Effective endo-illumination is crucial for minimizing surgical risks and ensuring optimal outcomes by enhancing the visibility of ocular structures. Traditionally, endo-illuminators in vitreoretinal surgery have relied on xenon light sources provided by the vitrectomy system. However, light-emitting diode (LED) light sources have now emerged as a superior alternative, offering both high light intensity and increased reliability. We present our innovation: a 3D-printed portable LED illumination system that connects seamlessly with the optical fiber cables of contemporary vitreoretinal surgery equipment. This device provides a reliable alternative light source in emergencies, such as bulb failure or power outages, and can also function as supplemental illumination, particularly when a chandelier system is used for bimanual vitreoretinal procedures.<\/jats:p>","DOI":"10.4103\/ijo.ijo_2234_24","type":"journal-article","created":{"date-parts":[[2025,4,17]],"date-time":"2025-04-17T07:00:18Z","timestamp":1744873218000},"page":"912-915","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["The Retilight, a portable LED endo-illuminator"],"prefix":"10.4103","volume":"73","author":[{"given":"Prithvi","family":"Chandrakanth","sequence":"first","affiliation":[{"name":"Department of Vitreoretina, Dr. Chandrakanth Nethralaya, Kozhikode, Kerala, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shishir","family":"Verghese","sequence":"additional","affiliation":[{"name":"Department of Vitreoretina, Amita Eye Care, Tiruvalla, Kerala, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aishwarya","family":"Naik","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Mandya Institute of Medical Sciences, Mandya, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K","family":"Chandrakanth","sequence":"additional","affiliation":[{"name":"Department of Cataract and Refractive Surgery, Dr. Chandrakanth Nethralaya, Kozhikode, Kerala, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,4,17]]},"reference":[{"key":"R1-20260422","doi-asserted-by":"crossref","first-page":"162","DOI":"10.1016\/j.survophthal.2010.08.003","article-title":"Advantages and limitations of small gauge vitrectomy","volume":"56","author":"Thompson","year":"2011","journal-title":"Surv Ophthalmol"},{"key":"R2-20260422","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1016\/0002-9394(76)90200-2","article-title":"Improved vitrectomy illumination system","volume":"81","author":"Peyman","year":"1976","journal-title":"Am J Ophthalmol"},{"key":"R3-20260422","doi-asserted-by":"crossref","first-page":"242","DOI":"10.1097\/00006982-200204000-00025","article-title":"A new wide-angle endoillumination probe for use during vitrectomy","volume":"22","author":"Peyman","year":"2002","journal-title":"Retina"},{"key":"R4-20260422","doi-asserted-by":"crossref","first-page":"28","DOI":"10.1186\/s40942-016-0052-9","article-title":"Vitreoretinal instruments: Vitrectomy cutters, endoillumination and wide-angle viewing systems","volume":"2","author":"de Oliveira","year":"2016","journal-title":"Int J Retina Vitr"},{"key":"R5-20260422","doi-asserted-by":"crossref","first-page":"924","DOI":"10.1097\/IAE.0b013e3181f44269","article-title":"Light-emitting diode technology in vitreoretinal surgery","volume":"31","author":"Dithmar","year":"2011","journal-title":"Retina"},{"key":"R6-20260422","doi-asserted-by":"crossref","first-page":"377","DOI":"10.1016\/j.jfo.2022.10.007","article-title":"Retinal risk of endoillumination: A comparison of different ophthalmic illumination systems","volume":"46","author":"Fehler","year":"2023","journal-title":"J Fr Ophtalmol"},{"key":"R7-20260422","doi-asserted-by":"crossref","first-page":"851","DOI":"10.1515\/cdbme-2021-2217","article-title":"Vitrectome with integrated LED illumination: Development and testing","volume":"7","author":"Sieber","year":"2021","journal-title":"Curr Dir Biomed Eng"},{"key":"R8-20260422","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1159\/000475760","article-title":"Importance of light filters in modern vitreoretinal surgery: An update of the literature","volume":"58","author":"Coppola","year":"2017","journal-title":"Ophthalmic Res"}],"container-title":["Indian Journal of Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/IJO.IJO_2234_24","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T19:11:54Z","timestamp":1787166714000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/IJO.IJO_2234_24"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,17]]},"references-count":8,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.4103\/ijo.ijo_2234_24","relation":{},"ISSN":["0301-4738","1998-3689"],"issn-type":[{"value":"0301-4738","type":"print"},{"value":"1998-3689","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4,17]]},"assertion":[{"value":"2024-09-16","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-01-06","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
