Patients received either a preoperative laser PI or intraoperative surgical iridectomy. Eyes were matched according to gender, age, presence of preoperative posterior stromal ripples, baseline visual acuity and corneal thickness. Pre\u2010 and post\u2010operative inflammation was quantified using AS\u2010OCT measured aqueous\u2010to\u2010air relative intensity (ARI) and anterior chamber (AC) cell reflectivity. Post\u2010operative trends in subclinical inflammation were compared using generalized additive models (GAM). Visual, pachymetric and endothelial outcomes, as well as post\u2010operative complications, were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The laser PI group showed greater baseline ARI (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) consistent with higher preoperative subclinical inflammation, while surgical iridectomy eyes exhibited greater cell counts after DMEK and at final follow\u2010up (both\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.05).
