Schrittenlocher S, et al. - Authors analyzed 1084 eyes [undergone Descemet Membrane Endothelial Keratoplasty (DMEK) alone or combined with cataract surgery (triple-DMEK)] from July 2011 to February 2016 to estimate the extent of visual acuity (VA) outcome prediction by evaluating preoperative VA after DMEK. They observed 40% chances for preoperative VA of 20/200 to reach postoperative VA above 20/25 with 50% for preoperative VA of 20/60 and > 60% for preoperative VA of 20/40. They observed good results of DMEK even in eyes with very poor preoperative vision caused by corneal pathology though, preoperative visual acuity values below 20/100 resulted in a significantly poorer visual recovery implying preoperative visual acuity as an adjuvant tool for the forecast of the final visual outcome after DMEK.
