This condition occurs after uneventful cataract surgery with an in-the-bag intraocular lens (IOL). To address this issue, supplementary implantation of conventional three-piece IOLs in the sulcus or dedicated supplementary Rayner Sulcoflex\u00ae IOL have been used successfully. The aim of this retrospective case series was to assess the effectiveness of resolving ND using a supplementary 1stQ AddOn\u00ae (Medicontur) IOL. The 1stQ AddOn\u00ae has a different design and optic size compared to the Rayner Sulcoflex\u00ae. Patients experiencing severe and persistent ND underwent supplementary implantation of the 1stQ AddOn\u00ae IOL. The primary outcome measure was the resolution of dysphotopsia. Nine eyes received the 1stQ AddOn\u00ae IOL, with complete symptom resolution observed in 6 eyes, partial improvement in 1 eye, and no change in 2 eyes. This indicates that supplementary implantation of the 1stQ AddOn\u00ae IOL can effectively and safely treat ND, performing equally well as the Rayner Sulcoflex\u00ae. The positive impact of sulcus-fixated supplementary IOLs seems to be related to the interaction between the central optic and the pupil margin. <\/jats:p>","DOI":"10.1159\/000533686","type":"journal-article","created":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T21:16:36Z","timestamp":1697663796000},"page":"540-545","source":"Crossref","is-referenced-by-count":1,"title":["Supplementary Implantation of 1stQ AddOn\u00ae Sulcus-Fixated Intraocular Lens to Treat Negative Dysphotopsia: A Retrospective Case Series"],"prefix":"10.1159","author":[{"given":"Maxim","family":"Van Slycken","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guy","family":"Sallet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thierry","family":"Derveaux","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2023,10,13]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2008.06.026"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2020.08.009"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/s0886-3350(00)00611-8"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2016.09.016"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2016.11.049"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2017.11.013"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-015-3029-8"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2017.10.038"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2014.12.040"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-9071.2012.02833.x"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1080\/17469899.2018.1560263"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.3928\/1081-597X-20070501-06"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1117\/1.3656745"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2013.04.015"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1111\/aos.13508"}],"container-title":["Case Reports in Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/cop\/article-pdf\/14\/1\/540\/4016879\/000533686.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/cop\/article-pdf\/14\/1\/540\/4016879\/000533686.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:39:09Z","timestamp":1745422749000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000533686"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,10,13]]},"references-count":15,"URL":"https:\/\/doi.org\/10.1159\/000533686","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.24204114","asserted-by":"subject"}]},"ISSN":["1663-2699"],"issn-type":[{"type":"electronic","value":"1663-2699"}],"subject":[],"published":{"date-parts":[[2023,10,13]]}}}
