Efficacy and Safety of Femtosecond Laser-Assisted Corneal Endothelial Keratoplasty: A Randomized Multicenter Clinical Trial

Abstract

FLEK effectively reduces postoperative astigmatism and results in an absence of wound healing related problems in patients with endothelial disease. However, visual acuity is lower as compared with conventional PK, and the high level of endothelial cell loss warrants a modification of the insertion technique of the endothelial graft.
