AIM: To observe the clinical effect of small - incision extracapsular cataract extraction ( ECCE ) with posterior chamber intraocular lens implantation combined with goniosynechialysis and trabeculectomy for the treatment of chronic angle-closure glaucoma with cataract. METHODS:Twenty cases (26 eyes) with chronic angleclosure glaucoma and cataract were performed combined surgery. The postoperative visual acuity, intraocular pressure ( IOP ), anterior chamber angle, filtering bleb morphology and complications were all observed and reported. The follow-up was 4-10 months. RESULTS:All the patients' visual acuity were improved in different degrees, All eyes had normal IOP. The angleclosure can be partly opened and the range of goniosynechia can be decreased after surgery. Twenty - two eyes had functional filtering bleb. The major complications were anterior chamber hemorrhage and transient corneal edema. CONCLUSION:Combined surgery for the treatment of chronic angle - closure glaucoma with cataract can effectively control IOP and improve visual acuity. It is safe and effective.
