AIM:To investigate the small incision extracapsular cataract extraction and posterior chamber intraocular lens capsular bag implantation combined with presetting trabecular incision trabeculectomy for treatment of glaucoma complicated with cataract clinical curative effect. METHODS:Twenty-one cases with coexisting cataract and glaucoma were performed cataract extracapsular extraction and posterior chamber intraocular lens capsular bag implantation combined with presetting trabecular incision trabeculectomy. Postoperative visual acuity, intraocular pressure and complications were observed. RESULTS:All patients postoperative intraocular pressure decreased to normal range. Postoperative visual acuity improved to different degrees. After surgery in 1 eye occurred early anterior membrane of intraocular lens, 2 eyes appeared transient corneal edema. CONCLUSION: Presetting trabecular incision in small incision extracapsular cataract extraction and posterior chamber intraocular lens implantation combined with trabeculectomy is safe, effective and economical, which is worthy of promoting.
