Clinical study of ultrasonic emulsification operation in the treatment of glaucoma with cataract

Objective To investigate the clinical effects of phacoemulsification with foldable posterior cham-ber intraocular lens implantation in the treatment of primary angle closure glaucoma with cataract .Methods 82 patients（82 eyes） with primary angle closure glaucoma with cataract were selected as the research objects ,and taken the treatment of combination of phacoemulsification and posterior chamber foldable intraocular lens implanta -tion.c The vision,intraocular pressure ,anterior chamber depth and angle opening changes before and after 6 months of operation were ompared ,and the postoperative complications were observed .Results 54 eyes achieved best corrected visual acuity of more than 0.5,12 eyes achieved best corrected visual acuity of 0.4,6 eyes achieved best corrected visual acuity among 0.1 to 0.3 and 6 eyes achieved best corrected visual acuity of less than 0.1.The difference between postoperative best corrected visual acuity and that before operation had significant statistical differences （χ2 =43.244,P〈0.01）.After having the operation ,the intraocular pressure of acute closed angle glaucoma pre clinic , onset period and chronic angle closure glaucoma had significantly improved compared to pre -operation （ t=7.955, 4.741,5.638,all P〈0.01）.The chamber depth of the three groups had also improved substantially compared to that of pre-operation（t=13.080,11.890,16.124,all P〈0.01）.The degree of angle opening of acute closed angle glau-coma and chronic angle closure glaucoma were better than that of pre-operation,and postoperatively ,the degree of an-gle opening of the former turned out to be wider than that of the latter （χ2 =9.246,P〈0.05）.There were no postop-erative intraocular lens clamping,corneal decomposition,severe complication of retinal detachment and macular cys-toids edema .Conclusion The phacoemulsification combined with intraocular lens implantation for the treatment of primary angle closure glaucoma with cataract can effectively improve visual acuity ,control intraocular pressure ,deepen the anterior chamber ,open angle ,and the adverse reactions occurred less ,which is worthy of clinical application .
