Corneal endothelial damage after cataract surgery in eyes with pseudoexfoliation syndrome

Abstract

Objective To compare corneal endothelial cell damage after cataract surgery in eyes with and without pseudoexfoliation (PXF).Methods From February 2011 to July 2013,32 eyes with PXF after phacoemulsification were regarded as experimental group and 37 normal eyes as control group.Preoperatively,1 month and 3 months postoperatively,corneal endothelia cell density (ECD) and central corneal thickness (CCT)were measured by non-contact specular microscope and Pentacam HD.Results The mean ECD was significantly lower in the PXF group than in the non-PXF group preoperatively and postoperatively; the mean CCT was similar between groups throughout the follow-up period; however,1 month and 3 months postoperatively,the percentage of endothelial cell loss was significantly greater in the PXF group than in the non-PXF group; the percentage increase in CCT was significantly greater in the PXF group than in the non-PXF group 1 month postoperatively.Conclusions Corneal endothelial cell loss and transient in CCT are greater after cataract in eyes with PXF than in eyes without PXF.
