Abstract
Objective To observe the safety and efficacy of phacoemulsification combined with Ex-PRESS glaucoma drainage implantation for primary angle closure glaucoma with cataract. Methods A randomized prospective clinical case-control study, patients with primary angle closure glaucoma combined with cataract surgery from January 2013 to June 2015 in the department of ophthalmology of the third affiliated hospital of the third military medical university, random number table method was used to classify into two groups, 28 cases (30 eyes) were treated with phacoemulsification and intraocular lens implantation combined with Ex-PRESS glaucoma drainage implantation, 24 cases (28 eyes) were treated with phacoemulsification and intraocular lens implantation combined with trabeculectomy. The intraocular pressure, intraocular pressure, average operation time, open distance (AOD 500), trabecular iris angle (TIA), trabecular-ciliary process distance (TCPD) and complications were compared. Results Both the experiment group and the control group there was no significant difference on the intraocular pressure between the experimental group and control group, but there was no significant difference between the two groups. The average operation time and complication rate of the experimental group was significantly less than that of the control group (P 0.05). Conclusions After phacoemulsification, anterior chamber depth, opening of the anterior chamber angle, suitable for the Ex-PRESS drainage and implantation of the Ex-PRESS, the operation of the combined phacoemulsification and trabeculectomy combined with glaucoma drainage for the closure of glaucoma with cataract surgery is safe and effective. Key words: Cataract; Primary angle closure glaucoma; Phacoemulsification; Glaucoma drainage implant; Trabeculectomy
