AIM:To investigate the effect of double incision trabeculectomy combined with phacoemulsification and intraocular lens implantation for the treatment of glaucoma complicated with cataract.

METHODS:Selected 36 patients(40 eyes)with acute or chronic angle-closure glaucoma and cataract in our hospital from June 2014 to January 2016 were treated with double incision trabeculectomy combined phacoemulsification and intraocular lens implantation. All patients were followed up for 1mo to observe preoperative and postoperative visual acuity, anterior chamber depth, scope of anterior chamber angle open and intraocular pressure. At the same time, we observed the patients' postoperative filtering bleb and intraoperative and postoperative complications.

RESULTS: Intraocular pressure before treatment were between 19-36mmHg, the average was 26.02±2.42 mmHg, and after the treatment intraocular pressure was patients between 11-22mmHg, the average was 13.62±4.38 mmHg, preoperative and postoperative intraocular pressure had the obvious difference(t=33.273, P<0.05). Preoperatively 85.0%(32 cases, 34 eyes)was with vision less than 0.3, and 53%(19 cases, 21 eyes)after surgery with eyesight over 0.3. All of the eyes formed good filtering bleb after surgery. Scope of anterior chamber angle open, anterior chamber angle open distance and central anterior chamber depth after operation increased in 36 cases compared with preoperative(t=5.832, 5.924, 33.293, P<0.05). There were 7 eyes with mild edema of the cornea, all disappear within 3d after surgery; one eye with bleeding when the iris was cut and absorbed after 2d; 4 eyes with fibrin effusion on lens surface and anterior chamber and absorbed with 6d. There were not any other severe complication in this study.

CONCLUSION: Double incision trabeculectomy combined with phacoemulsification and intraocular lens implantation for glaucoma with cataract can effectively improve the patient's vision, and can better control the intraocular pressure after surgery.
