AIM:To compare the control of intraocular pressure(IOP) and visual acuity postoperatively between combined surgery of cataract and glaucoma with small incision intraocular lens trabeculectomy and traditional trabeculetomy for primary angle-closure glaucoma.METHODS:The 118 cases 138 eyes with primary angle-closure glaucoma were divided two groups.Group A:47 cases 52 eyes underwent combined surgery of cataract and glaucoma with small incision introcular lens trabeculecto-my.Group B:71 cases 86 eyes underwent traditional trabeculetomy the postoperative control of IOP and visual acuity were compared and analyzed.RESULTS:One year after operation,IOP control rate in group A(89.6%) and group B(73.8%) had significant difference (χ2=4.36,P<0.05).One year after operation,the improvement of visual in acuity group A (0.33) and group B(0.09) had significant difference(t=3.584,P<0.05).CONCLUSION:The combined surgery of cataract and glaucoma with small incision introcular lens trabeculectomy has better effect in IOP’s control and visual acuity than traditional trabeculetomy.
