We present a hands-free method for augmenting posterior pressure by temporarily tucking cellulose sponges under the blades of the eyelid speculum. The sponges transfer some of the eyelid speculum\u2019s weight onto the bulbar surface posterior to the iris, thereby indenting the sclera and causing the iris diaphragm to bulge further forward. This hands-free technique can transform a potentially challenging DMEK case into a more straightforward one by facilitating both a shallow anterior chamber and a bimanual unscrolling technique. However, it only works in bicameral eyes with a vitreous body (e.g., an eye with penetrating keratoplasty, vitreous syneresis, and axial myopia) and will not work in unicameral eyes after vitrectomy (e.g., an eye with an Anterior Chamber Intraocular Lens (ACIOL)).<\/jats:p>","DOI":"10.4103\/ijo.ijo_1385_23","type":"journal-article","created":{"date-parts":[[2024,2,6]],"date-time":"2024-02-06T01:00:14Z","timestamp":1707181214000},"page":"S533-S535","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Chamber shallowing technique for challenging DMEK cases: Tucking cellulose spears under the speculum to augment posterior pressure"],"prefix":"10.4103","volume":"72","author":[{"given":"Yong","family":"Kam","sequence":"first","affiliation":[{"name":"Moyes Eye Center, Kansas City, MO, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Kigin","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Science, Roy J. and Lucille A.
