL was continued in 20% of cases, over a period of 3\u20135\u00a0years, some cases needed to repeat CXL due to the progression of corneal ectasia after cross-linking, in six eyes, that were rubbing their eyes and\/or hormonal disturbance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Corneal collagen cross-linking CXL is an effective method to prevent the progression of corneal ectasia, whether primary or post-laser\u2013assisted in situ keratomileusis, and the effect was stable over the years of study.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1120672120928921","type":"journal-article","created":{"date-parts":[[2020,6,5]],"date-time":"2020-06-05T02:24:50Z","timestamp":1591323890000},"page":"951-958","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Ten years experience of corneal collagen cross-linking"],"prefix":"10.1177","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4221-8932","authenticated-orcid":false,"given":"Ahmed","family":"Elmassry","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Alexandria University, Alexandria, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osama Ibrahim","family":"Said Ahmed","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Alexandria University, Alexandria, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9905-9472","authenticated-orcid":false,"given":"Moones F","family":"Abdalla","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Alexandria University, Alexandria, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karim","family":"Gaballah","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Helwan University, Helwan, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,6,4]]},"reference":[{"key":"bibr1-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-7020-6660-3.00026-5"},{"key":"bibr2-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2018.10.021"},{"key":"bibr3-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2016.12.015"},{"key":"bibr4-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1038\/eye.2015.63"},{"key":"bibr5-1120672120928921","doi-asserted-by":"publisher","DOI":"10.4103\/0301-4738.109523"},{"key":"bibr6-1120672120928921","doi-asserted-by":"publisher","DOI":"10.5812\/ircmj.28974"},{"key":"bibr7-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2008.08.021"},{"key":"bibr8-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1097\/ICO.0000000000000556"},{"key":"bibr9-1120672120928921","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20070101-17"},{"key":"bibr10-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1038\/eye.2013.130"},{"key":"bibr11-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1006\/exer.1997.0410"},{"key":"bibr12-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2009.03.035"},{"key":"bibr13-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1007\/s00347-012-2682-0"},{"key":"bibr14-1120672120928921","doi-asserted-by":"publisher","DOI":"10.4274\/tjo.89587"},{"key":"bibr15-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1016\/j.joco.2016.01.009"},{"key":"bibr16-1120672120928921","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2016.01.040"},{"key":"bibr17-1120672120928921","unstructured":"Krueger RR and Spoerl EHS.
