The changes of corneal endothelium after laser therapy

Objectives To explore the changes of corneal endothelium after the Nd:YAG and 532nm laser therapy.Methods Use the corneal endothelium microscope to observe the corneal endothelium of the eyes which had been subjected to the treatment of posterior capsular opacification and peripheral iridectomy by using the Nd:YAG laser and to observe the corneal endothelium of the eyes which had been subjected to the treatment by using the 532nm laser.Results Among the entire Nd:YAG laser sufferer,14 days later,in the center of the corneal endothelium,the decrease of the cell density revealed statistically significant difference(P0.05).After the treatment of peripheral iridectomy,14 days later,in the center of the corneal endothelium,the decrease of the cell density revealed statistically significant difference(P0.05).7 days later,in the periphery of the corneal endothelium,cell area;minimum cell area,cell density and percentage of hexagonal endothelium were analyzed statistically significant difference(P0.05).After the treatment of posterior capsular opacification,there was no significant correlation between pre-and postoperative central and 6 o'clock periphery of corneal endothelium in 7 and 14 days(P0.05).There was no significant correlation between pre-and postoperative central and 6 o'clock periphery of corneal endothelium in central serous choroidoretinopathy and diabetic retinopathy treatment(P0.05).Conclusion The Nd:YAG laser peripheral iridectomy will damage to corneal endothelium.The treatment of central serous choroidoretinopathy and diabetic retinopathy by using the 532nm laser will not do the statistically significant damage to the corneal endothelium.
