Clinical observation of phacoemulsification treatment for primary angle-closure glaucoma complicated with cataract

Objective To explore the clinical curative effect of cataract phacoemulsification with artificial lens implantation for treatment of primary angle-closure glaucoma complicated with cataract.Methods Retrospective analyzed 26 patients of 30 eyes with primary angle-closure glaucoma complicated with cataract.The phacoemulsification with IOL implantation was performed.Visual acuity,anterior chamber depth,the change of the angle and intraocular pressure were observed before and after operation.Follow-up was for 12 to 24 months. Results Visual acuity of all patients had different improvement except 1 case had no improvement due to cystic macular degeneration.The best corrected visual acuity (BCVA) was 0.1-0.4 in 10 eyes (33.3％),0.5-0.8 in 18 eyes (60％),the greater than 1.0 in 2 eyes (6.7％).Temporary intraocular pressure (IOP) increased in 1 eye on the first day after surgery and backed to normal three days later after lower intraocular pressure eye drop treatment was given.One case had high intraocular pressure because the severe inflammatory response that caused iris adhesion and extensive adhesion to angle,that could not controlled by medication,and half years later received another trabeculectomy,then the IOP dropped to normal.Two eyes required eye drop to control the IOP,all other patients with IOP between 13 to 18 mmHg without any drugs. The central anterior chamber deepened from 1.65 +/-0.36mm preoperatively to2.57+/-0.46mm postoperatively,the angle opened at different degrees.The main complications were mild corneal edema and iris inflammation. Conclusions Cataract phacoemulsification with IOL implantation can deepen anterior chamber,open angle,reduce intraocular pressure effectively.It is effective treatment method for primary angle-closure glaucoma complicated with cataract and to provide better vision for patients.
