AIM:To investigate the therapeutic effect and method of phacoemulsification and foldable intraocular lens (IOL) implantation associated with trabeculectomy in angle-closure glaucoma with cataract.METHODS:Phacoemulsification with implantation of foldable IOL associated with trabeculectomy was per-formed on 43 patients 43 eyes with cataract and angle-closure glaucoma through a 3.2mm hyaline corneal incision and another sclera incision.RESULTS:The post-operation vision >0.5 was in 26 cases (60%),between 0.1 to 0.5 in 17 cases(40%).The vision was improved in all cases.The average intraocular pressure 1 week after operation was 15.4±3.8mmHg,which was 10-30mmHg,lower than that before operation(P<0.01).42 eyes (98%) formed functional filtering bleb.CONCLUSION:Phacoemulsification and foldable IOL implantation associated with trabeculectomy in angle-closure glaucoma with cataract offers a safe and effective method to treat cataract with angle-closure glaucoma,and have a quicker visual recovery and good effect.
