AIM:To evaluate the therapeutic effects of one incision phacoemulsification and intraocular lens(IOL) implantation combined with trabeculectomy (triple surgery) in the treatment of glaucoma combined with cataract. METHODS:A total of 30 cases (34 eyes ) with coexisting glaucoma and cataract, who were performed triple surgery from January 2008 to February 2009 in our hospital, were retrospectively analyzed. Preoperative and postoperative visual acuity intraocular pressure (IOP) and complications were observed, and all cases were followed up for 24 to 36 months. RESULTS:Preoperative mean visual acuity was 4.21±0.42. Postoperative mean visual acuity was 4.67±0.22. There was significant difference between before and after operation (t=-5.794,P<0.01).The postoperative IOP of 34 eyes were normal without any other treatments, the mean IOP decreased from preoperative 23.67±9.12mmHg to postoperative 15.90±2.74mmHg .There was significant difference between before and after operation (t=5.162, P<0.01). 34 eyes didn’t occur serious complications. CONCLUSION:One incision triple surgery could control IOP effectively and improve visual acuity quickly and remarkably.
