Effect of 532nm Laser Combined with Nd:YAG Laser in Periiridectomy
Objective To investigate the effect of 532 nm laser combined with Nd∶YAG laser for periiridectomy in pa-tients with angle closure glaucoma.Methods A total of 82 patients with angle closure glaucoma from Yixing Hospital of Traditional Chinese Medicine from January 2020 to December 2023 were conveniently selected as the study objects and divided into observation group and reference group by blind touch dichroic ball method,with 41 cases in each group.The reference group was treated with Nd∶YAG laser for periiridectomy.The observation group was treated with Nd∶YAG laser for periiridectomy after 532 nm laser for cautery of periiridectomy.The surgical indexes,treatment out-comes,and intraocular pressure levels between two groups were compared.Results The total number of laser points,laser energy and primary iris penetration in observation group were significantly better than those in reference group,and the differences were statistically significant(all P<0.05).The total effective rate of treatment of observation group(97.56%)was higher than that of reference group(82.93%),and the difference was statistically significant(χ2=4.987,P<0.05).The intraocular pressure level of the observation group at 1 h and 7 d after operation was significantly better than that of the reference group,and the differences were statistically significant(both P<0.05).Conclusion Periiridec-tomy with 532 nm laser combined with Nd∶YAG laser can significantly improve the surgical situation and treatment effect of glaucoma patients,and the intraocular pressure can be significantly reduced.
