Clinical study of phacoemulsification and intraocular lens implantation combined with goniosynechialysis in the treatment of primary chronic angle closure glaucoma

AIM:To evaluate the efficacy of phacoemulsification and intraocular lens(IOL)implantation combined with goniosynechialysis in the treatment of primary chronic angle closure glaucoma. METHODS: Eighty patients(96 eyes)with primary chronic angle closure glaucoma were divided into observation group(40 cases, 46 eyes)and control group(40 cases, 50 eyes). The treatment group was treated with phacoemulsification, intraocular lens implantation and goniosynechialysis, while the control group was treated with phacoemulsification and intraocular lens implantation. The best corrected visual acuity, intraocular pressure, visual field mean deviation(MD), mean sensitivity(MS)and the central anterior chamber depth of the two groups before and after the surgery were compared, and the occurrence of complications in patients with postoperative were record. RESULTS:The best corrected visual acuity, visual field, intraocular pressure and central anterior chamber depth of the two groups before operation showed no significant differences(P>0.05). The best corrected visual acuity, visual field, intraocular pressure and central anterior chamber depth between the groups at 6mo postoperatively showed statistically significant(Pχ2=0.351, P=2.095). CONCLUSION:The application of the phacoemulsification and intraocular lens implantation combined with goniosynechialysis in the treatment of primary chronic angle closure glaucoma is more effective than the simple use of phacoemulsification and intraocular lens implantation.
