At the time of explantation, patients were 72 years old on average (\u00b115.41; min 2 years; max 96 years). The most common reason for explantation (60%) was dislocation or subluxation of the IOL, followed by IOL opacities (18%), corneal decompensation associated with anterior chamber lenses (9%), visual disturbance in the refractive IOL (4%), refractive error (4%), cataract development due to phakic IOL (4%) and Uveitis-Glaucoma-Hyphema Syndrome (1%). Over the years, there has been an increase in IOL explantations. For all reasons for explantation, the median interval between primary IOL implantation and IOL replacement was 54 month (IQR, 3.6-132 months). All opacified IOLs exhibited calcification. Secondarily implanted IOLs most commonly used iris fixation (57%), followed by sulcus fixation (22%), capsular bag fixation (17%) and scleral fixation (4%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The most common reason seen for explantation was IOL dislocation, and the most common refixation site was the iris.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11206721261473643","type":"journal-article","created":{"date-parts":[[2026,8,31]],"date-time":"2026-08-31T14:19:31Z","timestamp":1788185971000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["IOL replacement: A retrospective long-term analysis to assess the reasons and the frequency of intraocular lens explantation"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-8730-9519","authenticated-orcid":false,"given":"Matthias","family":"Gotthardt","sequence":"first","affiliation":[{"name":"Klinikum Ernst von Bergmann gGmbH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mandana","family":"Keen","sequence":"additional","affiliation":[{"name":"Klinikum Ernst von Bergmann gGmbH"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ann-Sophie","family":"Lindenberg","sequence":"additional","affiliation":[{"name":"practice Dr. Niemeyer and colleagues, Potsdam, Brandenburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ameli","family":"Gabel-Pfisterer","sequence":"additional","affiliation":[{"name":"Klinikum Ernst von Bergmann gGmbH"},{"name":"Department of Ophthalmology, Brandenburg Medical School Theodor Fontane (MHB), University Hospital Brandenburg, Brandenburg\/ Havel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anja","family":"Liekfeld","sequence":"additional","affiliation":[{"name":"Klinikum Ernst von Bergmann gGmbH"},{"name":"Technische Hochschule Brandenburg, Brandenburg\/ Havel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.2147\/OPTH.S436963"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-019-49030-2"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajo.2017.12.016"},{"key":"e_1_3_4_5_2","first-page":"579","article-title":"A pilot study of intraocular lens explantation in 69 eyes in Chinese patients","volume":"10","author":"Chai F","unstructured":"Chai F, Ma B, Yang XG, et al.
