The Changes Of Corneal Endothelium After The Laser Therapy

The Changes Of Corneal Endothelium After The Nd:YAG Laser TherapyObjectives: To explore the changes of corneal endothelium after the Nd:YAG 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.Results: Among the entire sufferer, 14 days later, in the center of the corneal endothelium, the decrease of the cell density revealed statistically significant difference (P<0.05). 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 (P<0.05). 7 days later, in the 5 o'clock periphery of the corneal endothelium, cell area; minimum cell area, cell density and percentage of hexagonal endothelium were analyzed statistically significant difference (P<0.05). 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 (p>0.05). Before and after the laser therapy, between the central and 6 o'clock periphery of corneal endothelium, there was all no statistically significant difference (p>0.05). Conclusion: The Nd:YAG laser peripheral iridectomy will damage to corneal endothelium. The treatment of posterior capsular opacification by using the Nd: YAG laser with the energy 2.6～3.2mj will not do the statistically significant damage to the corneal endothelium. The changes of corneal endothelium after the treatment of central serous choroidoretinopathy and diabetic retinopathy by using the 532nm laserObjectives: To explore the changes of corneal endothelium after the treatment of central serous choroidoretinopathy and diabetic retinopathy by using the 532nm laser.Methods: Use the corneal endothelium microscope to observe the corneal endothelium of the eyes which had been subjected to the treatment by using the 532nm laser.Results: There was no significant correlation between pre-and postoperative central and 6 o'clock periphery of corneal endothelium in 7,14 and 21 days after central serous choroidoretinopathy treatment(p>0.05); There was also no significant correlation between pre-and postoperative central and 6 o'clock periphery of corneal endothelium in 14 and 21 days after diabetic retinopathy treatment(p>0.05).Conclusion: 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.
