This technically challenging surgery involves several critical steps such as graft unfolding, positioning and correct orientation. Severe pre-existing corneal oedema limits visibility and prolongs the surgical duration, adversely affecting the success. We present two cases of severe corneal oedema, poor anterior chamber visualisation, wherein we performed endoilluminator-assisted DMEK (E-DMEK). This helped in intraoperative visualisation, reduced the surgical time and reduced graft manipulation. Postoperatively, both patients showed significant improvement in visual acuity (from counting fingers to 20\/80 and 20\/30) and reduced corneal thickness (556 and 484 microns) at 6\u2009months. The endoilluminator is a practical and cost-effective modification that improves surgical outcomes for both experienced and novice surgeons, expanding the indications for DMEK and ensuring successful postoperative results.<\/jats:p>","DOI":"10.1136\/bcr-2025-265207","type":"journal-article","created":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T23:15:15Z","timestamp":1748387715000},"page":"e265207","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Endoilluminator\u2013assisted
