AIM: To evaluate the clinical effect of phacoemulsification with intraocular lens (IOL) implantation in the man-agement of angle-closure glaucoma combined with cataract and the value of ultrasound biomicroscope (UBM) in the surgeries. METHODS: Phacoemulsification with IOL implantation was performed on 56 cases (60 eyes). We grouped the eyes according to the preoperative UBM observation. (1) According to preoperative angle closure degrees and peripheral anterior synechiae, the patients were divided into three groups, group A1 was 6 eyes with less than 1/2 perimeter angle closure and peripheral anterior synechiae, group B1 was 24 eyes with more than 1/2 perimeter but less than 3/4 perimeter angle closure and peripheral anterior synechiae, group C1 was 30 eyes with more than 3/4 perimeter angle closure and peripheral anterior synechiae. (2) According to the lens thickness, the participants were assigned to two groups, group A2 was 36 eyes with the lens thickness (greater-than or equal to)4.80mm, group B2 was 24 eyes with the lens thickness < 4.80mm. The best corrected visual acuity (BCVA), intraocular pressure (IOP), anterior chamber angle and anterior chamber depth were measured and statistically analyzed with SSPS 13.0. RESULTS: The BCVA of the majority improved differently after the operation. The anterior chamber depth deepened and part of closure angle reopened again. There was no difference about IOP in group A1 but there was significant difference in group B1 and C1 between preoperation and postoperation. The IOP elevation recurred in 1 eye in group B1 and 8 eyes in group C1. There was significant difference in the success rate between group A2 and B2. CONCLUSION: Phacoemulsification with IOL implantation is promising for angle-closure glaucoma with less than 3/4 perimeter angle closure or synechiae, but the IOP elevation possibly recurred in that more than 3/4 perimeter angle closure or synechiae. UBM is very helpful for the selection of the operation. LA: Chinese
