Outcome and surgical techniques of phacoemulsification combined with goniosynechialysis in eyes with acute primary angle closure glaucoma and cataract

Abstract

AIM:To investigate the outcome and surgical techniques of phacoemulsification combined with goniosynechialysis in eyes with acute primary angle closure glaucoma(APACG)and cataract.METHODS: Sixty-seven patients(67 eyes)with APACG accompanied with cataract were treated with phacoemulsification from July 2012 to July 2014 in Zhongshan People's Hospital. Before operations, reducing intraocular press(IOP)sufficiently and relieving corneal edema were given to all patients. During the operations, goniosynechialysis were performed sufficiently. All patients were examined for visual acuity, IOP, number of anti-glaucoma drugs and range of opened anterior chamber preoperatively and at 3mo postoperatively. Data of anterior segment included central anterior chamber depth(CACD), anterior chamber volume(ACV), pupil diameter(PD)and others were detected by Pentacam and anterior segment ocular coherence tomography(AS-OCT). RESULTS: The visual acuity improved from 0.87±0.09 preoperatively to 0.23±0.08 postoperatively and the difference was statistically significant(t=4.086, Pt=20.266, Pt=24.266, P3 preoperatively to 148.65±17.85mm3 postoperatively(t=51.583, Pt=46.677,Pt=10.166, Pt=1.157, P=0.247). Posterior capsule rupture occurred in 1 eye. Anterior fibrinous membrane of intraocular lens occurred in 2 eyes. CONCLUSION: Phacoemulsification combined with goniosynechialysis can reduce IOP effectively and improve the stenosis of anterior segment, which is an useful treatment for patients with APACG and cataract.
