A Comparison Between Full Thickness and Partial Thickness Corneal Transplantation for Corneal Edema

This study has been completed.
Information provided by:
Mayo Clinic Identifier:
First received: June 27, 2006
Last updated: January 14, 2010
Last verified: January 2010
The objectives of this study are to compare the visual and refractive outcomes of deep lamellar endothelial keratoplasty (DLEK) with penetrating keratoplasty as treatment for certain cases of corneal edema due to endothelial decompensation. Additionally, data will be collected to compare corneal shape, corneal thickness, endothelial cell density, keratocyte density, corneal sensitivity, light scatter, and subjective visual function between the two procedures.
