The changes of corneal endothelium by laser peripheral iridectomy

Objective To explore the changes of corneal endothelium of peripheral iridectomy by using Nd∶YAG laser.Methods The corneal endothelium using non contact corneal endothelium microscope of the 40 eyes,which had been subjected to the treatment of peripheral iridectomy by using Nd∶YAG laser were observed.Average,Maximum and Minimum cell area; Cell Density,Cell Variation,cell area SD of corneal endothelium were observed 1 week,1 month,3 months,and 6months postoperatively.The effect of laser treatment was analyzed with SAS Version 9.12 Mixed Model.Results There was significant correlation among Average and Maximum cell area,Cell Density,Cell Variation,cell area SD of corneal endothelium compared before and after operation.There was no significant correlation among Minimum cell area.Conclusions The Nd∶YAG laser peripheral iridectomy damages the corneal endothelium in certain degree.
